A client with asthma is prescribed an albuterol inhaler. Which instruction should the nurse provide?
Select the best answer.
Explanation:
The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.
An elderly client is concerned about constipation during a flight. What should the nurse recommend?
Select the best answer.
Explanation:
The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.
The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?
Select the best answer.
Explanation:
The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.
What is the primary purpose of a chest tube in a client's care?
Select the best answer.
Explanation:
The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.
Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)
Select the best answer.
Explanation:
Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.
A terminally ill male client and his family request hospice care after discharge. What aspect of care should the nurse indicate is the focus of hospice?
Select the best answer.
Explanation:
The correct answer is A. Hospice care focuses on enhancing symptom management to improve the end-of-life quality for terminally ill patients and their families. Hospice aims to provide comfort, dignity, and support during the end-of-life journey. Choice B is incorrect as hospice care does not involve assisted suicide but focuses on providing palliative care. Choice C is incorrect as hospice care does not aim to postpone the death experience but rather to provide support and comfort during this time. Choice D is incorrect as while hospice care may involve educating family members on caring for the client, the primary focus is on symptom management and quality of life.
The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?
Select the best answer.
Explanation:
After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
During a tonic-clonic seizure, what is the nurse's priority intervention?
Select the best answer.
Explanation:
During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.
A client with chronic kidney disease is receiving hemodialysis. Which assessment finding should the nurse report to the healthcare provider immediately?
Select the best answer.
Explanation:
The correct answer is C. An elevated blood pressure in clients with chronic kidney disease undergoing hemodialysis can indicate fluid overload or poor dialysis efficacy and should be reported immediately. This finding could lead to complications such as heart failure or pulmonary edema. Choices A, B, and D are not as critical in this situation. Decreased urine output may be expected due to the kidney disease, a weight loss of 1 kg is within an acceptable range, and the presence of a bruit over the fistula is a common finding in clients undergoing hemodialysis and does not require immediate reporting.
The nurse is caring for a client who is 4 hours post-operative from abdominal surgery. The client is complaining of severe pain. What is the nurse's first action?
Select the best answer.
Explanation:
The correct first action for the nurse to take when a post-operative client complains of severe pain is to reassess the pain and its characteristics. Reassessment is crucial to understand the nature and intensity of the pain, which will guide the nurse in providing appropriate interventions. Administering pain medication may be necessary but should only be done after reassessment to ensure the right medication and dose are given. Notifying the surgeon may be required in certain situations, but reassessment of pain should precede this action. Encouraging relaxation techniques is not the priority when a client is experiencing severe pain post-operatively.
A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?
Select the best answer.
Explanation:
The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.
During the shift change report at an acute care hospital, the charge nurse assigns the Licensed Practical Nurse (LPN) to care for a client. Which task is within the LPN's scope?
Select the best answer.
Explanation:
The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.
The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?
Select the best answer.
Explanation:
The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.
The nurse observes a client with new-onset tachycardia. What should the nurse do first?
Select the best answer.
Explanation:
When a client presents with new-onset tachycardia, the first action the nurse should take is to assess for any associated symptoms like chest pain or discomfort. This is important to differentiate the potential causes of tachycardia and guide appropriate interventions. Checking the client's temperature (Choice A) may be relevant in certain situations but is not the priority when tachycardia is observed. Administering prescribed beta-blockers (Choice B) should only be done after a comprehensive assessment and healthcare provider's orders. Monitoring the client's blood pressure (Choice D) is important, but assessing for chest pain or discomfort takes precedence in this scenario to rule out cardiac causes of tachycardia.
The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?
Select the best answer.
Explanation:
The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.
A client is receiving dexamethasone (Decadron). What symptoms should the nurse recognize as Cushingoid side effects?
Select the best answer.
Explanation:
Cushingoid side effects are characteristic of excess corticosteroid use, such as dexamethasone. These include moon face (rounding of the face), slow wound healing, muscle wasting, and sodium and water retention. Options B, C, and D describe symptoms that are not typically associated with Cushingoid side effects. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor (Option B) are not typical of Cushingoid effects, while bradycardia, weight gain, cold intolerance, myxedema facies, and periorbital edema (Option C) are more indicative of hypothyroidism. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, and hypotension (Option D) are not classical features of Cushingoid side effects.
