Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: 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.

2. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

3. 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?

• A. Reassess the pain and its characteristics
• B. Administer prescribed pain medication
• C. Notify the surgeon
• D. Encourage the use of relaxation techniques

Correct answer: A

Rationale: 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.

4. The nurse is caring for a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct answer: D

Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.

5. A client with a urinary tract infection is prescribed antibiotics. What should the nurse inform the client about antibiotic therapy?

• A. It may interfere with oral contraceptive effectiveness
• B. It can cause drowsiness
• C. It should be taken with meals
• D. Completing the full course is crucial

Correct answer: D

Rationale: Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. Informing the client about the importance of finishing the prescribed course helps in ensuring the effectiveness of the treatment and reduces the risk of recurrence. Choice A is incorrect because antibiotics do not generally interfere with oral contraceptive effectiveness. Choice B is incorrect because drowsiness is not a common side effect of antibiotics. Choice C is incorrect because while some antibiotics may need to be taken with meals, it is not a universal rule for all antibiotics.
