1. How many components does Basic Life Support CPR consist of?
A. 1
B. 2
C. 3
D. 4
Correct Answer – C
Rationale – Basic Life Support CPR consists of three core components: Circulation, Airway, and
Breathing (C-A-B).
2. In what order is the Basic Life Support CPR administered?
A. Breathing, Airway, Circulation
B. Airway, Breathing, Circulation
C. Circulation, Breathing, Airway
D. Circulation, Airway, Breathing
Correct Answer – D
Rationale – The sequence for BLS CPR is Circulation (chest compressions), then Airway (open
the airway), then Breathing (provide rescue breaths).
,3. Which of the following best describes the first link in the out-of-hospital adult Chain of
Survival?
A. Early CPR
B. Early access
C. Early defibrillation
D. Early advanced care
Correct Answer – B
Rationale – The first link is early access, which involves establishing unresponsiveness and then
activating EMS/911.
4. What is the first action you should take for a conscious adult victim who is choking?
A. Begin abdominal thrusts immediately
B. Ask if they are choking
C. Call 911
D. Perform back blows
Correct Answer – B
Rationale – For a conscious choking adult, the first step is to ask if they are choking to confirm
the situation before offering help.
5. What is your first course of action for an unconscious adult victim who is choking?
A. Perform abdominal thrusts
B. Call 911
C. Start CPR, beginning with chest compressions
D. Look in the mouth and remove the object if seen
,Correct Answer – B
Rationale – For an unconscious choking victim, the first step is to call 911 to activate the
emergency response system.
6. When is rescue breathing performed for an adult victim?
A. When the victim is not breathing and has no pulse
B. When the victim is not breathing adequately but has a pulse
C. When the victim is gasping for air
D. When the victim is unconscious for any reason
Correct Answer – B
Rationale – Rescue breathing is indicated when a victim has a pulse but is not breathing
adequately.
7. What is the correct timing for rescue breaths for an adult victim?
A. 1 breath every 3-5 seconds
B. 1 breath every 5-6 seconds
C. 1 breath every 10 seconds
D. 2 breaths every 5 seconds
Correct Answer – B

seconds, which equates to 10-12 breaths per minute.
8. Which of the following best describes "inadequate breathing" in an adult victim?
A. Rapid, shallow breathing
B. Agonal gasps instead of normal breaths
, C. Breathing at a rate of 20 breaths per minute
D. Noisy breathing
Correct Answer – B
Rationale – Agonal gasps are ineffective and are not considered normal breathing; they are a sign
of cardiac arrest.
9. When should a single rescuer activate the emergency response system for an adult victim?
A. Immediately after determining unresponsiveness
B. After checking for a pulse
C. After 2 minutes of CPR
D. After giving the first two rescue breaths
Correct Answer – A
Rationale – For a single rescuer with an adult victim, the emergency response system should be
activated immediately after determining the victim is unresponsive.
10. What is the correct chest compression-to-ventilation ratio for a single rescuer performing
CPR on an adult?
A. 15 compressions to 2 breaths
B. 30 compressions to 1 breath
C. 30 compressions to 2 breaths
D. 15 compressions to 1 breath
Correct Answer – C
