Advanced Cardiovascular Life Support (ACLS) Practice Exam

In a patient experiencing pulseless ventricular tachycardia, following how many shocks should amiodarone be anticipated?

1. After one shock

2. After two shocks

3. After three shocks

4. After four shocks

The correct answer is: After two shocks

In cases of pulseless ventricular tachycardia (VT), the recommended guideline is to deliver up to two shocks, following which it is appropriate to administer antiarrhythmic medication such as amiodarone. Shock therapy is the first-line intervention for pulseless VT, with the primary goal being to restore a normal rhythm through defibrillation. If the patient does not respond to the initial shock, a second shock is administered. Should there still be no return of a perfusing rhythm after the second shock, the administration of amiodarone is indicated, as it can help manage the arrhythmia more effectively. This sequence—administering up to two shocks before utilizing medications—ensures that the most immediate and effective treatment options are prioritized in the resuscitation effort. Understanding this process is crucial for efficient ACLS management, where timely intervention can significantly impact patient outcomes.