The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
Select the best answer.
Explanation:
After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
After placing a client at 26-weeks gestation in the lithotomy position, the client complains of dizziness and becomes pale and diaphoretic. What action should the nurse implement?
Select the best answer.
Explanation:
Placing a wedge under the client's hip is the correct action in this scenario. This helps relieve the pressure on the vena cava, which can become compressed in the lithotomy position during pregnancy, improving circulation and reducing symptoms like dizziness and pallor. Instructing the client to take deep breaths (Choice A) may not address the underlying cause of the symptoms. Placing the client in the Trendelenburg position (Choice C) would worsen the situation by further compressing the vena cava. Removing the client's legs from the stirrups (Choice D) may provide temporary relief but does not address the root cause of the issue.
A client with a cast complains of numbness and tingling in the affected limb. What should the nurse do first?
Select the best answer.
Explanation:
The correct first action for a client with a cast experiencing numbness and tingling in the affected limb is to check for tightness of the cast. Numbness and tingling can indicate compromised circulation, and a tight cast may be causing this. Checking the cast for tightness is essential to ensure it is not impeding circulation. Elevating the limb, applying ice, or notifying the physician can be subsequent actions depending on the assessment findings after checking the cast. Elevating the limb might help improve circulation, applying ice is not indicated for numbness and tingling, and notifying the physician can be done if the issue persists after addressing the immediate concern of cast tightness.
A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
Select the best answer.
Explanation:
The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
What is the most important aspect of colostomy care to teach the client?
Select the best answer.
Explanation:
The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.
A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?
Select the best answer.
Explanation:
After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.
The nurse assigns an unlicensed assistive personnel (UAP) to feed a client who is at risk for aspiration. What action should the nurse take to ensure safety?
Select the best answer.
Explanation:
Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.
A 4-year-old with acute lymphocytic leukemia (ALL) is receiving a chemotherapy protocol that includes methotrexate, an antimetabolite. Which information should the nurse provide the parents about caring for their child?
Select the best answer.
Explanation:
The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.
A healthcare provider is conducting a health education session about the prevention of type 2 diabetes. What lifestyle modification should be emphasized?
Select the best answer.
Explanation:
To effectively prevent type 2 diabetes, individuals should focus on a combination of lifestyle modifications. Increasing physical activity helps maintain a healthy weight and improves insulin sensitivity. Reducing dietary sugar intake can lower the risk of developing diabetes by managing blood sugar levels. Regular health screenings are crucial for early detection and timely intervention. Emphasizing all these modifications together provides a comprehensive approach to diabetes prevention. Choices A, B, and C are all important components of a healthy lifestyle that can contribute to reducing the risk of type 2 diabetes.
The nurse is palpating the right upper hypochondriac region of the abdomen of a client. What organ lies underneath this area?
Select the best answer.
Explanation:
The correct answer is C: Liver. The liver is located in the right upper hypochondriac region of the abdomen. The duodenum (Choice A) is located in the right upper quadrant but not directly underneath the right upper hypochondriac region. The gastric pylorus (Choice B) is part of the stomach and is located more centrally in the abdomen. The spleen (Choice D) is located in the left upper quadrant of the abdomen, not underneath the right upper hypochondriac region.
The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?
Select the best answer.
Explanation:
The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which instruction should the nurse provide to the client?
Select the best answer.
Explanation:
Reporting signs of bleeding is essential while on anticoagulant therapy to prevent complications.
The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?
Select the best answer.
Explanation:
The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
The nurse is caring for a client who has just undergone a total hip replacement. Which intervention is most important to prevent postoperative complications?
Select the best answer.
Explanation:
Encouraging early ambulation is crucial following a total hip replacement surgery as it helps prevent complications such as deep vein thrombosis (DVT) by promoting circulation. Early ambulation also aids in preventing pneumonia, muscle atrophy, and pressure ulcers. Applying ice to the surgical site may help with pain and swelling, but it is not as critical in preventing complications as early ambulation. While monitoring the surgical site for signs of infection is important, it is not as crucial in preventing postoperative complications compared to early ambulation. Administering pain medication as prescribed is essential for comfort and pain management but does not directly prevent postoperative complications like early ambulation does.
