Nursing Elites

1. 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.

2. A healthcare professional is preparing to administer Diltiazem IV to a client who has atrial fibrillation. Which of the following findings should the healthcare professional report immediately?

• A. Bradycardia.
• B. Hypertension.
• C. Shortness of breath.
• D. Tachycardia.

Correct answer: A

Rationale: The correct answer is bradycardia. Diltiazem, a calcium channel blocker, can lead to bradycardia as a side effect. Bradycardia should be reported immediately because it can result in serious cardiac complications, especially in a client with atrial fibrillation. Hypertension, shortness of breath, and tachycardia are not typically associated with Diltiazem administration and would not be immediate concerns in this scenario.

3. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?

• A. Apply the patch to a different site each day.
• B. Remove the patch at bedtime each day.
• C. Apply the patch over an area with little or no hair.
• D. Keep the patch on for 24 hours at a time.

Correct answer: B

Rationale: The correct instruction for a client using a Nitroglycerin transdermal patch is to remove the patch each day, usually at bedtime, to prevent tolerance. This practice allows for a nitrate-free interval, reducing the risk of developing tolerance to the medication. Applying the patch to a different site each day (choice A) is not necessary as long as the skin is clean and rotated to avoid skin irritation. Applying the patch over an area with little or no hair (choice C) does not impact the effectiveness of the medication. Keeping the patch on for 24 hours at a time (choice D) can lead to tolerance, which is why the patch should be removed daily.

4. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?

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

Correct answer: B

Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.

5. A client has anemia and a new prescription for ferrous sulfate liquid. Which of the following instructions should the nurse provide?

• A. Take the medication on an empty stomach to decrease gastrointestinal irritation.
• B. Take the medication with orange juice to enhance absorption.
• C. Take the medication with milk.
• D. Rinse the mouth before taking the iron.

Correct answer: B

Rationale: Taking ferrous sulfate with orange juice can help increase the absorption of iron. Orange juice contains vitamin C, which aids in the absorption of iron from the medication. This combination can enhance the effectiveness of the iron supplement for a client with anemia. Option A is incorrect because taking iron on an empty stomach can cause gastrointestinal upset. Option C is incorrect because calcium in milk can inhibit iron absorption. Option D is irrelevant to enhancing iron absorption.
