Which condition is included as the final category in the MARCH mnemonic?

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

Answer: (A)

In MARCH, the final focus is addressing head injury and hypothermia. The mnemonic starts with Massive hemorrhage, then Airway, then Respiration, then Circulation, and finally Hypothermia/Head injury. After you’ve stopped bleeding and secured the airway, breathing, and circulation, the next critical concern is preventing heat loss and monitoring for potential head injury. Hypothermia worsens bleeding by impairing coagulation and can amplify brain injury if a head injury is present, so protecting the head and keeping the patient warm helps prevent secondary damage. Placing hypothermia/head injury as the last category reflects that those issues are addressed once the most immediate life threats have been stabilized. So the final category is head injury and hypothermia.
