Nursing Elites

1. A healthcare provider is caring for a client who is prescribed Digoxin. Which of the following laboratory values should the provider monitor to assess for potential toxicity?

• A. Sodium
• B. Potassium
• C. Magnesium
• D. Calcium

Correct answer: B

Rationale: The correct answer is to monitor the client's potassium levels. Hypokalemia can increase the risk of Digoxin toxicity. Potassium levels should be closely monitored to prevent adverse effects. Monitoring sodium levels is not directly related to Digoxin toxicity. While magnesium and calcium are important electrolytes, potassium levels are more critical for Digoxin toxicity assessment.

2. A client has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?

• A. I will avoid eating large amounts of green leafy vegetables.
• B. I will take my medication at the same time every day.
• C. I will increase my intake of foods high in potassium.
• D. I will report any signs of bleeding to my provider.

Correct answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.

3. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

• A. aPTT
• B. Platelet count
• C. BUN
• D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

4. A client has a new prescription for spironolactone. The nurse should instruct the client to avoid which of the following foods?

• A. Salt substitutes
• B. Apples
• C. Chicken
• D. Bananas

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic. The client should avoid salt substitutes because they often contain potassium, which could lead to hyperkalemia. Hyperkalemia, or high levels of potassium in the blood, is a potential side effect of spironolactone, and ingesting additional potassium from salt substitutes can exacerbate this risk.

5. A client is starting therapy with Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Tachycardia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypertension

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect due to its mechanism of action in slowing down the heart rate. The nurse should instruct the client to monitor their pulse regularly and report any significant decreases to prevent complications related to bradycardia.
