Deck 23: Treatment of Heart Failure

Question 1

Why may furosemide lead to digoxin toxicity when prescribed together for heart failure?

A)Furosemide blocks the elimination of digoxin in that it allows for its resorption through the kidneys.
B)Furosemide deactivates the enzymes necessary to metabolize digoxin,causing digoxin toxicity.
C)Furosemide potentiates the effects of digoxin,leading to toxicity.
D)Decreased potassium levels can lead to arrhythmias,increasing the effects of digoxin.

Answer 1

Decreased potassium levels can lead to arrhythmias,increasing the effects of digoxin.
