AHA ACLS 2025 Exam with Questions and Answers
Graded A+
A patient with sinus bradycardia and a heart rate of 42/min has diaphoresis and a blood
pressure of 80/60 mm Hg. What is the initial dose of atropine?
1mg
A patient is in pulseless ventricular tachycardia. Two shocks and 1 dose of epinephrine have
been given. Which drug should be given next?
Amiodarone 300mg
A patient has a rapid irregular wide-complex tachycardia. The ventricular rate is 138/min. He
is asymptomatic, with a blood pressure of 110/70 mm Hg. He has a history of angina. What
action is recommended next?
Seek expert consultation
What is the indication for the use of magnesium in cardiac arrest?
Pulseless ventricular tachycardia-associated
VA patient with STEMI has ongoing chest discomfort. Heparin 4000 units IV bolus and a
heparin infusion of 1000 units per hour are being administered. The patient did not take
aspirin because he has a history of gastritis, which was treated 5 years ago. What is your next
action?
Give aspirin 162-325mg to chew
A monitored patient in the ICU developed a sudden onset of narrow-complex tachycardia at a
rate of 220/min. The patient's blood pressure is 128/58 mm Hg, the PETCO2 is 38 mm Hg, and
the pulse oximetry reading is 98%. There is vascular access in the left arm, and the patient has
not been given any vasoactive drugs. A 12-lead ECG confirms a supraventricular tachycardia
with no evidence of ischemia or infarction. The heart rate has not responded to vagal
maneuvers. What is your next action?
, Administer 6mg Adenosine IV push
A patient has sinus bradycardia with a heart rate of 36/min. Atropine has been administered
to a total dose of 3 mg. A transcutaneous pacemaker has failed to capture. The patient is
confused, and her blood pressure is 88/56 mm Hg. Which therapy is now indicated?
Epi 2-10 mcg/min
Which intervention is most appropriate for the treatment of a patient in asystole?
Epi
A patient with possible STEMI has ongoing chest discomfort. What is a contraindication to
nitrate administration?
Use of a phosphodiesterase within the previous 24 hours
You arrive on the scene with the code team. High-quality CPR is in progress. An AED has
previously advised "no shock indicated." A rhythm check now finds asystole. After resuming
high-quality compressions, which action do you take next?
Establish IV/IO access
A patient is in cardiac arrest. Ventricular fibrillation has been refractory to an initial shock. If
no pathway for medication administration is in place, which method is preferred?
IV/IO
A patient is in cardiac arrest. Ventricular fibrillation has been refractory to a second shock.
Which drug should be administered first?
Epi 1mg IV/IO
A patient is in refractory ventricular fibrillation. High-quality CPR is in progress. One dose of
epinephrine was given after the second shock. An antiarrhythmic drug was given immediately
after the third shock. You are the team leader. Which medication do you order next?
Epi 1mg