An adult female client is admitted to the psychiatric unit with a diagnosis of major depression. After 2 weeks of antidepressant medication therapy, the nurse notices the client has more energy, is giving her belongings away to her visitors, and is in an overall better mood. Which intervention is best for the nurse to implement?
Select the best answer.
Explanation:
In this scenario, the nurse should ask the client if she has had any recent thoughts of harming herself. Sudden mood improvements and behavioral changes, like giving away belongings, can be concerning signs of possible suicidal ideation. Assessing for suicidal thoughts is crucial to ensure the client's safety. Choice A is incorrect as it does not address the potential risk of harm or assess for suicidal ideation. Choice C is incorrect because simply reassuring the client about the effectiveness of antidepressants does not address the immediate concern of suicidal ideation. Choice D is incorrect as it focuses on praising progress without addressing the potential risk of harm the client may pose to herself.
How should the nurse assess for cyanosis in a client with dark skin who is in respiratory distress?
Select the best answer.
Explanation:
Observing the lips and mucous membranes provides a reliable indicator of cyanosis in clients with dark skin tones. Choice A is incorrect because cyanosis can be assessed in clients with dark skin by observing other body areas. Choice B is incorrect as blanching the soles of the feet is not a relevant method for assessing cyanosis. Choice D is incorrect as cyanosis is not typically seen in the sclera in clients with dark skin.
A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?
Select the best answer.
Explanation:
The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?
Select the best answer.
Explanation:
When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
How should the nurse respond to an older male client who states that his religion does not permit him to bathe daily?
Select the best answer.
Explanation:
The correct response is to offer the client several choices of times to bathe during the day. This approach respects the client's religious beliefs while ensuring that hygienic practices are still maintained. By providing options, the nurse can work together with the client to find a solution that aligns with both his beliefs and his health needs. Choice A is incorrect because solely reviewing the importance of hygiene may not address the client's specific religious concerns. Choice B is inappropriate as it disregards the client's beliefs and autonomy. Choice D is not the best approach as it may come off as confrontational or dismissive of the client's beliefs, rather than working collaboratively to find a suitable solution.
A client with asthma is prescribed a corticosteroid inhaler. What instruction should the nurse give about the inhaler?
Select the best answer.
Explanation:
The correct instruction for a client using a corticosteroid inhaler is to rinse the mouth after each use to prevent the development of oral thrush, a common side effect of these inhalers. Choice A is incorrect as corticosteroid inhalers are often used regularly as a maintenance treatment, not just during asthma attacks. Choice C is incorrect because corticosteroid inhalers provide long-term control of asthma symptoms, not immediate relief during an attack. Choice D is incorrect and potentially dangerous advice as increasing the dose without medical guidance can lead to adverse effects.
A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?
Select the best answer.
Explanation:
In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.
The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?
Select the best answer.
Explanation:
The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.
The nurse is caring for a client postoperatively following a hip replacement. Which intervention is most important to prevent dislocation of the prosthesis?
Select the best answer.
Explanation:
Maintaining hip abduction with pillows is crucial in preventing dislocation of the hip prosthesis postoperatively. This position helps keep the hip joint stable and reduces the risk of the prosthesis becoming displaced. Choices A, C, and D are not as effective in preventing dislocation. Keeping the client in a low Fowler's position does not provide the necessary hip support. While early ambulation is important for circulation and preventing complications, maintaining hip abduction is more specific to preventing prosthesis dislocation. Placing the client in a prone position can increase the risk of hip prosthesis dislocation due to the extreme positioning.
What is the primary function of neutrophils?
Select the best answer.
Explanation:
The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?
Select the best answer.
Explanation:
The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.
The healthcare provider is assessing a client who has just undergone a thoracentesis. Which finding should be reported immediately?
Select the best answer.
