In cardiac arrest due to ventricular fibrillation, what is the priority action?

Explanation:
In ventricular fibrillation the heart’s electrical activity is chaotic and it cannot pump blood, so there’s no effective circulation. The priority is to deliver a defibrillating shock as quickly as possible because defibrillation can terminate the chaotic rhythm and allow the heart’s normal conduction system to resume a usable rhythm. Survival is highest when defibrillation occurs early, so once a defibrillator is ready, shock promptly and then resume high-quality CPR and follow the device prompts. Other actions like addressing pain or monitoring blood pressure don’t restore circulation in this moment and aren’t the immediate focus during an arrest.
