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 patient is prescribed acetaminophen 650 mg PO every 6 hr PRN for pain. The available acetaminophen liquid is 500 mg/5 mL. How many mL should the nurse administer per dose?

• A. 6.5 mL
• B. 7 mL
• C. 5 mL
• D. 8 mL

Correct answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen. Choice B, 7 mL, is incorrect because the correct calculation results in 6.5 mL. Choice C, 5 mL, is incorrect as it is the concentration of the acetaminophen liquid, not the final volume needed. Choice D, 8 mL, is incorrect because it does not reflect the accurate calculation based on the prescription and concentration.

3. A client who has been taking prednisone to treat asthma is advised to discontinue the medication. The client should be instructed to reduce the dose gradually to prevent which of the following adverse effects?

• A. Hyperglycemia
• B. Adrenocortical insufficiency
• C. Severe dehydration
• D. Rebound pulmonary congestion

Correct answer: B

Rationale: Abruptly stopping prednisone can result in adrenocortical insufficiency due to suppression of the adrenal glands. Gradually tapering the dose helps the body adjust and resume its natural cortisol production, preventing adrenal insufficiency. Choice A, hyperglycemia, is a possible adverse effect of prednisone, but it is not the primary reason for gradual tapering. Severe dehydration (Choice C) and rebound pulmonary congestion (Choice D) are not typically associated with discontinuing prednisone.

4. When educating a client who has a new prescription for Hydrochlorothiazide, which of the following statements should the nurse include?

• A. Take this medication in the morning.
• B. You may need to increase your intake of potassium.
• C. This medication may cause drowsiness.
• D. Avoid consuming grapefruit.

Correct answer: B

Rationale: The correct statement to include when educating a client with a new prescription for Hydrochlorothiazide is that they may need to increase their intake of potassium. Hydrochlorothiazide is a thiazide diuretic that can lead to potassium loss. Monitoring potassium levels and increasing potassium intake if necessary can help prevent complications associated with hypokalemia. Option A is not directly related to the medication's specific instructions. Option C is incorrect as Hydrochlorothiazide typically does not cause drowsiness. Option D is unrelated, as there is no interaction between Hydrochlorothiazide and grapefruit.

5. A client has a new prescription for Metronidazole to treat an infection. Which of the following instructions should the nurse include?

• A. Avoid alcohol while taking this medication.
• B. Take this medication on an empty stomach.
• C. Increase your intake of dairy products while taking this medication.
• D. Avoid direct sunlight while taking this medication.

Correct answer: A

Rationale: The correct instruction is to avoid alcohol while taking Metronidazole. This is crucial to prevent a disulfiram-like reaction, which can result in severe nausea and vomiting. Alcohol should be avoided for at least 48 hours after completing the medication course as well. Choice B is incorrect because Metronidazole can be taken with food to reduce gastrointestinal side effects. Choice C is incorrect because there is no need to increase dairy product intake while on Metronidazole. Choice D is incorrect because there is no specific instruction to avoid direct sunlight while taking this medication.
