Which component of MARCH is addressed last?

• A. Hypothermia/Head injury
• B. Airway
• C. Circulation
• D. Massive hemorrhage

Answer: (A)

In this approach, immediate threats to life are tackled in a precise order, so the last element addressed is the prevention and management of hypothermia and head injury. Massive hemorrhage is tackled first because uncontrolled bleeding is the most life‑threatening in the field. After that, securing the airway ensures the patient can breathe and receive adequate oxygen. Then you focus on respiration and circulation to maintain gas exchange and perfusion. Only after these critical issues are stabilized do you shift attention to preventing hypothermia and evaluating head injuries. Hypothermia can worsen bleeding through impaired coagulation and complicate recovery, and head injuries require careful monitoring once the most urgent threats are managed, which is why they’re addressed last.
