This Exam contains:
➢ 50 Questions and Answers

➢ Each Question Includes The Correct Answer
➢ Rationale That Aligns with ACLS 2025 Principles.
,1. What is the recommended initial dose of adenosine for the management
of supraventricular tachycardia unresponsive to vagal maneuvers?
A) 12 mg IV
B) 6 mg IV
C) 9 mg IV
D) 3 mg IV
Answer: B) 6 mg IV
Explanation: The initial adenosine dose for SVT resistant to vagal
maneuvers is 6 mg rapid IV push, followed by a saline flush. This rapid
administration is crucial due to the drug's very short half-life and immediate
effect on AV nodal conduction.

2. What is the recommended follow-up dose of adenosine for management
of supraventricular tachycardia unresponsive to the first adenosine dose?
A) 12 mg IV
B) 6 mg IV
C) 9 mg IV
D) 3 mg IV
Answer: A) 12 mg IV
Explanation: If the initial 6 mg dose does not terminate SVT, a second dose
of 12 mg can be administered after 1 to 2 minutes. This dose may be
repeated once.
---
,3. If the patient is conscious, establish IV access prior to synchronized
cardioversion and administer:
A) an antiarrhythmic
B) sedation
C) a B-adrenergic agonist
D) an antiemetic
Answer: B) sedation
Explanation: Conscious patients undergoing synchronized cardioversion
should be sedated to minimize pain and anxiety, improving patient tolerance
and safety.
---
4. What rhythm is shown on the monitor?
A) Sinus rhythm
B) Supraventricular tachycardia
C) Ventricular fibrillation
D) Ventricular tachycardia
Answer: B) Supraventricular tachycardia
Explanation: A regular narrow complex tachycardia at 180 bpm typically
represents SVT.

5. What do your next steps include?
A) IV access
B) 12-lead ECG
C) Synchronized cardioversion
D) Administer amiodarone
E) Vagal maneuvers
Answer: A) IV access and E) Vagal maneuvers
Explanation: Establish IV access and attempt vagal maneuvers as initial
treatment for stable SVT before medication or electrical cardioversion.
---
6. Which is a contraindication to the use of procainamide infusion in the
management of stable wide-complex tachycardia?
A) Impaired renal function
B) Type 2 diabetes
C) Prolonged QT interval
D) Asthma
Answer: C) Prolonged QT interval
Explanation: Procainamide prolongs QT interval and is contraindicated in
patients with existing prolonged QT to avoid torsades de pointes.
---
, 7. What is the recommended first dose of amiodarone for the management
of stable wide-complex tachycardia?
A) 300 mg IV
B) 2-4 mg/kg IV
C) 100 mg IV
D) 150 mg IV
Answer: D) 150 mg IV
Explanation: For stable wide-complex tachycardia, amiodarone is
administered as a 150 mg intravenous infusion over 10 minutes. The 300 mg
dose is used in cardiac arrest scenarios.
---
8. A 72-year-old male patient is conscious and alert with HR 180/min, weak
radial pulse, BP 110/78 mmHg, and SpO2 96%. What are the most
appropriate interventions?
A) Administer adenosine
B) Administer epinephrine
C) Maintain a patent airway and monitor
D) Attach a 12-lead ECG
Answer: D) Attach a 12-lead ECG
Explanation: A 12-lead ECG is critical for diagnosing the arrhythmia before
treatment, especially with symptoms of palpitations and dizziness.

9. Would you consider the patient stable or unstable?