Explanation:
Shortness of breath should be reported immediately as it may indicate a pneumothorax, a potential complication of thoracentesis. Diminished breath sounds on the affected side, pain at the procedure site, and blood-tinged sputum are common findings post-thoracentesis and do not necessarily indicate immediate complications like a pneumothorax.
The nurse is caring for a client who has just received a blood transfusion. The client reports chills and back pain. What is the nurse's priority action?
Select the best answer.
Explanation:
Chills and back pain are signs of a possible transfusion reaction, which can indicate severe complications like a hemolytic reaction or sepsis. The priority action for the nurse is to stop the transfusion immediately to prevent further harm to the client. Slowing the rate of the transfusion or administering an antipyretic will not address the underlying cause of the reaction and could potentially worsen the client's condition. Notifying the healthcare provider should be done after ensuring the client's immediate safety by stopping the transfusion.
When reconstituted, how many milligrams are in each milliliter of solution?
Select the best answer.
Explanation:
After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.
A client with a history of pulmonary embolism is on anticoagulant therapy. What should the nurse monitor regularly?
Select the best answer.
Explanation:
Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.
A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?
Select the best answer.
Explanation:
The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
Which client will benefit most from the application of pneumatic compression devices to the lower extremities? The client who
Select the best answer.
Explanation:
The correct answer is A. Pneumatic compression devices are most beneficial for immobile clients on prescribed bedrest to prevent deep vein thrombosis. Applying these devices helps in promoting circulation and preventing blood clots. Choices B, C, and D do not specifically relate to the primary indication for pneumatic compression devices, making them incorrect. Pressure ulcers, diminished pedal pulse volume, and confusion with climbing out of bed may require different interventions or treatments.
When teaching a group of school-aged children how to reduce the risk for Lyme disease, which instruction should the camp nurse include?
Select the best answer.
Explanation:
The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.
A client with asthma is prescribed an albuterol inhaler. Which instruction should the nurse provide?
Select the best answer.
Explanation:
The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.
An elderly client is concerned about constipation during a flight. What should the nurse recommend?
Select the best answer.
Explanation:
The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.
The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?
Select the best answer.
Explanation:
The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.
What is the primary purpose of a chest tube in a client's care?
Select the best answer.
Explanation:
The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.
Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)
Select the best answer.
Explanation:
Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.
A terminally ill male client and his family request hospice care after discharge. What aspect of care should the nurse indicate is the focus of hospice?
Select the best answer.
Explanation:
The correct answer is A. Hospice care focuses on enhancing symptom management to improve the end-of-life quality for terminally ill patients and their families. Hospice aims to provide comfort, dignity, and support during the end-of-life journey. Choice B is incorrect as hospice care does not involve assisted suicide but focuses on providing palliative care. Choice C is incorrect as hospice care does not aim to postpone the death experience but rather to provide support and comfort during this time. Choice D is incorrect as while hospice care may involve educating family members on caring for the client, the primary focus is on symptom management and quality of life.
The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?
Select the best answer.
Explanation:
After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
During a tonic-clonic seizure, what is the nurse's priority intervention?
Select the best answer.
Explanation:
During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.
A client with chronic kidney disease is receiving hemodialysis. Which assessment finding should the nurse report to the healthcare provider immediately?
Select the best answer.
Explanation:
The correct answer is C. An elevated blood pressure in clients with chronic kidney disease undergoing hemodialysis can indicate fluid overload or poor dialysis efficacy and should be reported immediately. This finding could lead to complications such as heart failure or pulmonary edema. Choices A, B, and D are not as critical in this situation. Decreased urine output may be expected due to the kidney disease, a weight loss of 1 kg is within an acceptable range, and the presence of a bruit over the fistula is a common finding in clients undergoing hemodialysis and does not require immediate reporting.
The nurse is caring for a client who is 4 hours post-operative from abdominal surgery. The client is complaining of severe pain. What is the nurse's first action?
Select the best answer.
Explanation:
The correct first action for the nurse to take when a post-operative client complains of severe pain is to reassess the pain and its characteristics. Reassessment is crucial to understand the nature and intensity of the pain, which will guide the nurse in providing appropriate interventions. Administering pain medication may be necessary but should only be done after reassessment to ensure the right medication and dose are given. Notifying the surgeon may be required in certain situations, but reassessment of pain should precede this action. Encouraging relaxation techniques is not the priority when a client is experiencing severe pain post-operatively.
