Question 1 of 5
A nurse is caring for a client who has a life-threatening ventricular dysrhythmia. Which of the following medications should the nurse anticipate administering?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. Amiodarone is an antiarrhythmic medication commonly used to treat life-threatening ventricular dysrhythmias. It works by prolonging the action potential duration and refractory period of cardiac muscle cells, thereby stabilizing the heart's electrical activity. Digoxin (
A) is not typically used for ventricular dysrhythmias. Dopamine (
B) is a vasopressor used for hypotension, not dysrhythmias. Verapamil (
C) is a calcium channel blocker, which is contraindicated in ventricular dysrhythmias.
Therefore, the nurse should anticipate administering amiodarone to treat the client's life-threatening ventricular dysrhythmia.
