• D. A device to deliver oxygen

Answer: (C)

An AED is an Automated External Defibrillator, a device used in sudden cardiac arrest to restore a normal heart rhythm by delivering an electrical shock when the device determines a shock is needed. It analyzes the heart's rhythm and guides you through the steps with voice prompts, making it usable by bystanders with minimal training. Use it as soon as possible when a person is unresponsive and not breathing normally, after calling emergency services and starting CPR if you’re able. Turn on the unit, place the pads as shown, make sure no one is touching the person during analysis or shock, and follow the prompts. If a shock is advised, deliver it and then continue CPR as directed until professional help arrives. This tool is for sudden cardiac arrest, not for other conditions like a non-arrest heart attack or fainting without a shockable rhythm.
