During intraoperative cardiac arrest, which of the following best describes the initial ACLS steps to initiate?

• A. Activate the code.
• B. Begin high-quality CPR, secure airway and oxygenation, attach monitor, administer epinephrine 1 mg IV every 3–5 minutes, and defibrillate per rhythm if indicated.
• C. Stop CPR after one minute.
• D. Defibrillate without performing CPR.

Answer: (B)

The main idea is that during intraoperative cardiac arrest you must act quickly to maintain perfusion and support circulation while preparing for advanced interventions. The best initial ACLS steps integrate starting high‑quality CPR right away, securing the airway and providing oxygen, attaching monitoring to identify the rhythm, giving epinephrine to improve coronary and cerebral perfusion, and defibrillating if the rhythm is shockable. This sequence reflects the ACLS approach: start compressions immediately to preserve perfusion, ensure adequate ventilation and oxygenation, and treat the underlying rhythm with medications and defibrillation as soon as a shockable rhythm is identified. Stopping CPR after one minute delays perfusion to vital organs, and defibrillating without any CPR would provide minimal perfusion during the shock. Simply activating the code is important, but it does not specify the critical steps that must be performed immediately to optimize outcomes.
