First Aid CPR and AED Procedures 4 — Questions and Answers
Question 1: A victim is wearing a transdermal medication patch on their chest. What should you do before applying AED pads?
- Apply the AED pad directly over the patch
- Remove the patch with a gloved hand and wipe the area dry (Correct answer)
- Use only the back pad and skip the chest pad
- Choose a different defibrillator type
Correct answer: Remove the patch with a gloved hand and wipe the area dry
Medication patches can block electrical delivery and cause burns; remove them with a gloved hand and wipe the skin before applying pads.
Question 2: When performing hands-only CPR, you should push hard and fast at a rate of:
- 60–80 compressions per minute
- 80–100 compressions per minute
- 100–120 compressions per minute (Correct answer)
- 120–140 compressions per minute
Correct answer: 100–120 compressions per minute
The recommended compression rate is 100–120 compressions per minute for effective hands-only CPR.
Question 3: After delivering a shock with the AED, what is the IMMEDIATE next step?
- Check for a pulse
- Wait for the AED to re-analyze
- Resume CPR starting with chest compressions (Correct answer)
- Apply supplemental oxygen
Correct answer: Resume CPR starting with chest compressions
After a shock, immediately resume CPR starting with chest compressions without checking the pulse first.
Question 4: A victim is lying on a wet surface. How should this affect AED use?
- Do not use the AED on a wet surface under any circumstances
- Move the victim to a dry surface before using the AED (Correct answer)
- Use the AED as normal; water does not affect shocks
- Only use the AED if the victim is completely dry all over
Correct answer: Move the victim to a dry surface before using the AED
Move the victim to a dry surface before attaching AED pads to prevent electrical conduction through water.
Question 5: During CPR, you must allow full chest recoil between compressions because:
- It prevents rib fractures
- It allows the heart to refill with blood (Correct answer)
- It gives the victim time to breathe
- It reduces rescuer fatigue
Correct answer: It allows the heart to refill with blood
Full chest recoil allows negative pressure to draw blood back into the heart, enabling effective circulation.
Question 6: A bystander has been performing CPR alone for 5 minutes. You arrive with an AED. What is the FIRST thing you should do?
- Turn on the AED and attach pads immediately, pausing CPR
- Tell the bystander to stop and check for a pulse
- Have the bystander continue CPR while you set up the AED (Correct answer)
- Perform 2 minutes of CPR yourself before using the AED
Correct answer: Have the bystander continue CPR while you set up the AED
Minimize interruptions to CPR by having the bystander continue compressions while you prepare and attach the AED.
Question 7: Which of the following situations requires a jaw-thrust maneuver instead of head-tilt chin-lift to open the airway?
- Victim is obese
- Victim has a suspected spinal injury (Correct answer)
- Victim has dentures
- Victim is a child under 8
Correct answer: Victim has a suspected spinal injury
A jaw-thrust maneuver is used when a spinal injury is suspected to open the airway without moving the neck.
