Cardiopulmonary resuscitation (CPR) is an emergency procedure designed to manually maintain blood circulation and oxygenation in a person whose heart has stopped beating or who is not breathing. It involves rhythmic chest compressions to pump blood through the body, often combined with rescue breaths to deliver oxygen. CPR is critical for sustaining vital organ function until professional medical help arrives, such as defibrillation or advanced life support. The technique can be performed by trained individuals and follows standardized guidelines, including placing the heel of one hand on the center of the chest and compressing at a rate of 100-120 compressions per minute, with a depth of at least 2 inches for adults. Early intervention with CPR can significantly improve survival rates from cardiac arrest.

Part 2: 20 cardiopulmonary resuscitation (CPR) quiz questions & answers
or
1. What is the correct compression-to-ventilation ratio for adult CPR when performing two-rescuer CPR?
A. 15:2
B. 30:2
C. 20:1
D. 10:2
Answer: B
Explanation: For adult CPR with two rescuers, the ratio is 30 chest compressions to 2 rescue breaths, allowing for effective circulation and oxygenation.
2. In which situation should CPR be started immediately without checking for a pulse?
A. A conscious adult with chest pain
B. An unresponsive adult who is not breathing normally
C. A child with a minor injury
D. An infant who is crying
Answer: B
Explanation: If an adult is unresponsive and not breathing normally, begin CPR immediately, as delays can reduce survival chances.
3. What is the recommended depth for chest compressions in an adult during CPR?
A. At least 2 inches (5 cm)
B. At least 1 inch (2.5 cm)
C. At least 3 inches (7.5 cm)
D. At least 4 inches (10 cm)
Answer: A
Explanation: Compressions should be at least 2 inches deep to effectively pump blood through the heart and to the body.
4. How should you position your hands for chest compressions on an adult?
A. On the lower half of the breastbone
B. On the upper abdomen
C. On the side of the chest
D. On the neck
Answer: A
Explanation: Place the heel of one hand on the center of the chest, on the lower half of the breastbone, to ensure compressions are effective.
5. What is the primary purpose of chest compressions in CPR?
A. To provide oxygen to the lungs
B. To maintain blood circulation to vital organs
C. To clear airway blockages
D. To monitor heart rhythm
Answer: B
Explanation: Chest compressions manually pump blood from the heart to the brain and other organs, sustaining life until advanced help arrives.
6. When performing CPR on an infant, what is the correct rate for chest compressions?
A. 100-120 per minute
B. 60-80 per minute
C. 80-100 per minute
D. 120-140 per minute
Answer: A
Explanation: The compression rate for infants is the same as for adults and children: 100-120 compressions per minute to maintain effective circulation.
7. What should you do if the airway is blocked during CPR?
A. Perform abdominal thrusts
B. Give back blows
C. Use the head-tilt, chin-lift maneuver
D. Continue compressions without interruption
Answer: C
Explanation: The head-tilt, chin-lift maneuver opens the airway; if it’s still blocked, reassess and continue CPR steps accordingly.
8. How long should you check for breathing in an unresponsive person before starting CPR?
A. Up to 10 seconds
B. Up to 1 minute
C. Up to 30 seconds
D. Up to 5 seconds
Answer: A
Explanation: Check for breathing for no more than 10 seconds to quickly determine if CPR is needed and avoid unnecessary delays.
9. What is the correct order of the CPR sequence for an adult?
A. Airway, Breathing, Compressions
B. Compressions, Airway, Breathing
C. Breathing, Compressions, Airway
D. Compressions, Airway, Defibrillation
Answer: B
Explanation: The C-A-B sequence (Compressions, Airway, Breathing) prioritizes circulation to prevent brain damage.
10. When using an AED on a child, what should you do if pediatric pads are not available?
A. Do not use the AED
B. Use adult pads if they do not touch each other
C. Wait for professional help
D. Use the pads on the back
Answer: B
Explanation: If pediatric pads are unavailable, adult pads can be used on children as long as they do not overlap, to deliver the shock safely.
11. What is the recommended rescue breath volume for an adult during CPR?
A. A full breath from your lungs
B. Just enough to make the chest rise
C. Two full breaths at once
D. No breaths, only compressions
Answer: B
Explanation: Give breaths that are just enough to make the chest rise, typically about 500-600 mL, to avoid over-inflation and gastric distension.
12. Why is it important to allow full chest recoil during CPR compressions?
A. To rest the rescuer
B. To ensure blood returns to the heart
C. To check for breathing
D. To adjust hand position
Answer: B
Explanation: Full recoil allows the heart to refill with blood between compressions, maximizing blood flow and effectiveness of CPR.
13. For how long should you continue CPR until help arrives or the person shows signs of life?
A. Until you are tired
B. For 5 minutes
C. Until emergency services take over
D. For 10 minutes
Answer: C
Explanation: Continue CPR until advanced medical help arrives, the person revives, or you are relieved by another rescuer.
14. What is a key difference in CPR for a child versus an adult?
A. Use only one hand for compressions
B. Check for a pulse for up to 60 seconds
C. The compression depth is shallower
D. Do not use an AED
Answer: C
Explanation: For children, compressions should be about one-third the depth of the chest, typically 2 inches for older children, to avoid injury.
15. What should you do if you are alone and find an unresponsive adult?
A. Start CPR immediately
B. Call for help first, then start CPR
C. Wait for witnesses
D. Check for allergies
Answer: B
Explanation: If alone, call emergency services or get an AED first, then begin CPR, to ensure help is on the way.
16. During two-rescuer CPR, how often should rescuers switch roles?
A. Every 2 minutes
B. Every 5 minutes
C. Every 1 minute
D. Never switch
Answer: A
Explanation: Switching every 2 minutes helps maintain high-quality compressions by preventing rescuer fatigue.
17. What is the first action when you arrive at a scene where someone is unresponsive?
A. Start chest compressions
B. Ensure the scene is safe
C. Give rescue breaths
D. Use an AED
Answer: B
Explanation: Check for scene safety first to protect yourself and avoid additional risks.
18. In CPR, what does the “A” in the C-A-B sequence stand for?
A. Assessment
B. Airway
C. Assistance
D. AED
Answer: B
Explanation: “A” stands for Airway, which involves opening the airway to allow for effective breathing.
19. Why should you avoid interrupting chest compressions during CPR?
A. To keep the rhythm steady
B. To allow for rest periods
C. To minimize blood flow interruptions
D. To check for pulse
Answer: C
Explanation: Interruptions reduce blood flow to vital organs, so aim for minimal pauses to improve survival rates.
20. What is the correct hand placement for CPR on an infant?
A. Two fingers on the center of the chest
B. Both hands on the abdomen
C. One hand on the chest
D. Fingers on the sides
Answer: A
Explanation: For infants, use two fingers (index and middle) on the center of the chest, just below the nipple line, for effective compressions without causing injury.
