Final Test Review (Qns & Ans)
2025
1. Adult Compression Quality
While performing high-quality CPR on an adult, which of the
following elements is most critical for maintaining coronary
perfusion?
A. Rapid rescue breaths
B. Adequate compression depth
C. Minimizing interruptions in chest compressions
D. Strict adherence to a 30:2 compression-to-ventilation ratio

, ANS: C
Rationale: Continuous chest compressions with minimal
interruptions are key to maintaining coronary and cerebral
perfusion pressure during CPR, directly impacting patient
outcomes.
2. Adult Compression Rate
What is the recommended chest compression rate for high-quality
adult CPR?
A. 80–100 compressions per minute
B. 90–110 compressions per minute
C. 100–120 compressions per minute
D. 120–140 compressions per minute
ANS: C
Rationale: The American Heart Association (AHA) guidelines
specify that a rate of 100–120 compressions per minute provides
optimal perfusion during adult CPR.
3. Adult Compression Depth
For adult CPR, what compression depth is recommended?
©2025
,A. At least 1 inch (2.5 cm)
B. Approximately 1.5 inches (4 cm)
C. At least 2 inches (5 cm) but not more than 2.4 inches (6 cm)
D. 3 inches (7.5 cm)
ANS: C
Rationale: Achieving a compression depth of at least 2 inches
(5 cm) while avoiding excessive depth (more than 2.4 inches)
ensures effective blood flow without increasing the risk of injury.
4. Pediatric Compression Depth
In pediatric CPR (children from age 1 up to puberty) by a rescuer,
what is the recommended compression depth?
A. One-half the chest’s anterior-posterior diameter
B. Approximately one-third of the chest’s anterior-posterior
diameter
C. At least 2 inches
D. Exactly 1 inch
ANS: B
©2025
, Rationale: For children, compressions should be delivered to a
depth equaling about one-third of the anterior–posterior diameter
of the chest to ensure effective circulation without causing injury.
5. Infant Compression Technique (Single Rescuer)
When performing CPR on an infant as a single rescuer, which
compression technique is recommended?
A. Two-thumb encircling technique
B. Two-finger technique
C. One-hand compression
D. Two-hand compression
ANS: B
Rationale: For a single rescuer, the two-finger technique is
recommended for infants because it provides more controlled and
effective compressions on a small chest.
6. Pediatric Compression Rate
What is the recommended chest compression rate for children
during CPR?
A. 60–80 compressions per minute
B. 100–120 compressions per minute
