What is the recommended rate for chest compressions during CPR for adults?
60–80 compressions per minute
B. 80–100 compressions per minute
C. 100–120 compressions per minute
D. 120–140 compressions per minute
Answer: C
Explanation: The American Heart Association (AHA) recommends performing chest compressions at a rate of 100 to 120 per minute
for adults during CPR to optimize blood flow to vital organs.
What is the correct depth of chest compressions for an adult during CPR?
About 1 inch
B. At least 2 inches
C. Approximately 3 inches
D. No more than 1.5 inches
Answer: B
Explanation: Chest compressions should be at least 2 inches (5 cm) deep to effectively pump blood through the body.
After each chest compression, you should:
Apply more pressure
B. Allow full chest recoil
C. Keep your hands in place and press harder
D. Stop and check the pulse
Answer: B
Explanation: Full chest recoil is critical because it allows the heart to refill with blood between compressions, which improves
circulation.
What is the first thing you should do when you find an unresponsive adult?
,Give two rescue breaths
B. Begin chest compressions
C. Call for help and check for breathing
D. Place the victim in a recovery position
Answer: C
Explanation: You must first check responsiveness and breathing. If the victim is unresponsive and not breathing normally, call for
help and begin CPR.
What is the correct compression-to-ventilation ratio for a single rescuer performing CPR on an adult?
15:2
B. 20:2
C. 30:2
D. 5:1
Answer: C
Explanation: For adult victims, the recommended compression-to-ventilation ratio is 30:2 when one rescuer is available.
What is the first link in the adult Chain of Survival?
High-quality CPR
B. Advanced life support
C. Early defibrillation
D. Immediate recognition of cardiac arrest
Answer: D
Explanation: Immediate recognition of cardiac arrest and activation of the emergency response system is the first step in the Chain of
Survival.
When should an AED be used?
As soon as it arrives
B. After five cycles of CPR
C. Only if the person is awake
D. Only after 2 minutes of chest compressions
,Answer: A
Explanation: The AED should be used immediately when it is available, even before completing CPR cycles.
What should you do if the AED says “shock advised”?
Remove the pads
B. Continue compressions
C. Clear the victim and deliver the shock
D. Check for breathing again
Answer: C
Explanation: Always ensure no one is touching the victim before delivering a shock to prevent accidental injury.
For infant CPR with two rescuers, what is the compression-to-breath ratio?
30:2
B. 15:2
C. 5:1
D. 10:1
Answer: B
Explanation: For infants, when two rescuers are available, the correct ratio is 15 compressions to 2 breaths.
How should you deliver breaths using a pocket mask?
Blow as hard as possible
B. Over one second, making the chest rise
C. Rapidly and forcefully
D. Without watching the chest
Answer: B
Explanation: Each breath should last about one second and make the chest visibly rise, indicating effective ventilation.
Which pulse is checked in an unresponsive adult?
, Radial pulse
B. Brachial pulse
C. Carotid pulse
D. Femoral pulse
Answer: C
Explanation: The carotid pulse is easiest and most reliable to assess in an adult during cardiac arrest.
Which action improves survival after cardiac arrest?
Delaying CPR for breathing assessment
B. Immediate defibrillation
C. Skipping compressions
D. Checking pulse every minute
Answer: B
Explanation: Immediate defibrillation significantly increases the chances of survival in shockable rhythms.
How often should rescuers switch roles during two-person CPR?
Every 5 minutes
B. After every rescue breath
C. Every 2 minutes
D. When exhausted
Answer: C
Explanation: Rescuers should switch every 2 minutes to reduce fatigue and maintain high-quality compressions.
What is the correct hand placement for adult chest compressions?
Lower abdomen
B. Upper chest
C. Center of the chest, on the lower half of the sternum
D. On the left side
Answer: C
Explanation: Compress on the lower half of the sternum, at the center of the chest.
60–80 compressions per minute
