Nursing Elites

1. A client has a prescription for Amphotericin B. Which of the following laboratory values should be monitored by the nurse to assess for an adverse effect of this medication?

• A. Serum creatinine.
• B. Serum potassium.
• C. Serum sodium.
• D. Serum calcium.

Correct answer: A

Rationale: Corrected Rationale: Amphotericin B is known to cause nephrotoxicity, a potential adverse effect that can be monitored by checking the client's serum creatinine levels. Regular monitoring of serum creatinine helps in early identification of kidney damage and allows for timely intervention to prevent further complications. Choice B, serum potassium, is not typically associated with adverse effects of Amphotericin B. Choice C, serum sodium, and choice D, serum calcium, are not directly affected by Amphotericin B and are not primary indicators of its adverse effects.

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

• A. Take this medication with food.
• B. Avoid eating foods high in potassium.
• C. Take this medication at bedtime.
• D. Take this medication every other day.

Correct answer: A

Rationale: The correct instruction for taking Metformin is to take it with food. This helps reduce gastrointestinal side effects and ensures better absorption of the medication. Choice B is incorrect as there is no specific need to avoid foods high in potassium when taking Metformin. Choice C is incorrect because Metformin is usually taken with meals, not at bedtime. Choice D is incorrect as Metformin is typically taken daily, not every other day.

3. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

4. A client has a new prescription for Captopril. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid foods high in potassium.
• C. Take this medication on an empty stomach.
• D. Increase your intake of sodium-rich foods.

Correct answer: C

Rationale: Captopril should be taken on an empty stomach for better absorption. The client should be instructed to take it 1 hour before or 2 hours after meals to optimize its effectiveness. Taking it with food can reduce its absorption and efficacy.

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.
