Section 1: BLS & High-Performance CPR (Questions 1–8)
Q1: A healthcare provider arrives to find an unresponsive adult patient. After confirming no breathing
and no palpable carotid pulse within 10 seconds, what is the priority action?
A. Open the airway with a head-tilt chin-lift
B. Deliver two rescue breaths
C. Begin chest compressions
D. Attach the AED pads
Correct Answer: C
Rationale: Per the 2025 AHA guidelines, chest compressions should be started immediately after pulse
check in a cardiac arrest; early compressions maintain coronary and cerebral perfusion pressure.
[CORRECT]
Q2: During two-rescuer adult CPR, the compressor is performing chest compressions. How often should
the rescuer providing ventilations deliver breaths without an advanced airway in place?
A. Every 5 seconds (10–12 breaths/min)
B. Every 6 seconds (10 breaths/min)
C. Every 2 seconds (30 breaths/min)
D. Every 30 compressions
Correct Answer: B
Rationale: For two-rescuer adult CPR without an advanced airway, the compression-to-ventilation ratio
is 30:2, which approximates one breath every 6 seconds or 10 breaths per minute, allowing for adequate
oxygenation without overventilation. [CORRECT]
Q3: High-quality CPR requires chest compressions at what depth and rate for an adult?
,A. Depth 1–1.5 inches, rate 80–100/min
B. Depth 2–2.4 inches (5–6 cm), rate 100–120/min
C. Depth 3–4 inches, rate 120–140/min
D. Depth 1.5–2 inches, rate 90–110/min
Correct Answer: B
Rationale: AHA guidelines specify adult compression depth of at least 2 inches (5 cm) but not exceeding
2.4 inches (6 cm), at a rate of 100–120 compressions per minute; this optimizes cardiac output while
minimizing injury risk. [CORRECT]
Q4: During CPR, the compressor should allow the chest to:
A. Remain partially compressed
B. Recoil completely to allow venous return and cardiac filling
C. Be held down between compressions
D. Recoil only halfway
Correct Answer: B
Rationale: Full chest recoil between compressions allows the heart to refill with blood; incomplete recoil
reduces preload, coronary perfusion, and overall cardiac output during resuscitation. [CORRECT]
Q5: The compression fraction (percentage of time spent compressing) should ideally be:
A. >50%
B. >60%
C. >80%
D. >90%
Correct Answer: C
Rationale: AHA recommends maintaining a compression fraction >80%, meaning chest compressions
should be delivered more than 80% of the total resuscitation time; minimizing pauses for rhythm checks,
pulse checks, and intubation improves coronary and cerebral perfusion. [CORRECT]
Q6: A rescuer is performing one-rescuer CPR on an adult. The compression-to-ventilation ratio is:
A. 15:2
B. 30:2
C. 15:1
D. 5:1
, Correct Answer: B
Rationale: One-rescuer adult CPR uses a 30:2 compression-to-ventilation ratio; this prioritizes
compressions while providing adequate ventilation, and is consistent across adult BLS for lay rescuers
and healthcare providers. [CORRECT]
Q7: During CPR with an advanced airway (ETT or supraglottic airway) in place, ventilations should be
delivered:
A. Every 30 compressions (synchronized)
B. Every 6 seconds (10 breaths/min) asynchronously without pausing compressions
C. Every 2 seconds (30 breaths/min)
D. Only after ROSC
Correct Answer: B
Rationale: With an advanced airway, compressions continue uninterrupted at 100–120/min while
ventilations are delivered asynchronously every 6 seconds (10 breaths/min); this eliminates compression
pauses and maintains perfusion pressure. [CORRECT]
Q8: Switching compressors during CPR should occur:
A. Never
B. Every 2 minutes or 5 cycles to prevent fatigue and maintain compression quality
C. Only when the patient wakes up
D. Every 10 minutes
Correct Answer: B
Rationale: Compressor fatigue begins within 2 minutes, causing decreased depth and rate; rotating
compressors every 2 minutes (or 5 cycles) maintains high-quality compressions and is typically
coordinated with rhythm checks in two-rescuer scenarios. [CORRECT]
Section 2: Cardiac Arrest Algorithms (Questions 9–20)
Q9: A patient in the ICU suddenly becomes unresponsive and pulseless. The cardiac monitor shows
ventricular fibrillation. After starting CPR and defibrillating with 200J biphasic, the rhythm persists as VF.
What is the immediate next action according to the AHA Adult Cardiac Arrest Algorithm?
A. Administer epinephrine 1 mg IV
B. Resume CPR for 2 minutes
C. Administer amiodarone 300 mg IV push
D. Check for a pulse
