Question 1 of 5
A client has been diagnosed with a life-threatening recurrent ventricular fibrillation that has not responded to other medications or defibrillation. Which of the following does the nurse anticipate will be prescribed next?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. This medication is used to treat life-threatening ventricular arrhythmias like ventricular fibrillation that have not responded to other treatments. Amiodarone works by prolonging the action potential and refractory period of cardiac tissue, helping to stabilize the heart's rhythm. Quinidine (
A) is not typically used for ventricular arrhythmias. Digoxin (
B) is used for heart failure and atrial fibrillation, not ventricular fibrillation. Atropine (
C) is used for bradycardia, not ventricular fibrillation. Amiodarone is the drug of choice for this situation.
