  1. How often should AED pads be replaced when used on a victim during an extended resuscitation attempt?

    Answer: Only if the pads visibly lose adhesion or the AED prompts you to change them

    Pads should be replaced if they lose adhesion or the AED indicates a pad error; otherwise, leave them in place throughout the resuscitation.

  2. An AED delivers a shock. How long should rescuers perform CPR before the AED re-analyzes the rhythm?

    Answer: 2 minutes (5 cycles of 30:2 CPR)

    After each shock, perform 2 minutes (approximately 5 cycles of 30:2) of high-quality CPR before allowing the AED to re-analyze the rhythm.

  3. A victim of lightning strike is found unresponsive. Is it safe to use an AED?

    Answer: Yes, lightning victims do not retain electrical charge and AED use is safe and indicated

    Lightning victims do not retain electrical charge; it is safe to touch them and use an AED immediately if indicated.

  4. Which of the following BEST explains why early defibrillation significantly improves survival from cardiac arrest?

    Answer: Each minute without defibrillation in VF reduces survival by approximately 7-10%

    Survival rates from VF decrease by approximately 7-10% for every minute without defibrillation, making rapid AED use critical to survival.

  5. An AED gives a 'check pads' or 'check electrodes' message. What is the most likely cause?

    Answer: A pad is not properly adhering to the skin, has come loose, or a lead is disconnected

    A 'check pads' message typically indicates poor pad contact due to skin moisture, hair, or a disconnected cable; reposition or replace pads and reconnect leads.

  6. When using an AED in a moving vehicle (such as an ambulance), what precaution is necessary?

    Answer: Stop the vehicle before analyzing the rhythm, as motion can cause artifact and inaccurate analysis

    Vehicle motion causes artifact that can interfere with AED rhythm analysis; stop the vehicle briefly during analysis and shock delivery.

  7. A bystander who used an AED is emotionally distressed after the victim did not survive. What is the most appropriate response from a team leader?

    Answer: Reassure the bystander that they did the right thing and that AED use gave the victim the best possible chance

    Bystanders who use AEDs should be praised for acting correctly; outcomes depend on many factors beyond any single rescuer's control.
