2026-2027 UPDATE EXAM PREPARATION
Subject: Advanced Cardiovascular Life Support (ACLS)
Update Cycle: 2026-2027 Guidelines
Resource Grounding: Derived from standard exam benchmarks for comprehensive preparation.
Format: 50 Multiple Choice Questions with detailed answers and professional rationale.
PREPARATION DIRECTIONS: This study material serves as a professional, grounded preparation resource
for the Advanced Cardiovascular Life Support (ACLS) Written Exam. It features 50 comprehensive
multiple-choice questions matching the rigor and distribution of the official benchmark. Review each
question, select your choice, and utilize the detailed explanations to master the clinical concepts,
procedures, and terminology.
PRACTICE QUESTIONS & ANSWER EXPLANATIONS
Question 1:
You find an unresponsive patient who is not breathing. After activating the emergency response
system, you determine that there is no pulse. What is your next action?
A. Open the airway with a head tilt–chin lift.
B. Administer epinephrine at a dose of 1 mg/kg.
C. Deliver 2 rescue breaths each over 1 second.
D. Start chest compressions at a rate of at least 100/min.
ANSWER : D — Start chest compressions at a rate of at least 100/min.
Explanation: According to the adult cardiac arrest guidelines, once cardiac arrest is recognized (unresponsive,
no normal breathing, no pulse), you must immediately begin chest compressions (C-A-B sequence). Minimizing
the delay to compressions is critical for sustaining coronary and cerebral perfusion. Rescue breathing and airway
maneuvers are addressed after starting the first cycle of chest compressions. Epinephrine is administered later at
a dose of 1 mg IV/IO every 3-5 minutes, not 1 mg/kg (which would be a massive overdose).

Question 2:
You are evaluating a 58-year-old man with chest pain. The blood pressure is 92/50 mm Hg, the
heart rate is 92/min, the nonlabored respiratory rate is 14 breaths/min, and the pulse oximetry
reading is 97%. What assessment step is most important now?
A. PETCO2
B. Chest x-ray
C. Laboratory testing
D. Obtaining a 12-lead ECG
ANSWER : D — Obtaining a 12-lead ECG
Explanation: For any patient presenting with suspected acute coronary syndrome (ACS) or ischemic chest pain,
obtaining a 12-lead ECG within 10 minutes of arrival is the single most critical assessment step. This allows for
rapid identification of ST-segment elevation myocardial infarction (STEMI) or other ischemic signs, guiding
immediate reperfusion therapy. Other tests like a chest x-ray or blood work are secondary and should not delay
the ECG.
Question 3:
What is the preferred method of access for epinephrine administration during cardiac arrest in
most patients?
A. Intraosseous
B. Endotracheal
C. Central intravenous
D. Peripheral intravenous
ANSWER : D — Peripheral intravenous
Explanation: Peripheral intravenous (IV) access is the preferred route for drug administration during resuscitation
because it is simpler and quicker to establish than central venous access and does not require interrupting CPR.
If IV access cannot be established, intraosseous (IO) access is the next preferred route.

Question 4:
An activated AED does not promptly analyze the rhythm. What is your next action?
A. Begin chest compressions.
B. Discontinue the resuscitation attempt.
C. Check all AED connections and reanalyze.
D. Rotate AED electrodes to an alternate position.
ANSWER : A — Begin chest compressions.
Explanation: Minimizing interruptions in chest compressions is a core principle of high-quality CPR. If the AED
fails to analyze the rhythm promptly, you should not delay resuscitation; resume chest compressions immediately
while troubleshooting the device.
Question 5:
You have completed 2 minutes of CPR. The ECG monitor displays a non-shockable rhythm (such
as PEA or asystole), and the patient has no pulse. Another member of your team resumes chest
compressions, and an IV is in place. What management step is your next priority?
A. Give 0.5 mg of atropine.
B. Insert an advanced airway.
C. Administer 1 mg of epinephrine.
D. Administer a dopamine infusion.
ANSWER : C — Administer 1 mg of epinephrine.
Explanation: During cardiac arrest, epinephrine 1 mg IV/IO is the standard vasopressor administered every 3 to
5 minutes to improve coronary and cerebral perfusion pressure. Atropine is no longer recommended for cardiac
arrest. Dopamine is used for post-ROSC bradycardia or shock. An advanced airway is a secondary consideration.
