1. Which of the following is a potassium-sparing diuretic?

• A. Furosemide
• B. Spironolactone
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

2. A healthcare professional is obtaining a medication history from a client who is to receive Imipenem-cilastatin IV to treat an infection. Which of the following medications the client also receives puts them at risk for a medication interaction?

• A. Regular insulin
• B. Furosemide
• C. Valproic acid
• D. Ferrous sulfate

Correct answer: C

Rationale: The correct answer is C, Valproic acid. Imipenem-cilastatin decreases the blood levels of valproic acid, an antiseizure medication, which can lead to increased seizure activity. Monitoring and adjusting the dosage of valproic acid may be necessary when co-administered with Imipenem-cilastatin to prevent adverse effects. Choices A, B, and D do not typically interact significantly with Imipenem-cilastatin and are not associated with a high risk of adverse interactions in this scenario.

3. A client with congestive heart failure taking digoxin refused breakfast and is complaining of nausea and weakness. Which action should the nurse take first?

• A. Check the client's vital signs.
• B. Request a consult with a dietitian.
• C. Suggest that the client rests before eating the meal.
• D. Request an order for an antiemetic.

Correct answer: A

Rationale: The nurse should check the client's vital signs first because nausea and weakness can be signs of digoxin toxicity. Vital signs can provide immediate information on the client's condition and help guide further interventions. Monitoring vital signs will allow the nurse to assess for bradycardia, a common sign of digoxin toxicity. Requesting a dietitian consult (choice B) may be necessary but addressing the immediate concern of toxicity is the priority. Suggesting rest before eating (choice C) may not address the underlying issue of digoxin toxicity. Requesting an antiemetic (choice D) can be considered later but is not the initial action needed in this situation.

4. To which pharmacologic classification does the drug propranolol belong?

• A. Beta Blockers
• B. Cholinergics
• C. Immune globulins
• D. Barbiturates

Correct answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

5. A client is taking Furosemide for heart failure. Which of the following findings is a priority to report to the provider?

• A. Weight loss of 1 kg in 24 hours
• B. Blood pressure of 104/60 mm Hg
• C. Potassium level of 3.5 mEq/L
• D. Urine output of 200 mL in 8 hours

Correct answer: D

Rationale: A urine output of 200 mL in 8 hours indicates decreased kidney function, potentially due to Furosemide therapy. This finding can suggest inadequate renal perfusion and impaired drug clearance, necessitating immediate reporting to prevent further complications like electrolyte imbalances and worsening heart failure. Choice A: Weight loss may be expected in heart failure patients due to fluid retention, but it is not an immediate concern. Choice B: A blood pressure of 104/60 mm Hg is slightly low but not a priority compared to the indication of kidney dysfunction. Choice C: A potassium level of 3.5 mEq/L is within the normal range, so it does not require immediate reporting.
