, SECTION 1: BLS AND CPR QUALITY (Questions 1-25)
This section covers high-quality CPR, compression characteristics, ventilations, and the BLS
Survey.
1. What is the recommended compression rate for high-quality CPR in adults?
A. 60-80 compressions per minute
B. 80-100 compressions per minute
C. 100-120 compressions per minute
D. 120-140 compressions per minute
Correct Answer: C. 100-120 compressions per minute
Rationale: High-quality CPR requires a compression rate of 100-120 per minute. This rate
optimizes coronary perfusion pressure and cardiac output. Compressions that are too slow or
too fast reduce the effectiveness of CPR.
2. What is the recommended compression depth for adult CPR?
A. At least 1 inch (2.5 cm)
B. At least 2 inches (5 cm)
C. At least 2.4 inches (6 cm)
D. At least 3 inches (7.5 cm)
Correct Answer: B. At least 2 inches (5 cm)
Rationale: The AHA recommends a compression depth of at least 2 inches (5 cm) but no more
than 2.4 inches (6 cm) for adult CPR. Adequate depth ensures sufficient blood flow to vital
organs.
3. What is the recommended compression-to-ventilation ratio for a single rescuer performing
CPR on an adult?
A. 15:2
B. 30:2
2
, C. 30:1
D. 15:1
Correct Answer: B. 30:2
Rationale: The compression-to-ventilation ratio for a single rescuer performing CPR on an adult
is 30:2. This ratio maximizes the number of compressions while providing adequate ventilation.
4. A patient is in cardiac arrest. After 2 minutes of CPR, the rhythm check reveals a shockable
rhythm. What is the maximum interval between the last compression and the delivery of the
shock?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
Correct Answer: A. 5 seconds
Rationale: The interval between the last compression and shock delivery should be less than 5
seconds. Minimizing this interval increases the likelihood of successful defibrillation.
5. Which of the following is a component of high-quality CPR?
A. Allowing full chest recoil between compressions
B. Compressing at a rate of 80-100 compressions per minute
C. Interrupting compressions for more than 10 seconds for rhythm checks
D. Providing excessive ventilation
Correct Answer: A. Allowing full chest recoil between compressions
Rationale: Allowing full chest recoil between compressions is essential for adequate venous
return and coronary perfusion. Interruptions should be minimized, ventilation should not be
excessive, and the compression rate should be 100-120 per minute.
6. In a patient with an advanced airway in place during cardiac arrest, how often should
ventilations be delivered?
A. Every 3-5 seconds (12-20 breaths per minute)
B. Every 6 seconds (10 breaths per minute)
3
, C. Every 10 seconds (6 breaths per minute)
D. Every 15 seconds (4 breaths per minute)
Correct Answer: B. Every 6 seconds (10 breaths per minute)
Rationale: When an advanced airway (endotracheal tube or supraglottic airway) is in place
during cardiac arrest, deliver one breath every 6 seconds (10 breaths per minute) without
interrupting chest compressions.
7. What is the recommended compression-to-ventilation ratio for a two-rescuer CPR on a
child?
A. 15:2
B. 30:2
C. 15:1
D. 30:1
Correct Answer: A. 15:2
Rationale: For pediatric CPR (child or infant), the compression-to-ventilation ratio for two
rescuers is 15:2. For single rescuer, the ratio is 30:2. This provides more ventilations relative to
compressions for children.
8. A patient in cardiac arrest has a palpable pulse but is not breathing adequately. What is the
appropriate ventilation rate?
A. 1 breath every 3-5 seconds (12-20 breaths per minute)
B. 1 breath every 6 seconds (10 breaths per minute)
C. 1 breath every 10 seconds (6 breaths per minute)
D. 1 breath every 15 seconds (4 breaths per minute)
Correct Answer: A. 1 breath every 3-5 seconds (12-20 breaths per minute)
Rationale: For a patient with a pulse but inadequate breathing, provide rescue breathing at a
rate of 1 breath every 3-5 seconds (12-20 breaths per minute). Reassess the pulse every 2
minutes.
9. Which of the following is the most important factor in improving survival from cardiac
arrest?
