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. A client received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min, and blood pressure is 74/44 mm Hg. The nurse should anticipate a prescription for which of the following IV medications?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Magnesium sulfate

Correct answer: A

Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels. Sodium bicarbonate is not indicated for low blood pressure. Potassium chloride and magnesium sulfate are not the appropriate choices to address hypotension caused by Verapamil.

3. A client informs the nurse about taking Gingko Biloba. Which of the following medications is contraindicated for a client taking Gingko Biloba?

• A. Acetaminophen
• B. Warfarin
• C. Digoxin
• D. Lisinopril

Correct answer: B

Rationale: The correct answer is B, Warfarin. Warfarin is contraindicated for a client taking Gingko Biloba due to the potential interaction. Gingko Biloba can suppress coagulation and increase the risk of bleeding or hemorrhage when taken with anticoagulants like Warfarin. Acetaminophen (choice A), Digoxin (choice C), and Lisinopril (choice D) do not have significant interactions with Gingko Biloba.

4. When starting therapy with Lisinopril, a client should be instructed to monitor for which of the following adverse effects?

• A. Tinnitus
• B. Diarrhea
• C. Cough
• D. Weight gain

Correct answer: C

Rationale: When starting therapy with Lisinopril, a client should be instructed to monitor for a persistent dry cough as an adverse effect. Lisinopril, an ACE inhibitor, commonly causes this cough as an adverse effect. It is important for the client to monitor for this symptom and notify their healthcare provider if it occurs. Choices A, B, and D are incorrect because tinnitus, diarrhea, and weight gain are not commonly associated adverse effects of Lisinopril.

5. A healthcare professional reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the professional take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication, and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments. Choice B is incorrect because waiting 24 hours after taking the medication would not provide an accurate trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect because obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level, as it is the lowest concentration before the next dose.
