Nursing Elites

1. A client with atrial fibrillation is prescribed warfarin (Coumadin). Which instruction should the nurse give to the client regarding lifestyle changes?

• A. Avoid prolonged sitting or standing.
• B. Use an electric razor to prevent cuts.
• C. Take your medication with a full glass of water.
• D. Eat a diet low in protein.

Correct answer: B

Rationale: The correct answer is B. Using an electric razor is advised to prevent cuts, which is crucial for individuals taking warfarin due to the increased risk of bleeding associated with this medication. Lifestyle changes related to warfarin therapy focus on minimizing the risk of bleeding, and using safety measures such as an electric razor is a practical recommendation to reduce the likelihood of injury. Choices A, C, and D are incorrect. Avoiding prolonged sitting or standing is more related to preventing blood clots than to the bleeding risk of warfarin. Taking warfarin with a full glass of water is not a specific lifestyle change associated with its use. Eating a diet low in protein is not a typical recommendation for individuals on warfarin therapy.

2. A client has a new prescription for enalapril. Which of the following instructions should the nurse include?

• A. Monitor for a dry cough.
• B. Take the medication at bedtime.
• C. Avoid consuming grapefruit juice.
• D. Take the medication with food.

Correct answer: A

Rationale: The correct answer is A: Monitor for a dry cough. When a client is prescribed enalapril, it is important to monitor for a dry cough because it can be a side effect that indicates a potential issue like angioedema. This side effect needs close attention as it may require discontinuation of the medication to prevent further complications. Choices B, C, and D are incorrect because enalapril does not need to be taken at bedtime, does not interact with grapefruit juice, and can be taken without regard to meals.

3. A client is receiving heparin therapy. Which of the following laboratory tests should be monitored to evaluate the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Complete blood count (CBC)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the most appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works on the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps assess its anticoagulant effect. Therapeutic levels of aPTT for clients on heparin therapy are typically 1.5 to 2.5 times the control value. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, which acts on the extrinsic pathway of the coagulation cascade. Complete blood count (CBC) is not specific for monitoring the effectiveness of heparin therapy.

4. A client has a new prescription for captopril. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Monitor for signs of hypokalemia.
• C. Take the medication at bedtime.
• D. Monitor for a dry cough.

Correct answer: D

Rationale: The correct answer is to monitor for a dry cough. Captopril is known to cause a persistent dry cough as a common side effect. If a dry cough develops, it should be reported to the healthcare provider promptly, as it may necessitate discontinuation of the medication. Choice A is incorrect because captopril is usually taken on an empty stomach. Choice B is incorrect as hypokalemia is not a common side effect of captopril. Choice C is incorrect as captopril is typically taken during the day and not specifically at bedtime.

5. A client has a new prescription for verapamil. Which of the following beverages should the client avoid while taking this medication?

• A. Orange juice
• B. Coffee
• C. Milk
• D. Grapefruit juice

Correct answer: D

Rationale: Grapefruit juice should be avoided while taking verapamil as it can increase drug levels and the risk of side effects. The interaction between grapefruit juice and verapamil can lead to higher concentrations of the medication in the bloodstream, potentially causing adverse effects. Orange juice, coffee, and milk do not have significant interactions with verapamil. Therefore, it is crucial for the client to avoid grapefruit juice to ensure the safe and effective use of verapamil.
