Question 1 of 5

A nurse is caring for a client who is taking digoxin to treat heart failure. Which of the following factors predisposes this client to developing digoxin toxicity?

Correct Answer: D

Rationale: The correct answer is D: Taking a high-ceiling diuretic. High-ceiling diuretics, such as furosemide, can lead to hypokalemia, which increases the risk of digoxin toxicity. Digoxin toxicity can occur due to decreased potassium levels, as digoxin competes with potassium for binding sites on the sodium-potassium pump in the heart.
Therefore, when a client taking digoxin also takes a high-ceiling diuretic that causes hypokalemia, the risk of digoxin toxicity significantly increases.

Choices A, B, and C are incorrect because they do not directly predispose the client to developing digoxin toxicity through interactions with digoxin or its mechanism of action.
