A client is prescribed spironolactone. Which of the following findings would indicate an adverse effect of this medication?

A. Hyperkalemia

B. Hypokalemia

C. Hyponatremia

D. Hypernatremia

Correct Answer: A
Rationale: Hyperkalemia is the correct answer as it is an adverse effect associated with spironolactone, a potassium-sparing diuretic. Spironolactone works by blocking the aldosterone receptor in the distal convoluted tubule, leading to decreased potassium excretion and potential hyperkalemia. Hypokalemia (choice B) and hyponatremia (choice C) are not typically associated with spironolactone use. Hypernatremia (choice D) is also an unlikely finding with spironolactone.

A nurse is caring for a client newly prescribed doxazosin mesylate. Which of the following instructions should the nurse include in client education regarding taking the first dose of this medication?

• A. Change positions slowly and lie down if dizziness occurs
• B. There is no need to avoid normal activities
• C. Avoid dairy products while taking this medication
• D. Do not eat green leafy vegetables

Correct Answer: A
Rationale: Corrected Rationale: First-dose orthostatic hypotension can occur with doxazosin. The nurse should advise the client to change positions slowly and lie down if dizziness occurs. Choice B is incorrect because it does not address the potential side effect of dizziness. Choice C and D are also incorrect as there is no specific dietary restriction related to doxazosin mesylate.

A nurse is preparing to administer metoprolol to a client with hypertension. Which of the following should the nurse assess prior to administering this medication?

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

Correct Answer: D
Rationale: The correct answer is D: Blood pressure. Before administering metoprolol, a beta-blocker commonly used to treat hypertension, the nurse should assess the client's blood pressure. Metoprolol works by lowering blood pressure and reducing the workload on the heart. Assessing the blood pressure is crucial to ensure it is within the acceptable range to administer the medication safely. Choices A, B, and C (Temperature, Heart rate, Respiratory rate) are important assessments in general patient care but are not specifically required before administering metoprolol for hypertension.

A nurse is caring for a client prescribed digoxin. Which of the following should alert the nurse to possible digitalis toxicity?

• A. Anorexia and weakness
• B. Hyperactivity and hunger
• C. Tachycardia and increased urination
• D. Polyphagia and polydipsia

Correct Answer: A
Rationale: The correct answer is A: Anorexia and weakness. These symptoms are early indicators of potential digitalis toxicity. Anorexia refers to a loss of appetite, which can be a sign of toxicity, and weakness can indicate an issue with digoxin. Choices B, C, and D are incorrect. Hyperactivity and hunger, tachycardia and increased urination, as well as polyphagia and polydipsia are not typically associated with digitalis toxicity.

A client is receiving chemotherapy and develops stomatitis. Which of the following interventions should the nurse include in the client's plan of care?

• A. Apply warm compresses to the mouth
• B. Rinse mouth with alcohol-free mouthwash
• C. Increase fluid intake
• D. Clean the mouth gently with a soft toothbrush after meals

Correct Answer: A
Rationale: The correct answer is to apply warm compresses to the mouth. Stomatitis is an inflammation of the mucous lining in the mouth and can be a side effect of chemotherapy. Warm compresses can help soothe the affected area and promote healing. Choice B is incorrect because alcohol-based mouthwash can further irritate the mouth. Choice C is also a good intervention as increasing fluid intake can help keep the mouth moist and promote healing. However, the most direct intervention for soothing and healing the affected area is applying warm compresses. Choice D is incorrect because using a firm toothbrush can be too harsh and cause further irritation.
