Overview:
This Basic Life Support (BLS) practice examination is a comprehensive, AHA-aligned
assessment designed to evaluate knowledge and clinical decision-making related to high-quality
CPR, AED use, airway management, rescue breathing, choking response, and team-based
resuscitation. The exam consists of 100 most-tested, scenario-based multiple-choice questions,
each including the correct answer in bold with a clear rationale. It emphasizes adult, child, and
infant life support, special populations, and emergency response principles to prepare learners
for successful BLS certification and real-world emergency care
1.
What is the first action when you find an unresponsive adult?
A. Start chest compressions
B. Check pulse
C. Ensure scene safety and check responsiveness
D. Get the AED
Rationale: Scene safety and responsiveness must be assessed before initiating
care.
2.
What is the correct compression rate for adult CPR?
A. 80–100/min
B. 90–110/min
,C. 100–120/min
D. 120–140/min
Rationale: AHA recommends compressions at 100–120 per minute for
effective perfusion.
3.
What is the correct compression depth for an adult?
A. 1 inch
B. 1.5 inches
C. At least 2 inches (5 cm)
D. 3 inches
Rationale: Adequate depth ensures sufficient blood flow to vital organs.
4.
What is the correct compression-to-ventilation ratio for a single rescuer adult
CPR?
A. 15:2
B. 30:2
C. 20:2
D. 30:1
Rationale: AHA recommends 30 compressions to 2 breaths for adults.
5.
When should the AED be used?
,A. After 5 minutes of CPR
B. Only when EMS arrives
C. As soon as it is available
D. After checking pulse for 30 seconds
Rationale: Early defibrillation greatly increases survival.
6.
What is the correct hand placement for adult chest compressions?
A. Over the ribs
B. Lower half of sternum
C. Center of chest on the lower half of the sternum
D. Upper chest
Rationale: Proper placement maximizes compression effectiveness and
reduces injury.
7.
What should you do if the AED advises “no shock”?
A. Stop CPR
B. Recheck pulse only
C. Resume CPR immediately
D. Remove AED pads
Rationale: CPR should resume immediately when no shock is advised.
8.
, What is the correct action if a victim starts breathing normally?
A. Continue CPR
B. Apply AED
C. Place in recovery position and monitor
D. Give rescue breaths
Rationale: Normal breathing indicates ROSC; continue monitoring.
9.
What is the compression depth for a child?
A. 1 inch
B. About 2 inches (5 cm)
C. Same as adult
D. 3 inches
Rationale: Child compressions should be about 2 inches or 1/3 chest depth.
10.
What is the compression depth for an infant?
A. 1 inch
B. About 1.5 inches (4 cm)
C. 2 inches
D. 3 inches
Rationale: Infant CPR depth is 1.5 inches or 1/3 chest depth.
