Question

In which of the following scenarios should an Automated External Defibrillator (AED) be used?

Options

AConscious or unconscious client with shortness of breath
BUnconscious client with a pulse
CConscious client with chest pain
DUnconscious client without a pulse

Explanation

An AED is indicated only when a victim is in cardiac arrest, which is defined as unconsciousness without a pulse, indicating a shockable cardiac rhythm such as ventricular fibrillation.

Common mistakes.

A. Shortness of breath with or without consciousness is a respiratory complaint, not a cardiac arrest indication - AED use requires confirmed pulselessness.
B. A client who is unconscious but has a pulse is not in cardiac arrest; applying an AED shock to a beating heart is dangerous and not indicated.
C. A conscious client, regardless of symptoms, has a functioning heartbeat by definition - AED use is never appropriate in a conscious person.

Concept tested. AED indications for cardiac arrest - pulseless victim
