, Q1
A single rescuer is performing CPR on an adult in cardiac arrest. What is the
recommended compression rate?
A) 60–80 per minute
B) 80–100 per minute
C) *100–120 per minute CORRECT
D) 120–140 per minute
Rationale
AHA recommends 100–120 compressions per minute for all age groups to optimize cardiac
output.
Q2
What is the recommended compression depth for an average adult during CPR?
A) *At least 2 inches (5 cm), not exceeding 2.4 inches (6 cm) CORRECT
B) At least 1 inch (2.5 cm)
C) At least 3 inches (7.6 cm)
D) Depth does not affect outcomes
Rationale
Adequate depth generates perfusion; excessive depth increases injury risk without added
benefit.
Q3
What is the correct compression-to-ventilation ratio for a single rescuer performing adult
CPR?
A) 15:1
B) 15:2
C) 10:2
