Answers Verified Correct
This examination is designed to assess mastery of Basic Life Support (BLS) content aligned with the 2026/2027 American
Heart Association (AHA) BLS Provider Manual and current AHA Guidelines for Cardiopulmonary Resuscitation and
Emergency Cardiovascular Care. The test bank emphasizes the Chain of Survival (adult and pediatric, in-hospital and
out-of-hospital), high-quality CPR components (rate, depth, recoil, minimizing interruptions), adult and pediatric BLS
sequences, AED operation and special situations, airway management, team dynamics, choking relief, and special
resuscitation situations including opioid overdose, drowning, pregnancy, and hypothermia. Each question includes a
verified rationale that doubles as study-guide content, citing AHA Guidelines rationale and explaining why distractors
represent common BLS exam pitfalls. Cognitive level distribution: approximately 35% recall, 45% application, and 20%
analysis. Question style: 65% scenario-based, 35% direct recall of rates, depths, ratios, and sequences.
SECTION 1: BLS Program Overview and Chain of Survival
Adult, Pediatric, In-Hospital, & Out-of-Hospital | Questions 1-10 | 10 Questions
This section addresses the foundational BLS program structure and the Chain of Survival across adult and pediatric,
in-hospital and out-of-hospital settings.
Q1. The adult out-of-hospital Chain of Survival revised by the 2020 AHA Guidelines adds which link as the
FIRST step in the out-of-hospital chain?
A. Early high-quality CPR delivered by bystanders
B. Recognition of cardiac arrest and activation of the emergency response system [CORRECT]
C. Immediate defibrillation with an AED
D. Advanced life support by EMS personnel
Correct Answer: B — Recognition of cardiac arrest and activation of the emergency response system
Rationale: Per the 2020 AHA Guidelines update, the adult out-of-hospital Chain of Survival begins with
'Recognition of cardiac arrest and activation of the emergency response system.' Option B is correct because
activation must precede CPR, defibrillation, or advanced support. Option A is the second link. Option C is the
third link. Option D is the fourth link. The 2020 update explicitly separated recognition/activation from CPR as
distinct links to emphasize early 911 contact and dispatcher-assisted CPR.

Q2. Which of the following BEST describes a key difference between the in-hospital and out-of-hospital adult
Chains of Survival?
A. The in-hospital chain does not include defibrillation
B. The in-hospital chain includes 'surveillance and prevention' as the first link, recognizing that hospitalized
patients often have warning signs before arrest [CORRECT]
C. The in-hospital chain eliminates post-cardiac arrest care
D. The out-of-hospital chain includes advanced airway management as the first step
Correct Answer: B — The in-hospital chain includes 'surveillance and prevention' as the first link,
recognizing that hospitalized patients often have warning signs before arrest
Rationale: The 2020 AHA Guidelines identify 'surveillance and prevention' as the first link of the in-hospital
Chain of Survival because hospitalized patients often display physiological warning signs (e.g., vital sign
deterioration) before arrest. The out-of-hospital chain begins with recognition and activation instead. Options A,
C, and D are incorrect - both chains include defibrillation and post-cardiac arrest care; advanced airway
management is not a distinct Chain link.
Q3. The pediatric out-of-hospital Chain of Survival differs from the adult out-of-hospital chain most notably
in its emphasis on:
A. Immediate defibrillation as the priority intervention
B. Prevention of cardiac arrest and early, effective CPR, since most pediatric arrests are respiratory rather
than primary cardiac [CORRECT]
C. Advanced airway placement before any CPR
D. Use of mechanical CPR devices for children
Correct Answer: B — Prevention of cardiac arrest and early, effective CPR, since most pediatric arrests
are respiratory rather than primary cardiac
Rationale: Most pediatric cardiac arrests are precipitated by respiratory failure or shock rather than primary
arrhythmia, so the pediatric Chain of Survival emphasizes prevention and early, effective ventilation/CPR.
Option A is incorrect because defibrillation is less often indicated in children. Options C and D are incorrect -
pediatric arrest priorities are oxygenation and perfusion, not advanced airway first or mechanical devices.
Q4. How many links does the 2020 AHA adult in-hospital Chain of Survival contain, and what is its final link?
A. Five links; final link is rapid defibrillation
B. Six links; final link is recovery (post-cardiac arrest care, rehabilitation, and survivor support) [CORRECT]
C. Four links; final link is advanced resuscitation
D. Seven links; final link is transport to ICU
Correct Answer: B — Six links; final link is recovery (post-cardiac arrest care, rehabilitation, and
survivor support)
Rationale: The 2020 AHA update expanded both adult chains to include 'recovery' as the final link - covering
post-cardiac arrest care, rehabilitation, and long-term survivor support. The in-hospital chain has six links:
surveillance and prevention, recognition and activation, immediate high-quality CPR, rapid defibrillation,
advanced resuscitation, and recovery. Options A, C, and D misstate either the link count or the final link.

