ACLS Provider Exam Questions and Answers
(Latest ) – Verified AHA Study Guide
& Megacode Solutions




Question 1: You find an unresponsive male lying on the floor gasping for air (agonal
breaths). After activating the emergency response team, what step should you take
next?
 A. Begin rescue breathing only
 B. Simultaneously check for a pulse and breathing for no more than 10 seconds
 C. Deliver 2 fast rescue breaths
 D. Obtain an immediate 12-lead ECG

, 🟢 Correct Answer: B
 Explanation: Agonal gasps do not count as normal breathing. You must check for a
carotid pulse and chest rise simultaneously for 5 to 10 seconds before starting chest
compressions.




Question 2: During CPR with no advanced airway in place, what is the correct
compression-to-ventilation ratio for an adult patient?
 A. 15:2
 B. 5:1
 C. 30:2
 D. Continuous compressions with 10 breaths per minute
🟢 Correct Answer: C
 Explanation: For all adult cardiac arrest scenarios without an advanced airway, the
universal ratio is 30 chest compressions followed by 2 rescue breaths.




Question 3: To properly ventilate an adult patient in respiratory arrest who has a
perfusing pulse, how often should you deliver rescue breaths?
 A. Once every 3 seconds
 B. Once every 6 seconds
 C. Once every 10 seconds
 D. Twice every 5 seconds
🟢 Correct Answer: B
 Explanation: Current guidelines recommend delivering 1 breath every 6 seconds (10
breaths per minute) for an adult with a pulse to avoid hyperventilation.

Question 4: A patient remains in ventricular fibrillation (V-Fib) despite receiving 1 shock
and 2 minutes of continuous high-quality CPR. An IV line is established. What is your
next priority intervention?
 A. Administer Amiodarone 300 mg IV push

,  B. Administer Epinephrine 1 mg IV push
 C. Deliver a synchronized cardioversion shock
 D. Inject Atropine 0.5 mg IV push
🟢 Correct Answer: B
 Explanation: In the shockable arrest algorithm (V-Fib/Pulseless VT), Epinephrine 1 mg
is given after the second shock and then every 3 to 5 minutes. Amiodarone is given
later, after the third shock.




Question 5: You have completed 2 minutes of CPR on a cardiac arrest patient. During
a pause, the monitor shows asystole, and the patient has no pulse. What is the
immediate next action?
 A. Terminate all resuscitative efforts
 B. Charge the defibrillator and deliver a 200J shock
 C. Resume chest compressions immediately
 D. Prepare a dopamine infusion
🟢 Correct Answer: C
 Explanation: Asystole is a non-shockable rhythm. Delivering a shock is harmful. You
must immediately resume chest compressions to maintain coronary perfusion. [1, 2]




Question 6: Which action is recommended to optimize high-quality CPR and minimize
interruptions in chest compressions during a rhythm check?
 A. Stop CPR immediately when the AED arrives
 B. Continue CPR while the defibrillator charges
 C. Only perform pulse checks every 30 seconds
 D. Check the pulse after every advanced airway breath
🟢 Correct Answer: B
 Explanation: To keep the chest compression fraction as high as possible, providers
should continue compressions while the defibrillator is actively charging.
