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.

Correct Answer is D

Explanation

a. Eating dinner early in the evening: Eating dinner early can actually be a positive factor in preventing heartburn by allowing more time for digestion before lying down.

b. Sleeping on a large wedge-style pillow: Elevating the upper body can help prevent acid reflux, so sleeping on a wedge-style pillow may be a helpful strategy.

c. Consuming low-fat meats: Low-fat meats are less likely to contribute to heartburn compared to high-fat meats.

d. Drinking orange juice regularly: Orange juice is acidic and can contribute to heartburn,

especially if consumed regularly. The acid content can irritate the esophagus and worsen GERD symptoms.

A. Decreased calcium level B. Decreased potassium level C. Elevated magnesium level D. Elevated sodium level

Correct Answer is B

Explanation

a. Decreased calcium level: NG tube drainage is more likely to result in hypokalemia (decreased potassium) than hypocalcemia (decreased calcium).

b. Decreased potassium level: NG tube drainage, which contains stomach contents, can lead to loss of potassium. Monitoring for hypokalemia is crucial as it can result in cardiac dysrhythmias.

c. Elevated magnesium level: NG tube drainage is not typically associated with an increase in magnesium levels.

d. Elevated sodium level: NG tube drainage may contribute to sodium loss, leading to hyponatremia, rather than hypernatremia.
