ACLS Final Test Questions and Answers: A Comprehensive Study Guide
Introduction
The Advanced Cardiovascular Life Support (ACLS) certification is a cornerstone for clinicians who manage acute cardiac emergencies. The final exam, typically a multiple‑choice test, evaluates knowledge of advanced cardiac life‑support algorithms, pharmacology, and clinical decision‑making. Mastering the exam not only earns the credential but also sharpens the skills needed to save lives in the emergency department, ICU, or operating room. This guide presents a curated set of representative ACLS final test questions, complete answers, and explanations that highlight the reasoning behind each correct choice. By studying these examples, you’ll reinforce key concepts and improve test‑taking strategy.

2. Sample ACLS Final Test Questions
Below are 15 representative questions that mirror the difficulty and content of the actual exam. Each question is followed by the answer and a concise explanation.
Question 1 – Algorithmic Decision Making
A 68‑year‑old man presents with sudden chest pain and an irregular heart rate. ECG shows ventricular tachycardia (VT) with a pulse. What is the first step in management?
A) Immediate synchronized cardioversion
B) Intravenous amiodarone 150 mg
C) Cardiac catheterization
D) Intravenous lidocaine 1 mg/kg
Answer: A) Immediate synchronized cardioversion
Explanation: VT with a pulse is stable if the patient is hemodynamically stable. The first line is synchronized cardioversion (energy 100 J biphasic). Amiodarone or lidocaine are second‑line drugs; catheterization is for underlying ischemia.
Question 2 – Pharmacology
Which drug is contraindicated in a patient with a history of prolonged QT interval presenting with torsades de pointes?
A) Amiodarone
B) Magnesium sulfate
C) Lidocaine
D) Procainamide
Answer: A) Amiodarone
Explanation: Amiodarone prolongs the QT interval and can worsen torsades. Magnesium sulfate is the first‑line treatment Practical, not theoretical..
Question 3 – Advanced Airway
A trauma patient with a GCS of 9 requires intubation. Which adjunct should be used to improve first‑pass success?
A) Rapid sequence induction (RSI)
B) Awake fiberoptic intubation
C) Laryngeal mask airway (LMA)
D) Nasotracheal intubation
Answer: A) Rapid sequence induction (RSI)
Explanation: RSI provides rapid paralysis and cricoid pressure, reducing aspiration risk and increasing first‑pass success in unconscious trauma patients But it adds up..
Question 4 – Cardiogenic Shock
A 55‑year‑old woman with anterior STEMI develops cardiogenic shock. Which drug should be started immediately?
A) Norepinephrine 0.01 µg/kg/min
B) Dopamine 5 µg/kg/min
C) Epinephrine 0.5 µg/kg/min
D) Phenylephrine 50 µg/min
Answer: A) Norepinephrine 0.01 µg/kg/min
Explanation: Norepinephrine is the first‑line vasopressor in cardiogenic shock, improving MAP while minimizing tachycardia.
Question 5 – Defibrillation Threshold
A patient with ventricular fibrillation (VF) receives a 200‑J biphasic shock. What is the next step if the rhythm remains VF?
A) Immediate repeat 200‑J shock
B) Administer 300 mg epinephrine IV
C) Deliver a 150‑J shock
D) Initiate CPR and give 300 mg epinephrine
Answer: A) Immediate repeat 200‑J shock
Explanation: After a successful shock, CPR should be withheld if the rhythm is still VF; the next step is repeat shock at the same energy until ROSC or rhythm conversion.
Question 6 – Pharmacologic Dose
What is the correct intravenous dose of epinephrine for a patient in pulseless electrical activity (PEA) arrest?
A) 1 mg every 3–5 min
B) 0.5 mg every 5 min
C) 2 mg every 3 min
D) 0.1 mg every 3 min
Answer: A) 1 mg every 3–5 min
Explanation: ACLS protocol recommends 1 mg IV/IO epinephrine every 3–5 minutes during advanced cardiac life support.
Question 7 – Bundle‑Care
Which of the following is part of the “Rapid‑Sequence Intubation” bundle for trauma patients?
A) Pre‑oxygenation with 100 % O₂ for 3 min
B) Administration of 0.2 mg/kg ketamine
C) Use of a gum elastic bougie
D) Immediate cricothyrotomy
Answer: A) Pre‑oxygenation with 100 % O₂ for 3 min
Explanation: Adequate pre‑oxygenation reduces hypoxia during apnea; ketamine dosing is 1 mg/kg; bougie is an adjunct, not mandatory; cricothyrotomy is for failed intubation And that's really what it comes down to..
