Sample Questions and Answers for ACLS Exam Version C

To help you prepare for ACLS Exam Version C, here are sample questions and detailed explanations of the answers. These questions cover various topics and reflect the types of scenarios you may encounter.

Question 1:

A 60-year-old male is brought to the emergency department complaining of chest pain. His ECG shows ST-segment elevation in leads II, III, and aVF. What is the most appropriate initial treatment?

A) Administer aspirin and oxygen.

B) Administer nitroglycerin and morphine.

C) Prepare for immediate PCI (percutaneous coronary intervention).

D) Administer a beta-blocker.

Answer:

A) Administer aspirin and oxygen.

Explanation:

The patient's ECG indicates an acute inferior ST-elevation myocardial infarction (STEMI). The initial management should focus on providing supportive care and initiating treatments that can improve outcomes.

• Aspirin: Reduces platelet aggregation and the risk of further clot formation.
• Oxygen: Ensures adequate oxygenation, particularly if the patient is hypoxic.

While nitroglycerin and morphine (B) may be used, aspirin and oxygen are the immediate priorities. PCI (C) is a definitive treatment but requires coordination and preparation. Beta-blockers (D) are generally avoided in the acute phase of STEMI, especially if there are signs of heart failure or hemodynamic instability.

Question 2:

During a cardiac arrest, you administer epinephrine. What is the correct dose and route of administration?

A) 1 mg IV/IO every 3-5 minutes.

B) 0.5 mg IV/IO every 5 minutes.

C) 2 mg IV/IO every 3 minutes.

D) 1 mg IM every 3-5 minutes.

Answer:

A) 1 mg IV/IO every 3-5 minutes.

Explanation:

Epinephrine is a key medication in cardiac arrest management. The correct dose for adults is 1 mg administered intravenously (IV) or intraosseously (IO) every 3-5 minutes. Epinephrine's alpha-adrenergic effects cause vasoconstriction, which increases coronary and cerebral perfusion pressure during CPR.

Question 3:

A patient is in ventricular tachycardia (VT) with a pulse. The patient is hypotensive and showing signs of shock. What is the most appropriate initial treatment?

A) Amiodarone.

B) Synchronized cardioversion.

C) Adenosine.

D) Magnesium sulfate.

Answer:

B) Synchronized cardioversion.

Explanation:

The patient is in unstable VT (hypotension and signs of shock). Synchronized cardioversion is the treatment of choice for unstable VT with a pulse. This involves delivering a controlled electrical shock that is synchronized with the patient’s R wave to avoid inducing ventricular fibrillation. Amiodarone (A) may be considered if the patient is stable or if cardioversion is unsuccessful. Adenosine (C) is used for supraventricular tachycardia (SVT). Magnesium sulfate (D) is used for Torsades de Pointes.

Question 4:

A patient is in asystole. After confirming the rhythm and ensuring proper lead placement, what is the next immediate action?

A) Administer epinephrine.

B) Perform immediate defibrillation.

C) Administer amiodarone.

D) Check for reversible causes (Hs and Ts).

Answer:

A) Administer epinephrine.

Explanation:

In asystole, the ACLS algorithm emphasizes the importance of administering epinephrine and continuing high-quality CPR. Asystole is not a shockable rhythm, so defibrillation (B) is not indicated. Amiodarone (C) is used for shockable rhythms, not asystole. Checking for reversible causes (Hs and Ts) is important, but the immediate action is to administer epinephrine.

Question 5:

A patient is in atrial fibrillation with a rapid ventricular rate. The patient is stable. What is the most appropriate initial treatment?

A) Synchronized cardioversion.

B) Administer adenosine.

C) Administer a calcium channel blocker or beta-blocker.

D) Perform immediate defibrillation.

Answer:

C) Administer a calcium channel blocker or beta-blocker.

Explanation:

For a stable patient in atrial fibrillation with a rapid ventricular rate, the goal is to control the heart rate. Calcium channel blockers (such as diltiazem or verapamil) and beta-blockers (such as metoprolol or esmolol) are commonly used to slow the ventricular rate. Synchronized cardioversion (A) is reserved for unstable patients. Adenosine (B) is used for SVT. Defibrillation (D) is not indicated for atrial fibrillation.
