A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?

A client taking furosemide for chronic hypertension.

A client taking a potassium supplement twice a day.

A client taking aluminum hydroxide for gastric upset.

A client taking chlorpropamide for type 2 diabetes mellitus.

Answer and Explanation

The Correct Answer is A

a. A client taking furosemide for chronic hypertension: Furosemide is a loop diuretic that can

lead to hypokalemia, which increases the risk of digoxin toxicity, as hypokalemia potentiates the effects of digoxin on the heart.

b. A client taking a potassium supplement twice a day: Potassium supplementation reduces the risk of digoxin toxicity, as hypokalemia is a risk factor for toxicity.

c. A client taking aluminum hydroxide for gastric upset: Aluminum hydroxide is an antacid and does not significantly affect digoxin levels.

d. A client taking chlorpropamide for type 2 diabetes mellitus: Chlorpropamide is an oral hypoglycemic agent and does not significantly affect digoxin levels.
