  1. A 70-year-old patient is in asystole. After confirming the rhythm in two leads, what is the correct immediate action?

    Answer: Begin high-quality CPR and administer epinephrine

    Asystole is a non-shockable rhythm; treatment is high-quality CPR with epinephrine every 3–5 minutes and search for reversible causes.

  2. Which of the following represents the correct interpretation of a QTc interval greater than 500 ms?

    Answer: Significantly prolonged, associated with risk of Torsades de Pointes

    A QTc >500 ms significantly increases the risk of Torsades de Pointes, a life-threatening polymorphic ventricular tachycardia.

  3. The treatment of choice for Torsades de Pointes (TdP) in a hemodynamically stable patient is:

    Answer: Magnesium sulfate 1–2g IV over 5–20 minutes

    Magnesium sulfate 1–2g IV is the first-line treatment for TdP as it suppresses the triggered activity causing the arrhythmia.

  4. Which statement about performing CPR on a pregnant patient in cardiac arrest is correct?

    Answer: Manually displace the uterus to the left while performing standard CPR

    Left uterine displacement (LUD) relieves aortocaval compression and improves venous return during CPR in pregnancy.

  5. A patient presents with bradycardia at 38 bpm, hypotension, and diaphoresis. Atropine 0.5mg IV fails to improve the rate. What is the next most appropriate intervention?

    Answer: Initiate transcutaneous pacing

    When atropine fails for symptomatic bradycardia, transcutaneous pacing is the next indicated intervention per ACLS guidelines.

  6. Which of the following best describes the mechanism of action of amiodarone in ventricular arrhythmias?

    Answer: Multi-channel blocker that prolongs the action potential and refractory period

    Amiodarone blocks sodium, potassium, and calcium channels and also has beta-blocking properties, prolonging the action potential duration.

  7. In a patient with STEMI, which of the following represents the goal door-to-balloon time for primary PCI at a PCI-capable hospital?

    Answer: 90 minutes

    The AHA/ACC guideline recommends door-to-balloon time of 90 minutes or less for primary PCI in STEMI patients.