A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?
Select the best answer.
Explanation:
The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.
During the shift change report at an acute care hospital, the charge nurse assigns the Licensed Practical Nurse (LPN) to care for a client. Which task is within the LPN's scope?
Select the best answer.
Explanation:
The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.
The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?
Select the best answer.
Explanation:
The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.
The nurse observes a client with new-onset tachycardia. What should the nurse do first?
Select the best answer.
Explanation:
When a client presents with new-onset tachycardia, the first action the nurse should take is to assess for any associated symptoms like chest pain or discomfort. This is important to differentiate the potential causes of tachycardia and guide appropriate interventions. Checking the client's temperature (Choice A) may be relevant in certain situations but is not the priority when tachycardia is observed. Administering prescribed beta-blockers (Choice B) should only be done after a comprehensive assessment and healthcare provider's orders. Monitoring the client's blood pressure (Choice D) is important, but assessing for chest pain or discomfort takes precedence in this scenario to rule out cardiac causes of tachycardia.
The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?
Select the best answer.
Explanation:
The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.
A client is receiving dexamethasone (Decadron). What symptoms should the nurse recognize as Cushingoid side effects?
Select the best answer.
Explanation:
Cushingoid side effects are characteristic of excess corticosteroid use, such as dexamethasone. These include moon face (rounding of the face), slow wound healing, muscle wasting, and sodium and water retention. Options B, C, and D describe symptoms that are not typically associated with Cushingoid side effects. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor (Option B) are not typical of Cushingoid effects, while bradycardia, weight gain, cold intolerance, myxedema facies, and periorbital edema (Option C) are more indicative of hypothyroidism. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, and hypotension (Option D) are not classical features of Cushingoid side effects.
The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
Select the best answer.
Explanation:
After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
After placing a client at 26-weeks gestation in the lithotomy position, the client complains of dizziness and becomes pale and diaphoretic. What action should the nurse implement?
Select the best answer.
Explanation:
Placing a wedge under the client's hip is the correct action in this scenario. This helps relieve the pressure on the vena cava, which can become compressed in the lithotomy position during pregnancy, improving circulation and reducing symptoms like dizziness and pallor. Instructing the client to take deep breaths (Choice A) may not address the underlying cause of the symptoms. Placing the client in the Trendelenburg position (Choice C) would worsen the situation by further compressing the vena cava. Removing the client's legs from the stirrups (Choice D) may provide temporary relief but does not address the root cause of the issue.
A client with a cast complains of numbness and tingling in the affected limb. What should the nurse do first?
Select the best answer.
Explanation:
The correct first action for a client with a cast experiencing numbness and tingling in the affected limb is to check for tightness of the cast. Numbness and tingling can indicate compromised circulation, and a tight cast may be causing this. Checking the cast for tightness is essential to ensure it is not impeding circulation. Elevating the limb, applying ice, or notifying the physician can be subsequent actions depending on the assessment findings after checking the cast. Elevating the limb might help improve circulation, applying ice is not indicated for numbness and tingling, and notifying the physician can be done if the issue persists after addressing the immediate concern of cast tightness.
A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
Select the best answer.
Explanation:
The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
What is the most important aspect of colostomy care to teach the client?
Select the best answer.
Explanation:
The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.
A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?
Select the best answer.
Explanation:
After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.
The nurse assigns an unlicensed assistive personnel (UAP) to feed a client who is at risk for aspiration. What action should the nurse take to ensure safety?
Select the best answer.
Explanation:
Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.
A 4-year-old with acute lymphocytic leukemia (ALL) is receiving a chemotherapy protocol that includes methotrexate, an antimetabolite. Which information should the nurse provide the parents about caring for their child?
Select the best answer.
Explanation:
The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.
A healthcare provider is conducting a health education session about the prevention of type 2 diabetes. What lifestyle modification should be emphasized?
Select the best answer.
