What is the AED use guideline for children?

• A. Only if age is at least 8 years or weight at least 55 pounds.
• B. AEDs are never used on children.
• C. Only after adult uses the device.
• D. AED use is optional for all minors.

Answer: (A)

The main idea being tested is how size affects when you apply an AED to a child. Defibrillator use for kids is guided by body size because pad placement and energy levels are chosen to match the smaller chest and heart of a child.

The option reflects a straightforward size-based rule: treat a child with an AED if they are at least eight years old or weigh about 55 pounds. This threshold corresponds to when the device’s standard pediatric settings become appropriate for a child of that size, helping ensure the energy delivered is effective without posing undue risk to a smaller child. In a real emergency, smaller children typically have access to pediatric pads or adjusted energy, but this rule gives a clear, quick criteria for deciding to use the device.

Other choices imply you should never use an AED on children, wait for an adult to start, or treat it as optional for minors. These ideas would delay potentially life-saving treatment, which isn’t consistent with the urgency of cardiac arrest care. In any case, always follow the device’s instructions and your training, and use pediatric pads or adjust energy as available.
