Nursing Elites

1. A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?

• A. Take the medication at the same time each day.
• B. Avoid foods high in potassium.
• C. Skip a dose if you feel well.
• D. Take the medication on an empty stomach.

Correct answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm. Choices B, C, and D are incorrect because avoiding potassium-rich foods, skipping doses when feeling well, and taking the medication on an empty stomach are not relevant or appropriate instructions for a client prescribed digoxin.

2. 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.

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

• A. Take the medication with food.
• B. Increase your fluid intake.
• C. Avoid consuming dairy products.
• D. Take the medication in the morning.

Correct answer: B

Rationale: Increasing fluid intake is essential when taking allopurinol to prevent the formation of kidney stones. Allopurinol can increase the levels of uric acid in the body, which can lead to kidney stone formation. By increasing fluid intake, the client can help flush out excess uric acid and prevent the development of kidney stones. It is important to drink plenty of water throughout the day to maintain adequate hydration and reduce the risk of kidney stone formation. Choices A, C, and D are incorrect. Taking allopurinol with food or in the morning does not specifically relate to preventing kidney stone formation. Avoiding dairy products is not a standard recommendation when taking allopurinol.

4. The nurse is preparing to administer a scheduled dose of enalapril (Vasotec) to a client with hypertension. Before administering the medication, the nurse should check which priority assessment?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Temperature

Correct answer: B

Rationale: Before administering enalapril, an antihypertensive medication, the nurse should prioritize checking the client's blood pressure. Monitoring blood pressure helps ensure it is at an acceptable level before giving the medication, as enalapril can further lower blood pressure. This assessment is crucial in preventing potential hypotensive episodes and adverse effects associated with excessive blood pressure reduction. Heart rate, respiratory rate, and temperature are important assessments but are not the priority before administering enalapril, which primarily affects blood pressure levels.

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

• A. Take the medication with a full glass of water.
• B. Avoid consuming dairy products.
• C. Take the medication on an empty stomach.
• D. Expect a metallic taste in your mouth.

Correct answer: B

Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.
