Based on the 2025-2026 AHA Advanced Cardiovascular Life Support (ACLS) guidelines,
this comprehensive answer key provides correct answers with detailed explanations for
ACLS post-test and practice exam questions.
Part 1: Initial Assessment & High-Quality CPR
Question 1
You find an unresponsive patient who is not breathing. After activating the
emergency response system, you determine there is no pulse. What is your next
action?
A) Apply the AED
B) Open the airway
C) Start chest compressions at a rate of at least 100 per minute
D) Check for a medical alert bracelet
Correct Answer: C) Start chest compressions at a rate of at least 100 per minute
Explanation: The correct sequence for an unresponsive patient with no pulse and no
breathing is to activate emergency response, then immediately begin high-quality chest
,compressions. Early CPR, starting with compressions, is the priority before applying an
AED or checking for other issues.
Question 2
You are evaluating a 58-year-old man with chest pain. The BP is 92/50 mm Hg,
heart rate is 92/min, respiratory rate is 14 breaths/min, and pulse oximetry is 97%.
What assessment step is most important now?
A) Administer nitroglycerin
B) Obtain a 12-lead ECG
C) Start an IV line
D) Administer morphine for pain
Correct Answer: B) Obtain a 12-lead ECG
*Explanation: For a patient with chest pain, obtaining a 12-lead ECG is the priority to
identify ST-segment elevation myocardial infarction (STEMI) or other acute coronary
syndrome patterns. The ECG should be obtained within 10 minutes of arrival.*
Question 3
Which action is a component of high-quality chest compressions?
A) Leaning on the chest between compressions
B) Allowing complete chest recoil after each compression
C) Compressing the chest at a depth of 1.5 inches
D) Interrupting compressions every 30 seconds for pulse checks
Correct Answer: B) Allowing complete chest recoil after each compression
Explanation: Complete chest recoil allows the heart to refill with blood between
compressions. Leaning on the chest prevents recoil, reduces venous return, and decreases
cardiac output. High-quality CPR requires allowing complete recoil after each
compression.
,Question 4
What is a common but sometimes fatal mistake in cardiac arrest management?
A) Providing excessive ventilation (hyperventilation)
B) Delivering epinephrine too early
C) Using the AED too quickly
D) Checking the pulse after every compression cycle
Correct Answer: A) Providing excessive ventilation (hyperventilation)
Explanation: Hyperventilation increases intrathoracic pressure, decreases venous return,
reduces cardiac output, and decreases coronary and cerebral perfusion. This is a common
and potentially fatal error in cardiac arrest management.
Question 5
What is the appropriate ventilation strategy for an adult in respiratory arrest with
a pulse of 80 beats/min?
A) 1 breath every 3-4 seconds
B) 1 breath every 5-6 seconds
C) 1 breath every 8-10 seconds
D) 1 breath every 12 seconds
Correct Answer: B) 1 breath every 5-6 seconds
*Explanation: For an adult patient with a perfusing rhythm (pulse present) who requires
bag-mask ventilation, the recommended rate is 1 breath every 5 to 6 seconds (10-12
breaths per minute). This rate avoids hyperventilation while maintaining adequate
oxygenation.*
Question 6
, What is the purpose of a medical emergency team or rapid response team?
A) Improving care for patients admitted to critical care units
B) Improving patient outcomes by identifying and treating early clinical deterioration
C) Providing diagnostic consultation to emergency department patients
D) Providing online consultation to EMS personnel in the field
Correct Answer: B) Improving patient outcomes by identifying and treating early
clinical deterioration
Explanation: Rapid Response Teams (RRTs) or Medical Emergency Teams (METs) are
designed to identify and intervene early when patients show signs of clinical deterioration
before cardiac arrest occurs. This proactive approach has been shown to reduce in-hospital
cardiac arrest rates.
Question 7
What is the recommended compression rate for high-quality CPR?
A) 60 to 80 compressions per minute
B) 80 to 100 compressions per minute
C) 100 to 120 compressions per minute
D) 120 to 140 compressions per minute
Correct Answer: C) 100 to 120 compressions per minute
*Explanation: The AHA recommends a compression rate of 100 to 120 compressions per
minute. Rates slower than 100/min do not generate adequate blood flow, and rates
faster than 120/min reduce compression depth due to incomplete chest recoil.*
Question 8
Which action increases the chance of successful conversion of ventricular
fibrillation?
