  1. A patient develops cardiac arrest during an electrophysiology procedure. The team suspects catheter-induced VF. The defibrillator is immediately available. What is the FIRST action?

    Answer: Defibrillate immediately without preceding CPR

    For witnessed, monitored VF (such as in-hospital or during a procedure), immediate defibrillation without preceding CPR is indicated as the defibrillator is immediately available.

  2. Which of the following best describes the correct hand placement for adult chest compressions during CPR?

    Answer: Heel of one hand on the lower half of the sternum, other hand on top interlaced

    Compressions are performed with the heel of one hand on the lower half of the sternum, with the other hand on top and fingers interlaced to deliver effective force.

  3. A patient with known Wolff-Parkinson-White (WPW) syndrome presents with rapid atrial fibrillation at 220 bpm and is hemodynamically stable. Which drug is CONTRAINDICATED?

    Answer: Adenosine

    Adenosine is contraindicated in pre-excited AF (WPW + AF) because it can block the AV node and accelerate conduction through the accessory pathway, causing VF.

  4. In the management of acute stroke identified during post-cardiac arrest care, what is the recommended timeframe for CT imaging to guide thrombolytic therapy decisions?

    Answer: Within 25 minutes of hospital arrival (door-to-CT)

    AHA/ASA guidelines recommend a door-to-CT time of ≤25 minutes to guide rapid stroke treatment decisions including thrombolytic eligibility.

  5. What is the recommended depth of chest compressions for an adult during high-quality CPR?

    Answer: At least 2 inches (5 cm), not exceeding 2.4 inches (6 cm)

    Adult chest compressions should be at least 2 inches (5 cm) deep but should not exceed 2.4 inches (6 cm) to avoid injury and maximize perfusion.

  6. A patient in refractory cardiogenic shock following ROSC is not responding to vasopressors. Which mechanical circulatory support device is most commonly considered in this scenario?

    Answer: Extracorporeal membrane oxygenation (ECMO)

    VA-ECMO (venoarterial extracorporeal membrane oxygenation) provides full cardiopulmonary support and is the preferred device for refractory cardiogenic shock post-arrest when other measures fail.

  7. During ACLS management of a patient in PEA, the team identifies severe hyperkalemia as the likely cause. Which intervention directly antagonizes the cardiac membrane effects of hyperkalemia?

    Answer: Calcium chloride 1 g IV (or calcium gluconate 3 g IV)

    Calcium chloride or gluconate directly stabilizes the cardiac membrane against the toxic effects of hyperkalemia and acts within minutes.
