In the event of pulseless ventricular fibrillation, what is the initial and most critical nursing intervention to maximize the chance of survival?

Correct answer: Performing high-quality cardiopulmonary resuscitation (CPR).

Explanation

This question emphasizes the time-critical nature of responding to a cardiac arrest. The immediate initiation of high-quality CPR is the single most important intervention to improve survival outcomes in ventricular fibrillation.