Explanation:
To effectively prevent type 2 diabetes, individuals should focus on a combination of lifestyle modifications. Increasing physical activity helps maintain a healthy weight and improves insulin sensitivity. Reducing dietary sugar intake can lower the risk of developing diabetes by managing blood sugar levels. Regular health screenings are crucial for early detection and timely intervention. Emphasizing all these modifications together provides a comprehensive approach to diabetes prevention. Choices A, B, and C are all important components of a healthy lifestyle that can contribute to reducing the risk of type 2 diabetes.
The nurse is palpating the right upper hypochondriac region of the abdomen of a client. What organ lies underneath this area?
Select the best answer.
Explanation:
The correct answer is C: Liver. The liver is located in the right upper hypochondriac region of the abdomen. The duodenum (Choice A) is located in the right upper quadrant but not directly underneath the right upper hypochondriac region. The gastric pylorus (Choice B) is part of the stomach and is located more centrally in the abdomen. The spleen (Choice D) is located in the left upper quadrant of the abdomen, not underneath the right upper hypochondriac region.
The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?
Select the best answer.
Explanation:
The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which instruction should the nurse provide to the client?
Select the best answer.
Explanation:
Reporting signs of bleeding is essential while on anticoagulant therapy to prevent complications.
The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?
Select the best answer.
Explanation:
The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
The nurse is caring for a client who has just undergone a total hip replacement. Which intervention is most important to prevent postoperative complications?
Select the best answer.
Explanation:
Encouraging early ambulation is crucial following a total hip replacement surgery as it helps prevent complications such as deep vein thrombosis (DVT) by promoting circulation. Early ambulation also aids in preventing pneumonia, muscle atrophy, and pressure ulcers. Applying ice to the surgical site may help with pain and swelling, but it is not as critical in preventing complications as early ambulation. While monitoring the surgical site for signs of infection is important, it is not as crucial in preventing postoperative complications compared to early ambulation. Administering pain medication as prescribed is essential for comfort and pain management but does not directly prevent postoperative complications like early ambulation does.
An adult female client is admitted to the psychiatric unit with a diagnosis of major depression. After 2 weeks of antidepressant medication therapy, the nurse notices the client has more energy, is giving her belongings away to her visitors, and is in an overall better mood. Which intervention is best for the nurse to implement?
Select the best answer.
Explanation:
In this scenario, the nurse should ask the client if she has had any recent thoughts of harming herself. Sudden mood improvements and behavioral changes, like giving away belongings, can be concerning signs of possible suicidal ideation. Assessing for suicidal thoughts is crucial to ensure the client's safety. Choice A is incorrect as it does not address the potential risk of harm or assess for suicidal ideation. Choice C is incorrect because simply reassuring the client about the effectiveness of antidepressants does not address the immediate concern of suicidal ideation. Choice D is incorrect as it focuses on praising progress without addressing the potential risk of harm the client may pose to herself.
How should the nurse assess for cyanosis in a client with dark skin who is in respiratory distress?
Select the best answer.
Explanation:
Observing the lips and mucous membranes provides a reliable indicator of cyanosis in clients with dark skin tones. Choice A is incorrect because cyanosis can be assessed in clients with dark skin by observing other body areas. Choice B is incorrect as blanching the soles of the feet is not a relevant method for assessing cyanosis. Choice D is incorrect as cyanosis is not typically seen in the sclera in clients with dark skin.
A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?
Select the best answer.
Explanation:
The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?
Select the best answer.
Explanation:
When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
How should the nurse respond to an older male client who states that his religion does not permit him to bathe daily?
Select the best answer.
Explanation:
The correct response is to offer the client several choices of times to bathe during the day. This approach respects the client's religious beliefs while ensuring that hygienic practices are still maintained. By providing options, the nurse can work together with the client to find a solution that aligns with both his beliefs and his health needs. Choice A is incorrect because solely reviewing the importance of hygiene may not address the client's specific religious concerns. Choice B is inappropriate as it disregards the client's beliefs and autonomy. Choice D is not the best approach as it may come off as confrontational or dismissive of the client's beliefs, rather than working collaboratively to find a suitable solution.
