SECTION 1: ADULT BASIC LIFE SUPPORT – CORE CONCEPTS
& HIGH-QUALITY CPR
Question 1: A 68-year-old male collapses in the hospital hallway. You find him
unresponsive, not breathing normally, and with no palpable pulse. According to the
2025 AHA BLS algorithm, what is the correct sequence of actions?
A) Activate emergency response, check pulse, begin chest compressions, open airway,
deliver rescue breaths
B) Check responsiveness, activate emergency response, check breathing and pulse
simultaneously, begin chest compressions, use AED
C) Open airway, check breathing, deliver two rescue breaths, check pulse, begin chest
, 3
compressions
D) Check pulse, activate emergency response, deliver rescue breaths, begin chest
compressions, apply AED
- detailed answer 100% correct :- B
Rationale: The 2025 AHA BLS algorithm emphasizes a streamlined approach: check
responsiveness, activate the emergency response system (get AED/defibrillator),
simultaneously check breathing and pulse (no more than 10 seconds), begin high-
quality chest compressions if no pulse and no normal breathing, and use the AED as
soon as available. The CAB (Compressions-Airway-Breathing) sequence prioritizes
immediate chest compressions.
Question 2: Which of the following BEST defines high-quality chest compressions in an
adult according to 2025 AHA guidelines?
A) Rate of 80-100/min, depth of at least 2 inches, allowing partial chest recoil,
minimizing interruptions
B) Rate of 100-120/min, depth of 2-2.4 inches (5-6 cm), allowing full chest recoil,
minimizing interruptions to less than 10 seconds
C) Rate of 120-140/min, depth of 2.5-3 inches, allowing full chest recoil, no interruptions
D) Rate of 90-110/min, depth of 1.5-2 inches, allowing partial recoil, interruptions less
than 5 seconds
- detailed answer 100% correct :- B
Rationale: High-quality CPR requires a compression rate of 100-120 per minute, a
depth of 2-2.4 inches (5-6 cm) for adults, full chest recoil after each compression,
minimal interruptions (pauses less than 10 seconds), and a compression fraction of at
least 60%.
Question 3: What is the recommended compression-to-ventilation ratio for a single
rescuer performing CPR on an adult?
A) 15:2
B) 30:2
, 4
C) 30:1
D) 15:1
- detailed answer 100% correct :- B
Rationale: The recommended compression-to-ventilation ratio for single rescuers is
30:2 for all age groups, balancing oxygenation and perfusion.
Question 4: You are performing CPR on an adult with an advanced airway (endotracheal
tube) in place. What should be the ventilation rate?
A) 1 breath every 3 seconds (20 breaths/min)
B) 1 breath every 5 seconds (12 breaths/min)
C) 1 breath every 6 seconds (10 breaths/min)
D) 2 breaths every 30 compressions
- detailed answer 100% correct :- C
Rationale: When an advanced airway is in place during CPR, continuous chest
compressions should be given without pauses for ventilation. Rescue breaths should be
delivered at a rate of 1 breath every 6 seconds (10 breaths per minute).
Question 5: A healthcare provider is performing CPR on an adult. Which finding
indicates that chest compressions are being performed with adequate depth?
A) The sternum depresses approximately 1.5 inches
B) Visible chest rise with each compression
C) The sternum depresses approximately 2-2.4 inches (5-6 cm)
D) The rescuer's elbows remain locked throughout
- detailed answer 100% correct :- C
Rationale: Adequate compression depth for an adult is 2-2.4 inches (5-6 cm). Visible
chest rise relates to ventilation adequacy, not compression depth.
