CPR Basic CPR Principles 1 — Questions and Answers
Question 1: What does CPR stand for?
- Cardiopulmonary Resuscitation (Correct answer)
- Cardiac Pressure Response
- Coronary Pulmonary Revival
- Cardio Pulse Restoration
Correct answer: Cardiopulmonary Resuscitation
CPR stands for Cardiopulmonary Resuscitation, a life-saving technique used when someone's heart or breathing has stopped.
Question 2: What is the primary purpose of CPR?
- To restart the heart permanently
- To maintain blood flow to vital organs until advanced care arrives (Correct answer)
- To cure cardiac arrest
- To replace a defibrillator
Correct answer: To maintain blood flow to vital organs until advanced care arrives
CPR maintains circulation and oxygenation to the brain and vital organs until emergency medical services can provide definitive treatment.
Question 3: Which organization publishes the most widely used CPR guidelines in the US?
- American Red Cross
- American Heart Association (AHA) (Correct answer)
- National Safety Council
- FEMA
Correct answer: American Heart Association (AHA)
The American Heart Association (AHA) publishes evidence-based CPR and Emergency Cardiovascular Care guidelines updated every five years.
Question 4: What is the correct sequence in the Chain of Survival for adults (out-of-hospital)?
- Call 911 → CPR → AED → Advanced care (Correct answer)
- CPR → Call 911 → AED → Advanced care
- AED → Call 911 → CPR → Advanced care
- Call 911 → Advanced care → CPR → AED
Correct answer: Call 911 → CPR → AED → Advanced care
The AHA adult out-of-hospital Chain of Survival begins with recognizing cardiac arrest and activating EMS, followed by early CPR, rapid defibrillation, and advanced care.
Question 5: What is the correct compression-to-ventilation ratio for adult CPR with a single rescuer?
- 15:2
- 30:2 (Correct answer)
- 20:2
- 5:1
Correct answer: 30:2
A single rescuer performing adult CPR should use a 30:2 ratio — 30 chest compressions followed by 2 rescue breaths.
Question 6: What is the recommended compression depth for adult CPR?
- At least 1 inch
- At least 2 inches (5 cm) (Correct answer)
- At least 3 inches
- At least 1.5 inches
Correct answer: At least 2 inches (5 cm)
Adult chest compressions should be at least 2 inches (5 cm) deep but no more than 2.4 inches (6 cm) to be effective without causing injury.
