1. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

2. When caring for a client prescribed Lithium, which laboratory value should the nurse monitor to assess for potential toxicity?

Correct answer: B

Rationale: The nurse should monitor the client's serum lithium levels to ensure they are within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels is crucial because lithium has a narrow therapeutic range, and levels outside this range can lead to toxicity, which can be life-threatening. Therefore, regular monitoring is essential to prevent adverse effects and ensure the medication's effectiveness.

3. A client has a prescription for Clonidine to treat hypertension. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: Correct Answer: Taking Clonidine at the same time each day is crucial to ensure consistent blood levels and effectively manage blood pressure. Consistency in timing helps optimize the medication's effectiveness in controlling hypertension.

4. A client has been prescribed an ACE Inhibitor for hypertension. Which of the following instructions should be included by the healthcare provider?

Correct answer: A

Rationale: The correct answer is to 'Avoid salt substitutes.' ACE Inhibitors can increase potassium levels, so clients should avoid salt substitutes that contain potassium to prevent hyperkalemia, which is a potential side effect of ACE Inhibitors. Choice B 'Take this medication at bedtime' is incorrect as ACE Inhibitors are usually taken in the morning to avoid nocturnal diuresis. Choice C 'Avoid foods high in potassium' is incorrect because although ACE Inhibitors can increase potassium levels, clients are generally encouraged to consume potassium-rich foods in moderation unless contraindicated. Choice D 'Limit your fluid intake' is also incorrect as ACE Inhibitors do not typically require fluid restrictions unless specified by a healthcare provider for other reasons.

5. When teaching a client about a new prescription for Celecoxib, which of the following information should the nurse include?

Correct answer: A

Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. Celecoxib belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Choice B is incorrect because Celecoxib does not decrease the risk of stroke. Choice C is incorrect because Celecoxib selectively inhibits COX-2 rather than COX-1. Choice D is incorrect because Celecoxib does not increase platelet aggregation; in fact, it inhibits platelet aggregation.
