A patient develops pulseless ventricular fibrillation that persists after CPR and defibrillation. Which antiarrhythmic drug should the nurse prepare according to the cardiac arrest protocol?
Correct answer: A. Amiodarone
- A. Amiodarone
- B. Adenosine
- C. Verapamil
- D. Digoxin
Explanation
Amiodarone is used for shock-refractory ventricular fibrillation or pulseless ventricular tachycardia during cardiac arrest. Adenosine and verapamil treat selected supraventricular rhythms, while digoxin does not treat this arrest rhythm.
