ACLS POST TEST ACTUAL EXAMS 3 VERSIONS (A, B & C) WITH ALL
400 QUESTIONS AND CORRECT VERIFIED ANSWERS ALREADY
GRADED A+ WITH RATIONALE
This comprehensive ACLS post-test bank contains 400 high-standard, multiple-
choice questions that mirror the rigor and format of the actual American Heart
Association certification exams. Each question is meticulously crafted with one
correct answer and three plausible distractors, accompanied by a detailed,
evidence-based rationale to reinforce learning and clinical reasoning. The content
spans the entire ACLS curriculum, including BLS fundamentals, high-quality
CPR, airway management, rhythm recognition, pharmacology, and the core
algorithms for cardiac arrest, bradycardia, tachycardia, ACS, and stroke.
Specialized sections cover pediatric advanced life support (PALS) modifications,
post-cardiac arrest care, toxicology, and the identification and treatment of
reversible causes (Hs and Ts). This resource is designed for healthcare providers
seeking to test their knowledge, identify knowledge gaps, and achieve mastery of
the critical concepts necessary for managing cardiovascular emergencies and
improving patient outcomes.
1 What is the compression to breath ratio in two-person CPR for an adult?
A) 20:2
B) 30:2
C) 40:2
D) 25:2
Correct Answer: B) 30:2
Rationale: The correct compression-to-ventilation ratio for adult CPR, whether
performed by one or two rescuers, is 30:2. This ratio is designed to maximize the
number of chest compressions delivered per minute while still providing adequate
ventilation. It is a critical component of high-quality CPR, as interruptions for
ventilations should be minimized to maintain coronary and cerebral perfusion
,pressure. When an advanced airway is in place, compressions are continuous at a
rate of 100-120 per minute and ventilations are delivered at a rate of one breath
every 6 seconds (10 breaths per minute), eliminating the 30:2 ratio.
2 Where should you palpate for a pulse on an unconscious adult during CPR?
A) Carotid pulse
B) Radial pulse
C) Femoral pulse
D) Brachial pulse
Correct Answer: A) Carotid pulse
Rationale: In an unconscious adult, the carotid artery is the preferred site for pulse
palpation during CPR. The carotid artery is centrally located and is easily
accessible in the neck, lying medial to the sternocleidomastoid muscle. Palpating
the carotid pulse allows the rescuer to assess for the presence of a central pulse,
which is a more reliable indicator of cardiac output than peripheral pulses like the
radial or femoral. The pulse check should be performed for at least 5 seconds but
no more than 10 seconds to minimize interruptions in chest compressions.
3 How long should you check for a carotid pulse on an adult?
A) For at least 30 seconds
B) For at least a full minute
C) 10-15 seconds
D) 5-10 seconds
Correct Answer: D) 5-10 seconds
Rationale: The AHA guidelines recommend that a pulse check be performed for at
least 5 seconds but no more than 10 seconds. This time frame allows the rescuer to
adequately assess for the presence of a pulse without causing significant
interruptions in chest compressions. Prolonged pulse checks delay the delivery of
CPR, which is critical for patient survival. If a pulse is not definitively felt within
10 seconds, compressions should be resumed immediately.
4 Which of the following is NOT an element of effective resuscitation team
dynamics?
,A) Closed-loop communication
B) Clear roles and responsibilities
C) Multiple leaders of the team
D) Knowing one's limitations
Correct Answer: C) Multiple leaders of the team
Rationale: Effective resuscitation team dynamics rely on a single, clear leader who
directs the team's efforts and coordinates tasks. Having multiple leaders can lead to
confusion, conflicting instructions, and delays in care. The other options are
essential elements of a high-functioning team. Closed-loop communication ensures
that orders are acknowledged and completed, clear roles and responsibilities
prevent task duplication or omission, and knowing one's limitations ensures team
members ask for help when needed to maintain patient safety.
5 Basic airway skills include all of the following EXCEPT:
A) Head tilt-chin-lift maneuver
B) Jaw-thrust maneuver without head extension
C) Bag-mask ventilation
D) Placement of laryngeal mask airway (LMA)
Correct Answer: D) Placement of laryngeal mask airway (LMA)
Rationale: The placement of a laryngeal mask airway (LMA) is considered an
advanced airway skill, not a basic one. Basic airway skills are those that can be
performed with minimal equipment and training, including opening the airway
with a head tilt-chin lift or jaw-thrust maneuver, and providing basic ventilation
with a bag-mask device. Advanced airway placement, including LMA insertion,
endotracheal intubation, and placement of an esophageal-tracheal tube, requires
specialized training and is typically performed by more experienced providers.
6 What is the best way to relieve severe choking in a responsive adult?
A) Start CPR immediately
B) Perform abdominal thrusts
C) Give 5 back slaps followed by 2 breaths
D) Give 2 breaths, repositioning the airway after each breath
Correct Answer: B) Perform abdominal thrusts
, Rationale: In a responsive adult with severe airway obstruction, abdominal thrusts
(the Heimlich maneuver) are the recommended treatment. The rescuer stands
behind the patient, wraps their arms around the waist, and delivers inward and
upward thrusts to the upper abdomen. This increases intra-abdominal pressure,
forcing air from the lungs to expel the foreign body. If the patient becomes
unresponsive, CPR should be initiated immediately, starting with chest
compressions, as these can also generate enough force to dislodge an obstruction.
7 ACLS providers must make every effort to minimize any interruptions in chest
compressions to no longer than:
A) 10 seconds
B) 20 seconds
C) 30 seconds
D) 60 seconds
Correct Answer: A) 10 seconds
Rationale: Interruptions in chest compressions should be limited to no more than
10 seconds. This includes time taken for pulse checks, rhythm analysis, and
defibrillator charging. Minimizing interruptions is crucial because any pause in
compressions reduces coronary perfusion pressure, decreasing the likelihood of
return of spontaneous circulation (ROSC). High-quality CPR aims to achieve a
chest compression fraction of at least 60%, meaning compressions are delivered
for 60% or more of the total resuscitation time.
8 Which of the following are signs of airway obstruction?
A) Poor air exchange
B) High pitch noise while inhaling
C) Inability to speak
D) All of the above
Correct Answer: D) All of the above
Rationale: Signs of airway obstruction include poor air exchange or absent breath
sounds, high-pitched noises on inspiration (stridor), and the inability to speak or
cough effectively. Other signs include the universal choking sign (hands clutching
the throat), cyanosis, and altered mental status due to hypoxia. Partial obstructions
