The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?
hypocalcemia
hypokalemia
hyperkalemia
hypernatremia
The Correct Answer is B
A. Hypocalcemia is not directly linked to digoxin toxicity; rather, it is more associated with calcium channel blockers.
B. Hypokalemia increases the risk of digoxin toxicity, as low potassium levels can enhance the effects of digoxin on the heart.
C. Hyperkalemia is not directly associated with toxicity; however, it can cause complications in patients taking digoxin.
D. Hypernatremia does not have a direct impact on digoxin toxicity; monitoring potassium levels is more critical.

B. Carvedilol is a beta-blocker used in heart failure and post-MI but is not the first choice for initial hypertension treatment.