Q5. In the out-of-hospital setting, a bystander witnesses sudden collapse. According to the Chain of Survival,
what should the bystander do FIRST?
A. Begin chest compressions immediately, then call 911 after 2 minutes of CPR
B. Recognize the arrest (no response, no breathing), call 911 (or have someone call), and dispatch the
emergency response system; obtain an AED if available [CORRECT]
C. Wait to confirm pulselessness for a full minute before acting
D. Administer rescue breaths before any other intervention
Correct Answer: B — Recognize the arrest (no response, no breathing), call 911 (or have someone call),
and dispatch the emergency response system; obtain an AED if available
Rationale: The first link of the out-of-hospital chain is recognition of cardiac arrest (unresponsiveness and
absent or agonal breathing) and activation of the emergency response system. The 2020 AHA Guidelines stress
early 911 activation with dispatcher-assisted CPR. Option A delays activation. Option C wastes valuable time.
Option D prioritizes ventilation over circulation, contrary to current adult BLS priorities.
Q6. Which component is NOT one of the original 1991 Chain of Survival links but is now part of the modern
AHA Chain of Survival?
A. Early access (recognition and activation)
B. Early CPR
C. Early advanced care
D. Recovery (post-arrest care and rehabilitation) [CORRECT]
Correct Answer: D — Recovery (post-arrest care and rehabilitation)
Rationale: 'Recovery' was added in the 2020 AHA Guidelines update as a new Chain of Survival link,
recognizing that survival extends beyond ROSC to include rehabilitation, neurological support, and long-term
survivorship. Options A, B, and C are part of both the original 1991 Chain and the current Chain of Survival.
Q7. In a hospital medical-surgical unit, a nurse notes that a post-op patient's respiratory rate has steadily
declined over the past hour. Which Chain of Survival link is the nurse exercising by escalating this concern to
a rapid response team?
A. Surveillance and prevention [CORRECT]
B. Immediate high-quality CPR
C. Rapid defibrillation
D. Advanced resuscitation
Correct Answer: A — Surveillance and prevention
Rationale: The first link of the in-hospital Chain of Survival is 'surveillance and prevention' - monitoring
patients for deterioration and intervening before arrest occurs. Options B, C, and D represent later links activated
only after cardiac arrest has occurred. Early warning systems like rapid response teams are designed to
operationalize this first link.

Q8. Which of the following is the BEST description of integrated post-cardiac arrest care, the recovery link?
A. Cessation of CPR once ROSC is achieved and discharge from the hospital
B. Targeted temperature management (TTM), hemodynamic optimization, seizure control, percutaneous
coronary intervention when indicated, and rehabilitation including neurologic and psychological support
[CORRECT]
C. Immediate withdrawal of life-sustaining therapy if the patient does not wake within 6 hours
D. Transport to a skilled nursing facility within 24 hours
Correct Answer: B — Targeted temperature management (TTM), hemodynamic optimization, seizure
control, percutaneous coronary intervention when indicated, and rehabilitation including neurologic
and psychological support
Rationale: Integrated post-cardiac arrest care includes targeted temperature management, hemodynamic
optimization, seizure control, PCI if indicated, prognostication, and rehabilitation. Option A incorrectly truncates
care at ROSC. Option C is premature; prognostication should follow current guidelines. Option D is not a BLS
concept.
Q9. Which of the following BEST describes the role of telecommunicator/dispatcher CPR (T-CPR) within the
Chain of Survival?
A. It is optional and used only when callers are unwilling to perform CPR
B. It is an essential component of the recognition/activation and early CPR links, with dispatchers trained to
identify arrest, provide compression-only coaching, and reassure callers while help is en route [CORRECT]
C. It replaces the need for bystander CPR entirely
D. It is used only for pediatric arrests
Correct Answer: B — It is an essential component of the recognition/activation and early CPR links,
with dispatchers trained to identify arrest, provide compression-only coaching, and reassure callers
while help is en route
Rationale: T-CPR is an essential element of the early recognition and early CPR links of the Chain of Survival.
Dispatchers are trained to identify cardiac arrest from breathing questions, guide callers through
compression-only CPR, and reassure them until EMS arrives. Options A, C, and D mischaracterize T-CPR,
which is recommended for adult arrest callers of all skill levels.
