What does the MARCH protocol stand for in TCCC?

The MARCH protocol is a systematic approach used in Tactical Combat Casualty Care (TCCC) to address life-threatening conditions in injured individuals. The correct answer outlines the key components that prioritize the care of casualties in a combat setting.

"Massive hemorrhage" refers to immediate action required to control severe bleeding, which is the leading cause of preventable death on the battlefield. The protocol emphasizes rapid assessment and intervention to manage this critical issue first. Following that, "Airway" ensures that a clear airway is maintained, which is essential for oxygenation and preventing asphyxiation.

"Respiration" pertains to evaluating and managing the casualty’s breathing, making sure that effective ventilation is taking place. This is followed by "Circulation," which involves assessing and maintaining blood circulation to support vital organ function. Lastly, "Head injury/hypothermia" addresses the potential complications that can arise from head trauma or exposure to temperature extremes, ensuring comprehensive care for the casualty.

Overall, while other choices present similar medical terms, they do not accurately represent the MARCH acronym used within TCCC, making the correct answer one that adheres specifically to the established standards for prioritizing trauma care in tactical scenarios.
