CPR?
A. 15:2
B. 30:2
C. 5:1
D. 50:2
Rationale: 30 compressions followed by 2 breaths is recommended for adult single-rescuer CPR.
Q2. How deep should chest compressions be for an adult?
A. 1 inch
B. 1.5 inches
C. 2–2.4 inches (5–6 cm)
D. 3 inches
Rationale: Depth of 2–2.4 inches is needed for effective perfusion.
Q3. The correct hand placement for adult chest compressions is:
A. Lower abdomen
B. Upper chest
C. Center of the chest on the lower half of the sternum
D. Left side of the chest
Rationale: Proper hand placement ensures compressions are effective and reduces injury risk.

, D. Only if tired
Rationale: Switching every 2 minutes maintains effective compressions.
Q5. The rate of chest compressions during CPR should be:
A. 60–80 per minute
B. 100–120 per minute
C. 140–160 per minute
D. 80–100 per minute
Rationale: 100–120 compressions per minute optimizes blood flow.
Q6. The first step in BLS for an adult is:
A. Start compressions immediately
B. Give two rescue breaths
C. Check responsiveness and call for help
D. Apply an AED
Rationale: Assessing responsiveness ensures the patient needs CPR and activates EMS early.
Q7. For a child (1–8 years old) with two rescuers, the compression-to-ventilation ratio is:
A. 30:2
B. 15:2
C. 5:1
D. 50:2
Rationale: Pediatric CPR with two rescuers uses 15 compressions to 2 breaths.
Q8. When using an AED, the first action after turning it on is:
A. Deliver a shock immediately
B. Follow the voice prompts
C. Start compressions
D. Check pulse
Rationale: AEDs guide the rescuer step-by-step; following prompts ensures safe and correct use.
Q9. During CPR, if the patient starts breathing normally but remains unresponsive, you should:
A. Continue CPR
B. Place in recovery position and monitor
C. Give 5 rescue breaths
D. Stop and leave the patient
Rationale: Recovery position maintains airway while monitoring until help arrives.
Q10. In a choking adult who becomes unresponsive, the next step is:
A. Give abdominal thrusts
B. Encourage coughing
C. Begin CPR starting with compressions
D. Wait for emergency services
Rationale: CPR should be started to relieve obstruction and maintain circulation.
