Section 1: High-Quality CPR and BLS Foundations
Q1: A 55-year-old man collapses in a public area. You and another bystander begin CPR.
What is the recommended compression rate for high-quality CPR in adults?
A. 80 to 100 compressions per minute
B. 100 to 120 compressions per minute [CORRECT]
C. 120 to 140 compressions per minute
D. At least 150 compressions per minute
Correct Answer: B
Rationale: The best answer is 100 to 120 compressions per minute. This aligns with current
AHA guidelines, ensuring adequate blood flow while allowing sufficient time for chest recoil
and venous return.
Q2: You are performing chest compressions on an adult patient in cardiac arrest. To ensure
high-quality CPR, what is the minimum recommended depth of compression?
A. At least 1 inch (2.5 cm)
B. At least 1.5 inches (3.8 cm)
C. At least 2 inches (5 cm) [CORRECT]
D. At least 2.5 inches (6.3 cm)
Correct Answer: C
Rationale: This choice is correct because compressions must be at least 2 inches (5 cm) deep
in adults to effectively pump blood from the heart, while avoiding excessive depth greater
than 2.4 inches to prevent injury.
Q3: During a resuscitation attempt, the team leader notices that chest compressions are
being interrupted for 25 seconds to check the rhythm and deliver a shock. What is the most
appropriate feedback to give the team?
A. Continue as planned, as rhythm checks require adequate time.
B. Limit all pulse and rhythm checks to less than 10 seconds. [CORRECT]
C. Increase the compression rate to make up for the lost time.
D. Skip the rhythm check and administer epinephrine immediately.
Correct Answer: B
Rationale: The best answer is to limit interruptions to less than 10 seconds. This matches the
principle that minimizing pauses in chest compressions is critical for maintaining coronary
perfusion pressure and improving survival outcomes.
, Q4: Which of the following best describes the goal of chest compression fraction (CCF)
during a cardiac arrest?
A. To ensure compressions are delivered at a rate of exactly 100 per minute.
B. To maximize the proportion of time chest compressions are performed over a given
minute. [CORRECT]
C. To guarantee that ventilations are delivered exactly every 6 seconds.
D. To measure the depth of each individual compression.
Correct Answer: B
Rationale: This choice is correct because chest compression fraction should be as high as
possible, ideally greater than 60%, meaning compressions are being performed for the
majority of the cardiac arrest event.
Q5: Why is allowing full chest recoil between compressions a critical component of high-
quality CPR?
A. It prevents the rescuer from becoming fatigued too quickly.
B. It allows the heart to refill with blood, maximizing cardiac output. [CORRECT]
C. It reduces the risk of rib fractures in the patient.
D. It ensures the automated external defibrillator can analyze the rhythm accurately.
Correct Answer: B
Rationale: This aligns with the physiological principle that incomplete recoil increases
intrathoracic pressure, which impedes venous return to the heart and drastically reduces
the effectiveness of the next compression.
Q6: You are the team leader during a code. Two rescuers are performing CPR. How often
should the compressor switch roles to prevent fatigue and maintain compression quality?
A. Every 1 minute
B. Every 2 minutes or sooner if fatigued [CORRECT]
C. Every 3 minutes
D. Only when the compressor explicitly asks for a break
Correct Answer: B
Rationale: The best answer is every 2 minutes or sooner if fatigued. This matches the AHA
recommendation to switch compressors during rhythm checks to prevent degradation in
compression depth and rate due to rescuer fatigue.
Q7: A patient is in cardiac arrest, and an advanced airway has just been placed. What is the
correct ventilation rate for this patient while continuous chest compressions are ongoing?
A. 1 breath every 3 to 5 seconds (12 to 20 breaths per minute)
B. 1 breath every 6 seconds (10 breaths per minute) [CORRECT]
C. 1 breath every 10 seconds (6 breaths per minute)
D. 2 breaths after every 30 compressions
Correct Answer: B
Rationale: This choice is correct because once an advanced airway is in place, providers
should deliver 1 breath every 6 seconds continuously, without pausing compressions for
ventilations.
Q8: During BLS assessment, you find an unresponsive adult patient who is not breathing
normally. What is your immediate next action?
