o A) 60–80 per minute
o B) 80–100 per minute
o C) 100–120 per minute
o D) 120–140 per minute
o Answer: C. 100–120 per minute

8. What is the compression-to-breath ratio for 2-rescuer infant CPR?
o A) 15:2
o B) 30:2
o C) 5:1
o D) 10:1
o Answer: A. 15:2
o Rationale: Two-rescuer infant CPR uses a 15:2 ratio for better coordination.
9. How should you open the airway if a neck injury is suspected?
o A) Head-tilt/chin-lift
o B) Jaw-thrust maneuver
o C) Chin-lift only
o D) Head-tilt only
o Answer: B. Jaw-thrust maneuver
o Rationale: The jaw-thrust avoids neck movement, protecting the spine.
10. What should you do if a victim has a pulse but is not breathing?
o A) Start chest compressions
o B) Give rescue breaths only
o C) Apply an AED
o D) Monitor and wait
o Answer: B. Give rescue breaths only
o Rationale: Rescue breaths support ventilation without compressions if a pulse is
present.
11. What is the ventilation rate for a child in respiratory arrest?
o A) 1 breath every 6 seconds
o B) 1 breath every 2–3 seconds
o C) 1 breath every 10 seconds
o D) 1 breath every 1 second
