FISDAP EMT Readiness Practice Test

When an Automated External Defibrillator (AED) indicates that a shock is advised for a patient in cardiac arrest, it is crucial to administer that shock. The AED is designed to analyze the heart's rhythm and determine whether defibrillation is necessary. If the device prompts for a shock, it means that the patient's heart is in a rhythm that is shockable, such as ventricular fibrillation or pulseless ventricular tachycardia.

Delivering the shock can potentially restore a normal heart rhythm and may help save the patient's life. Once the shock is administered, you should immediately follow it up with high-quality CPR unless the AED indicates otherwise. The emphasis at this moment is on responding to the AED’s guidance because it is programmed with protocols based on current life support guidelines.

In contrast, waiting for medical assistance, performing CPR instead without delivering the shock, or re-assessing the airway without following through with the AED’s recommendation would delay critical intervention, which is detrimental in a cardiac arrest scenario. Therefore, adhering to the AED's instructions is paramount to maximizing the chances of survival.
