VERSION C
SECTION 1: HIGH-QUALITY BLS & CPR FUNDAMENTALS
1. What is the recommended compression-to-ventilation ratio for a
single rescuer in adult cardiac arrest?
A) 15:2
B) 30:2
C) Continuous compressions with asynchronous breaths at 10/min
D) 30:2 with 3-second pauses for breaths
CORRECT ANSWER: B) 30:2
Rationale: The 2020 AHA guidelines recommend a 30:2
compression-to-ventilation ratio for single-rescuer adult CPR to
maximize coronary perfusion pressure while providing adequate
ventilation.
,2. What is the minimum chest compression depth for an adult?
A) 1.5 inches (4 cm)
B) 2 inches (5 cm)
C) 2.4 inches (6 cm)
D) 2.5 inches (6.4 cm)
CORRECT ANSWER: C) 2.4 inches (6 cm)
Rationale: Current guidelines specify a target depth of 2-2.4 inches
(5-6 cm) for adult chest compressions, with a minimum of 2 inches (5
cm). The ideal is at least 2.4 inches for adequate cardiac output.
3. What is the maximum acceptable pause between stopping
compressions and delivering a shock?
A) 5 seconds
B) 8 seconds
C) 10 seconds
D) 15 seconds
CORRECT ANSWER: A) 5 seconds
,Rationale: To maximize the chance of successful defibrillation, the
peri-shock pause should be less than 5 seconds. Prolonged pauses
reduce the likelihood of return of spontaneous circulation (ROSC).
4. After delivering a shock during cardiac arrest, when should
compressions resume?
A) Immediately after shock delivery, without rhythm check
B) After a 10-second rhythm check
C) After checking for a pulse
D) After delivering a second shock
CORRECT ANSWER: A) Immediately after shock delivery,
without rhythm check
Rationale: Compressions should resume immediately after
defibrillation. Rhythm checks should occur only after 2 minutes of
CPR, unless the patient shows signs of ROSC.
5. Which device provides the most reliable indicator of CPR quality
during cardiac arrest?
A) Pulse oximeter
B) End-tidal CO2 (EtCO2) capnography
C) Non-invasive blood pressure cuff
, D) Finger-probe Doppler
CORRECT ANSWER: B) End-tidal CO2 (EtCO2) capnography
Rationale: EtCO2 values correlate with cardiac output during CPR.
Values below 10 mmHg suggest poor compressions, while a sudden
increase to >40 mmHg may indicate ROSC.
6. What compression fraction should be targeted during ACLS
resuscitation?
A) >60%
B) >70%
C) >80%
D) >90%
CORRECT ANSWER: C) >80%
Rationale: High-quality CPR requires a compression fraction of at
least 80%, meaning chest compressions are performed for at least
80% of the resuscitation time. Minimizing interruptions maximizes
coronary and cerebral perfusion.
7. What is the recommended chest compression rate per minute for
adults?
