BLS Automated External Defibrillator (AED) Use 2

Question 1

A victim is found in a pool of water. What should you do before using an AED?

Accepted Answer

Move the victim to a dry surface and dry the chest

Answer

The victim must be moved to a dry surface and the chest dried before AED pads are applied to prevent shock conduction through water.

Question 2

An AED analyzes the heart rhythm and advises 'No shock recommended.' What is the correct next action?

Accepted Answer

Resume CPR immediately, starting with chest compressions

Answer

If no shock is advised, resume CPR immediately beginning with chest compressions, as the rhythm may be non-shockable (e.g., PEA or asystole).

Question 3

Which of the following best describes the purpose of the AED's rhythm analysis phase?

Accepted Answer

To determine if a shockable rhythm such as VF or pulseless VT is present

Answer

The AED analyzes the cardiac rhythm to detect shockable rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT).

Question 4

You are using an AED on an adult victim and notice significant chest hair. What should you do?

Accepted Answer

Shave the chest if a razor is available, or press pads firmly and remove quickly to clear hair, then reapply

Answer

Excess chest hair can prevent good pad contact; quickly shaving or using a pad to strip hair improves electrode adhesion for accurate analysis and effective shock delivery.

Question 5

After delivering a shock with the AED, what is the immediate next step?

Accepted Answer

Resume CPR beginning with chest compressions

Answer

Immediately after a shock, resume CPR starting with chest compressions without pausing to check for a pulse.
