BLS FINAL EXAM – 2026 ACTUAL
EXAM QUESTIONS| BASED ON LATEST
AHA GUIDELINES
SECTION 1: HIGHQUALITY CPR (Questions 150)
1. What is the correct compressiontoventilation ratio for a single rescuer
performing CPR on an adult?
A) 30:1
B) 30:2
C) 15:1
D) 15:2
Correct Answer: B) 30:2
Rationale: The 2025 AHA Guidelines recommend a ratio of 30 compressions
to 2 ventilations for single rescuer CPR on adults, children, and infants
(excluding newborns).
2. How often should rescuers switch roles during two rescuer CPR to prevent
fatigue?
,A) After every cycle of CPR
B) After every two cycles of CPR
C) After every five cycles of CPR (approximately 2 minutes)
D) After every 10 cycles of CPR
Correct Answer: C) After every five cycles of CPR (approximately 2 minutes)
Rationale: Rescuers should switch roles approximately every 2 minutes, or
after 5 cycles of 30:2. This prevents fatigue, which can lead to inadequate
compression depth and rate.
3. What is the recommended rate for chest compressions for all age groups
(excluding newborns)?
A) 80100 per minute
B) 100120 per minute
C) 120140 per minute
D) 140160 per minute
Correct Answer: B) 100120 per minute
Rationale: The 2025 Guidelines recommend a compression rate of 100–120
per minute to maintain adequate coronary and cerebral perfusion during CPR.
,4. What is the correct rate of chest compressions for adults during CPR?
A) 60–80 per minute
B) 80–100 per minute
C) 100–120 per minute
D) 120–140 per minute
Correct Answer: C) 100–120 per minute
Rationale: The AHA recommends a compression rate of 100–120 per minute
to maintain adequate coronary and cerebral perfusion during CPR.
5. How deep should adult chest compressions be?
A) At least 1 inch (2 cm)
B) About 1.5 inches (4 cm)
C) At least 2 inches (5 cm)
D) More than 3 inches
Correct Answer: C) At least 2 inches (5 cm)
Rationale: Adequate depth ensures sufficient blood circulation during CPR.
The minimum depth for adult chest compressions is at least 2 inches (5 cm).
, 6. What is the minimum depth of chest compression for an average adult?
A) 2 cm
B) 4 cm
C) 5 cm
D) 6 cm
Correct Answer: C) 5 cm
Rationale: According to the AHA, the minimum depth of chest compression
should be at least 2 inches (5 cm) for an average adult.
7. Why is complete chest recoil essential between each compression?
A) To give rest to the rescuer
B) To prevent injury to the patient
C) To allow the heart to fill with blood
D) To allow blood delivery to the brain
Correct Answer: C) To allow the heart to fill with blood
Rationale: Complete chest recoil ensures that the patient's heart is fully
refilled with blood, allowing maximum stroke volume during the next
compression.
