CPR AED Advanced 3 — Questions and Answers
Question 1: A patient has a transdermal medication patch on the upper right chest where a pad should go. What is correct?
- Remove the patch and wipe the area before applying the pad (Correct answer)
- Place the pad directly over the patch
- Leave the patch and skip that pad
- Apply the pad next to the patch without removing it
Correct answer: Remove the patch and wipe the area before applying the pad
Medication patches can cause burns and block current, so remove the patch and clean the skin first.
Question 2: An adult patient has a very hairy chest preventing pad adhesion. What is the best response?
- Press pads firmly, and if they won't stick, quickly shave or trim the area (Correct answer)
- Apply pads loosely and shock anyway
- Pour water on the chest to help pads stick
- Abandon AED use
Correct answer: Press pads firmly, and if they won't stick, quickly shave or trim the area
Poor pad contact reduces shock effectiveness, so press firmly or rapidly shave the contact areas.
Question 3: What is the recommended maximum interruption in chest compressions when delivering an AED shock?
- Keep the pause as short as possible, ideally under 10 seconds (Correct answer)
- About 30 seconds
- One full minute
- Two minutes
Correct answer: Keep the pause as short as possible, ideally under 10 seconds
Minimizing the peri-shock pause maintains coronary perfusion and improves survival.
Question 4: Immediately after the AED delivers a shock, what should rescuers do?
- Resume chest compressions right away without checking a pulse (Correct answer)
- Check the pulse for 30 seconds
- Wait for the AED to reanalyze before any action
- Remove the pads
Correct answer: Resume chest compressions right away without checking a pulse
Guidelines call for immediate resumption of compressions after a shock to support circulation.
Question 5: How often does a standard AED typically prompt to reanalyze the rhythm during resuscitation?
- About every 2 minutes (after each cycle of CPR) (Correct answer)
- Every 30 seconds
- Every 10 minutes
- Only once at the start
Correct answer: About every 2 minutes (after each cycle of CPR)
The AED reanalyzes roughly every two minutes, matching the standard CPR cycle.
Question 6: A patient is on a metal stretcher when arrest occurs. What is the safest action before shocking?
- Ensure no rescuer is touching the metal and that the patient is not contacting others (Correct answer)
- Shock without any precautions
- Ground the stretcher to a wall
- Move the patient onto a wooden floor only
Correct answer: Ensure no rescuer is touching the metal and that the patient is not contacting others
The shock follows the path between pads; ensure no one is in contact so current is not transmitted to bystanders.
Question 7: Why is it important to attach the AED pads to bare skin rather than over clothing?
- Clothing prevents proper electrical contact and shock delivery (Correct answer)
- Clothing improves conductivity
- Pads are designed to work through fabric
- It only affects pad comfort
Correct answer: Clothing prevents proper electrical contact and shock delivery
Pads must contact bare, dry skin to deliver the shock effectively.
