A patient taking hydrochlorothiazide is also prescribed digoxin. Which lab value should the nurse monitor closely?
Sodium
Magnesium
Calcium
Potassium
The Correct Answer is D
(A) Sodium: Thiazide diuretics can lower sodium, but hyponatremia does not directly affect digoxin toxicity.
(B) Magnesium: Magnesium is important for cardiac function but not as directly linked to digoxin toxicity as potassium.
(C) Calcium: Thiazides can cause hypercalcemia, but calcium does not significantly affect digoxin toxicity.
(D) Potassium: Thiazide diuretics (e.g., hydrochlorothiazide) cause potassium loss, which increases the risk of digoxin toxicity. Hypokalemia sensitizes the heart to digoxin’s effects, leading to arrhythmias.