Question 8 – Pulseless Electrical Activity (PEA)
In a PEA arrest, which underlying condition is least likely to be the cause?
A) Hypovolemia
B) Hypoxia
C) Hyperkalemia
D) Pulmonary embolism
Answer: C) Hyperkalemia
Explanation: Hyperkalemia typically presents with arrhythmias (sine wave, VF) rather than PEA. The classic “Hs and Ts” for PEA include hypovolemia, hypoxia, hypothermia, hyperkalemia, etc., but hyperkalemia is more arrhythmogenic.
Question 9 – Post‑Cardiac Arrest Care
Which medication should be started within 24 h after ROSC in a comatose patient to reduce mortality?
A) Midazolam
B) Propofol
C) Targeted temperature management (TTM) at 33 °C
D) Vasopressin
Answer: C) Targeted temperature management (TTM) at 33 °C
Explanation: TTM improves neurologic outcomes in post‑cardiac arrest patients; sedation is used for comfort, not neuroprotection.
Question 10 – Electrical Storm
A patient with implantable cardioverter‑defibrillator (ICD) receives multiple shocks in 24 h. What is the next step?
A) Increase beta‑blocker dose
B) Implant an atrial pacing lead
C) Implant a defibrillator with antitachycardia pacing (ATP)
D) Discontinue amiodarone
Answer: A) Increase beta‑blocker dose
Explanation: Electrical storm is often managed by optimizing beta‑blockers; ATP can be considered if the device has that capability, but medication titration is first.
Question 11 – Anticoagulation Reversal
A patient on warfarin presents with a life‑threatening intracranial hemorrhage. Which agent should be administered?
A) Vitamin K 5 mg IV
B) Fresh frozen plasma (FFP) 10 mL/kg
C) Prothrombin complex concentrate (PCC) 50 IU/kg
D) Tranexamic acid 1 g IV
Answer: C) Prothrombin complex concentrate (PCC) 50 IU/kg
Explanation: PCC rapidly reverses warfarin’s effect; FFP is slower and requires larger volumes.
Question 12 – Pulmonary Embolism (PE) – Massive
A patient with massive PE develops cardiogenic shock. Which therapy is indicated?
A) Thrombolysis with alteplase 100 mg IV over 2 h
B) Heparin infusion 5000 U bolus
C) Surgical embolectomy
D) IVC filter insertion
Answer: A) Thrombolysis with alteplase 100 mg IV over 2 h
Explanation: Massive PE with shock warrants immediate thrombolysis; surgical embolectomy is a backup if thrombolysis fails.
Question 13 – Coronary Intervention Timing
A 60‑year‑old patient with STEMI arrives 90 min after symptom onset. What is the recommended reperfusion strategy?
A) Immediate thrombolysis
B) Primary percutaneous coronary intervention (PCI)
C) CABG within 24 h
D) Observation and medical therapy
Answer: B) Primary PCI
Explanation: For patients within 90 min of symptom onset, primary PCI is superior to thrombolysis when available within 120 min.
Question 14 – Hypothermia Management
A patient is found to have a core temperature of 32 °C during resuscitation. Which intervention is appropriate?
A) Rapid rewarming with heated IV fluids
B) Warm blankets only
C) No intervention needed
D) Immediate CPR
Answer: A) Rapid rewarming with heated IV fluids
Explanation: Hypothermia (<35 °C) during arrest worsens outcomes; active rewarming improves survival Less friction, more output..
Question 15 – Bradyarrhythmia – Vasovagal
A 25‑year‑old woman presents with dizziness and a heart rate of 30 bpm. ECG shows sinus bradycardia. What is the first-line treatment?
A) Atropine 0.5 mg IV
B) Dopamine infusion
C) Temporary pacemaker
D) Adenosine
Answer: A) Atropine 0.5 mg IV
Explanation: Atropine is the first‑line therapy for symptomatic bradycardia; dopamine and pacing are second‑line.
3. Key Take‑Away Points
- Follow the algorithms: The ACLS manual is your roadmap. Memorize the flowcharts for arrhythmias, shock, and resuscitation.
- Drug dosing matters: Know the exact IV doses and intervals—these are often the difference between correct and incorrect answers.
- Time is critical: Many questions hinge on the order of interventions (e.g., cardioversion before drugs in stable VT).
- Clinical reasoning: The exam tests not just recall but decision‑making under pressure. Practice case‑based scenarios.
- Stay current: ACLS updates every 3 years; ensure your study materials reflect the latest guidelines.
