When used by a trained person a(n) ________ device may be used to restart the heart and save an individual's life.

• A. AED (automatic electrical defibrillator)
• B. CPR mask
• C. Stethoscope
• D. Blood pressure cuff

Answer: (A)

The device used by a trained person to restart the heart and save a life is an AED, automated external defibrillator. In sudden cardiac arrest, delivering a controlled electric shock can reset the heart’s electrical rhythm and restore a viable heartbeat, which is why AEDs are designed to be quick, guided tools for responders. They analyze the heart rhythm and prompt the user to deliver a shock only when appropriate, which helps maximize survival. Other tools listed have valuable roles in emergencies—CPR masks assist with delivering breaths, a stethoscope is for listening to heart and lung sounds, and a blood pressure cuff measures pressure—but none of them restart the heart.
