What does the MARCH assessment focus on during a CBRN situation?

The MARCH assessment is a systematic approach used in combat and CBRN (Chemical, Biological, Radiological, and Nuclear) situations focused on identifying and treating life-threatening conditions that require immediate attention. The acronym MARCH stands for Massive hemorrhage, Airway, Respiratory distress, Circulation, and Head injury/hypothermia.

In a CBRN scenario, casualties may be exposed to harmful agents that can exacerbate life-threatening injuries or create new emergencies, making it critical to address these issues quickly and efficiently. By focusing on life-threatening conditions, the MARCH assessment ensures that the most critical injuries are prioritized, which is essential in a high-stress environment where time is often limited.

The other options, while relevant to patient care, are not the primary focus of the MARCH assessment. Management of respiratory distress is part of the MARCH framework but is not the sole focus. Evaluating the mental state of the casualty and assessing mobility are important aspects of overall patient assessment but do not pertain directly to the life-threatening conditions addressed in MARCH.