A client with asthma is prescribed a corticosteroid inhaler. What instruction should the nurse give about the inhaler?
Select the best answer.
Explanation:
The correct instruction for a client using a corticosteroid inhaler is to rinse the mouth after each use to prevent the development of oral thrush, a common side effect of these inhalers. Choice A is incorrect as corticosteroid inhalers are often used regularly as a maintenance treatment, not just during asthma attacks. Choice C is incorrect because corticosteroid inhalers provide long-term control of asthma symptoms, not immediate relief during an attack. Choice D is incorrect and potentially dangerous advice as increasing the dose without medical guidance can lead to adverse effects.
A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?
Select the best answer.
Explanation:
In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.
The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?
Select the best answer.
Explanation:
The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.
The nurse is caring for a client postoperatively following a hip replacement. Which intervention is most important to prevent dislocation of the prosthesis?
Select the best answer.
Explanation:
Maintaining hip abduction with pillows is crucial in preventing dislocation of the hip prosthesis postoperatively. This position helps keep the hip joint stable and reduces the risk of the prosthesis becoming displaced. Choices A, C, and D are not as effective in preventing dislocation. Keeping the client in a low Fowler's position does not provide the necessary hip support. While early ambulation is important for circulation and preventing complications, maintaining hip abduction is more specific to preventing prosthesis dislocation. Placing the client in a prone position can increase the risk of hip prosthesis dislocation due to the extreme positioning.
What is the primary function of neutrophils?
Select the best answer.
Explanation:
The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?
Select the best answer.
Explanation:
The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.
The healthcare provider is assessing a client who has just undergone a thoracentesis. Which finding should be reported immediately?
Select the best answer.
Explanation:
Shortness of breath should be reported immediately as it may indicate a pneumothorax, a potential complication of thoracentesis. Diminished breath sounds on the affected side, pain at the procedure site, and blood-tinged sputum are common findings post-thoracentesis and do not necessarily indicate immediate complications like a pneumothorax.
The nurse is caring for a client who has just received a blood transfusion. The client reports chills and back pain. What is the nurse's priority action?
Select the best answer.
Explanation:
Chills and back pain are signs of a possible transfusion reaction, which can indicate severe complications like a hemolytic reaction or sepsis. The priority action for the nurse is to stop the transfusion immediately to prevent further harm to the client. Slowing the rate of the transfusion or administering an antipyretic will not address the underlying cause of the reaction and could potentially worsen the client's condition. Notifying the healthcare provider should be done after ensuring the client's immediate safety by stopping the transfusion.
When reconstituted, how many milligrams are in each milliliter of solution?
Select the best answer.
Explanation:
After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.
A client with a history of pulmonary embolism is on anticoagulant therapy. What should the nurse monitor regularly?
Select the best answer.
Explanation:
Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.
A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?
Select the best answer.
Explanation:
The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
Which client will benefit most from the application of pneumatic compression devices to the lower extremities? The client who
Select the best answer.
Explanation:
The correct answer is A. Pneumatic compression devices are most beneficial for immobile clients on prescribed bedrest to prevent deep vein thrombosis. Applying these devices helps in promoting circulation and preventing blood clots. Choices B, C, and D do not specifically relate to the primary indication for pneumatic compression devices, making them incorrect. Pressure ulcers, diminished pedal pulse volume, and confusion with climbing out of bed may require different interventions or treatments.
When teaching a group of school-aged children how to reduce the risk for Lyme disease, which instruction should the camp nurse include?
Select the best answer.
Explanation:
The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.
During a routine prenatal visit, a nurse measures a client's fundal height at 26 weeks gestation. What should the fundal height be?
Select the best answer.
Explanation:
The correct answer is B: 'Between 24 to 28 cm.' Fundal height is expected to be approximately equal to the weeks of gestation, so at 26 weeks, the fundal height should typically range between 24 to 28 cm. Choice A is incorrect because fundal height is not an exact measurement of gestational age in centimeters. Choice C is incorrect as it provides a general description above the umbilicus, which is not specific to 26 weeks gestation. Choice D is incorrect as the fundal height would not reach below the xiphoid process at 26 weeks gestation.
