Introduction
This comprehensive examination is designed to assess the candidate's proficiency in
the critical principles and practices of Basic Life Support (BLS) as established by the
HeartCode program. The test rigorously evaluates both foundational theory and the
practical application of knowledge in high-stakes, real-world scenarios. Candidates
will demonstrate their understanding of the Chain of Survival, high-quality CPR
metrics, AED operation, and the differentiation of care for patients across all age
groups. Through a combination of multiple-choice and scenario-based questions,
this assessment emphasizes clinical decision-making, adherence to current
guidelines, and the professional standards required for effective emergency
response. Mastery of this content is essential for healthcare providers and first
responders to ensure optimal patient outcomes.

SECTION ONE: QUESTIONS 1 – 50
1. A 45-year-old man collapses suddenly. You are the first healthcare provider to
arrive. What is the correct sequence of actions for your initial approach?
A. Check for a pulse, check for breathing, then activate the emergency response
system.
B. Activate the emergency response system, check for breathing, then check for a
pulse.
C. Check for responsiveness, activate the emergency response system, then check
for breathing and a pulse simultaneously.
D. Check for breathing, provide two rescue breaths, then check for a pulse.
🟢 Correct Answer: C. Check for responsiveness, activate the emergency response
system, then check for breathing and a pulse simultaneously.
🔴 Explanation: The correct initial approach for a single rescuer is to first verify
unresponsiveness. After confirming the victim is unresponsive, the rescuer should
activate the emergency response system (or send someone to do so). The rescuer
should then simultaneously check for breathing and a pulse for no more than 10
seconds to minimize delays in starting CPR.
2. Which of the following is the most critical component of high-quality CPR
when providing chest compressions to an adult?
A. A compression rate of 80 to 100 per minute.
B. A compression depth of at least 2 inches (5 cm).
,C. Allowing the chest to fully recoil after each compression.
D. Performing compressions with your elbows locked.
🟢 Correct Answer: B. A compression depth of at least 2 inches (5 cm).
🔴 Explanation: While all components are important, adequate compression
depth is a key determinant of perfusion. The guidelines recommend a depth of at
least 2 inches (5 cm) but no more than 2.4 inches (6 cm) for an adult. Inadequate
depth significantly reduces the likelihood of successful defibrillation and survival.
3. You and a team of rescuers are performing CPR on a 6-year-old child. What is
the appropriate compression-to-ventilation ratio for a two-person team
performing CPR in a healthcare setting?
A. 15:2
B. 30:2
C. 15:1
D. 30:1
🟢 Correct Answer: A. 15:2
🔴 Explanation: For pediatric victims (from 1 year of age to puberty), the
compression-to-ventilation ratio for two healthcare providers performing CPR is
15:2. This is increased to 30:2 for a single rescuer. This ratio is optimized to
provide more ventilations relative to compressions for victims of cardiac arrest
caused by respiratory failure.
4. What is the primary purpose of a recovery position for an unresponsive,
breathing victim?
, A. To keep the airway open and allow fluids to drain from the mouth.
B. To facilitate the delivery of rescue breaths if needed.
C. To prevent the victim from moving and causing further injury.
D. To improve circulation to the heart and brain.
🟢 Correct Answer: A. To keep the airway open and allow fluids to drain from the
mouth.
🔴 Explanation: The recovery position is used for victims who are unresponsive
but are breathing normally and have a pulse. The primary purpose is to maintain
a patent airway and allow any vomit or fluids to drain from the mouth, thereby
preventing aspiration and airway obstruction.
5. An AED advises a "shock" for a patient in cardiac arrest. After the shock is
delivered, what is the immediate next step for the healthcare provider?
A. Check for a pulse to confirm the shock was successful.
B. Immediately resume chest compressions starting with CPR.
C. Analyze the rhythm again with the AED.
D. Provide two rescue breaths.
🟢 Correct Answer: B. Immediately resume chest compressions starting with CPR.
🔴 Explanation: After a shock is delivered, the AED will re-analyze the rhythm.
However, the immediate next step for the rescuer is to resume chest
compressions without delay. This minimizes interruptions in chest compressions,
which is critical for maintaining coronary perfusion pressure. The rhythm check
will occur after a 2-minute cycle of CPR.
