Nursing Elites

1. A client has a prescription for furosemide. Which of the following instructions should the nurse include?

• A. Take furosemide in the morning.
• B. Eat a diet high in potassium.
• C. Avoid foods high in magnesium.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.

2. Which of the following conditions is not treated with Dexamethasone?

• A. Inflammation
• B. Asthma
• C. Addison’s disease
• D. Wilson’s disease

Correct answer: D

Rationale: Dexamethasone is not used to treat Wilson’s disease. It is a corticosteroid primarily used for conditions like inflammation, asthma, and Addison’s disease. Wilson’s disease is a genetic disorder involving copper accumulation and is treated with medications like chelating agents or zinc salts, not Dexamethasone.

3. Potassium-sparing diuretics primarily affect which part of the kidney?

• A. Proximal convoluted tubule
• B. Loop of Henle
• C. Collecting duct
• D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

4. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?

• A. Naloxone
• B. Vitamin K
• C. Digibind
• D. Flumazenil

Correct answer: C

Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.

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

• A. Drink 2 liters of water daily.
• B. Avoid taking the medication on an empty stomach.
• C. Limit vitamin C intake while taking this medication.
• D. Take an iron supplement while on this medication.

Correct answer: A

Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This helps reduce the risk of kidney stones, a potential side effect of allopurinol use. Adequate hydration is essential to prevent kidney stone formation and maintain kidney function while taking this medication.
