1. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
2. A nurse is caring for a client who is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump. Which action is most important for the nurse to implement?
- A. Monitor the client's respiratory status
- B. Teach the client how to use the PCA pump
- C. Evaluate the client's pain level
- D. Assess the client's pain level
Correct answer: A
Rationale: When a client is receiving opioids like morphine sulfate via a PCA pump, the most critical action for the nurse to implement is to monitor the client's respiratory status. Opioids can cause respiratory depression, which can be life-threatening. Monitoring respiratory status allows for early detection of any signs of respiratory compromise. Teaching the client how to use the PCA pump, evaluating pain level, and assessing pain level are important aspects of care but ensuring the client's safety by monitoring respiratory status takes precedence due to the potential risks associated with opioid administration.
3. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, 'I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home'. What response is best for the nurse to provide?
- A. Heparin prevents future clot formation, but your risk of bleeding needs to be monitored closely
- B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
- C. Let me contact your surgeon and find out if Heparin IV therapy can be administered to you at home
- D. Why are you so anxious to leave the hospital when you know you are not well enough yet?
Correct answer: A
Rationale: Choice A is the best response because it educates the client about the role of heparin in preventing future clot formation rather than dissolving the existing clot. This helps the client understand the medication's function and the importance of closely monitoring for signs of bleeding, a common side effect of heparin therapy. Choice B acknowledges the client's concern but does not provide accurate information about heparin's mechanism of action. Choice C is premature as it suggests transitioning to home therapy without addressing the client's concerns or explaining heparin's purpose. Choice D does not address the client's statement and instead questions their desire to leave the hospital.
4. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?
- A. Exhibits adequate tissue perfusion
- B. Remains free of injury
- C. Remains free of infection
- D. Maintains effective breathing pattern
Correct answer: D
Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.
5. A client who has had three spontaneous abortions is requesting information about possible causes. The nurse's response should be based on which information?
- A. Chromosomal abnormalities are the most common cause of early spontaneous abortions
- B. Incompetent cervix can cause spontaneous abortions
- C. An infection can cause spontaneous abortions
- D. Nutritional deficiencies are the most common cause of early spontaneous abortions
Correct answer: A
Rationale: The correct answer is A: Chromosomal abnormalities are the most common cause of early spontaneous abortions. Spontaneous abortions, also known as miscarriages, often occur due to chromosomal abnormalities in the fetus. These abnormalities are a common cause of early pregnancy loss. Choice B is incorrect because an incompetent cervix typically leads to late miscarriages, not early spontaneous abortions. Choice C is incorrect as while infections can be a cause of spontaneous abortions, they are not the most common cause. Choice D is incorrect as nutritional deficiencies are not the most common cause of early spontaneous abortions.
