Nursing Elites

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. What should a patient avoid while taking Angiotensin-converting enzymes?

• A. Salt substitutes
• B. Foods high in potassium
• C. Foods high in sodium
• D. All of the above

Correct answer: A

Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.

3. A client has a new prescription for Metronidazole. Which of the following instructions should be included?

• A. Avoid drinking alcohol while taking this medication.
• B. Take the medication on an empty stomach.
• C. Increase your intake of green, leafy vegetables.
• D. Discontinue the medication if you experience a metallic taste.

Correct answer: A

Rationale: The correct instruction for a client prescribed Metronidazole is to avoid drinking alcohol while taking this medication. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, resulting in severe nausea, vomiting, and other adverse effects. Therefore, it is crucial for clients to refrain from consuming alcohol during treatment to prevent these potential complications. Choice B is incorrect because Metronidazole can be taken with or without food. Choice C is irrelevant as there is no specific requirement to increase green, leafy vegetable intake with Metronidazole. Choice D is incorrect as a metallic taste is a known side effect of Metronidazole but does not necessarily indicate the need to discontinue the medication.

4. A client has a new prescription for Morphine to manage post-operative pain. Which of the following assessments should the nurse perform first?

• A. Urine output
• B. Bowel sounds
• C. Pain level
• D. Respiratory rate

Correct answer: D

Rationale: The nurse should prioritize assessing the client's respiratory rate first when administering Morphine due to the risk of respiratory depression, which is a life-threatening adverse effect of this medication. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress early and take prompt action to ensure the client's safety. Assessing urine output, bowel sounds, and pain level are also important but not as critical as monitoring respiratory rate when initiating Morphine therapy.

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

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

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.
