In MARCH, what does the M represent?

• A. Mechanical Injury
• B. Medical Assessment
• C. Massive Hemorrhage
• D. Mission Critical

Answer: (C)

Massive hemorrhage is the first priority in the MARCH framework because uncontrolled bleeding is the most immediate and life-threatening danger in many trauma situations. In battlefield and high-risk settings, a casualty can bleed out in minutes if bleeding isn’t stopped quickly, so the very first action is to identify and control massive bleeding. This means applying direct pressure, using tourniquets for limb injuries, and employing hemostatic dressings or wound packing as appropriate. By addressing the most lethal threat first, you buy time for airway and breathing interventions and for proper circulation and temperature management to follow.

So, the M stands for Massive Hemorrhage, signaling that bleeding control comes before other steps like airway management or breathing support. The other concepts listed—mechanical injury, medical assessment, or mission-critical considerations—don’t define what the M represents in this acronym.
