PAC stands for which of the following?

• A. Post-Arrest Care
• B. Post-Action Care
• C. Post-Arrest Conditioning
• D. Pre-Arrest Care

Answer: (A)

Post-Arrest Care is the phase of management that follows the return of spontaneous circulation after an arrest event. The main idea is to stabilize the patient and optimize outcomes by addressing airway, breathing, and circulation, while preventing secondary injury to the brain and organs. This includes ensuring adequate oxygenation and ventilation, maintaining stable blood pressure and perfusion with fluids and, if needed, vasopressors, correcting metabolic and acid-base disturbances, and treating reversible causes of arrest (such as hypoxia, hypoglycemia, or tamponade). It also involves targeted temperature management when appropriate and initiating definitive therapies (like coronary reperfusion) as indicated. This terminology—post-arrest care—is the standard way clinicians describe the comprehensive care needed after ROSC, making it the best choice. The other options don’t reflect established terminology: post-action care isn’t a recognized phase in resuscitation, post-arrest conditioning isn’t the standard label, and pre-arrest care refers to prevention before an arrest occurs, not the care after.
