Which item is described as a handheld device that almost anyone can be trained to use to treat life-threatening heart rhythms?

• A. Portable blood glucose monitor
• B. Epinephrine auto-injector
• C. Ventolin inhaler
• D. Automated External Defibrillator

Answer: (D)

The main idea being tested is identifying a handheld device that bystanders can be trained to use to treat life-threatening heart rhythms. An automated external defibrillator is designed for exactly that purpose. It’s portable and provides simple, guided instructions with voice prompts. It analyzes the heart’s rhythm and delivers a shock when a life-threatening rhythm like ventricular fibrillation or pulseless ventricular tachycardia is detected, all in a way that someone with minimal training can operate. This public-access device is meant to be used quickly in sudden cardiac arrest to restore normal rhythm and improve chances of survival. Other items serve different medical needs—for example, a portable blood glucose monitor tracks blood sugar, an epinephrine auto-injector treats severe allergic reactions, and a Ventolin inhaler relieves asthma symptoms. None of these restore heart rhythm, so they don’t fit the scenario described.
