What is the recommended initial trauma assessment framework used in the field?

• A. ABC (Airway, Breathing, Circulation)
• B. FAST
• C. MIST
• D. ABCDE (Airway, Breathing, Circulation, Disability, Exposure)

Answer: (D)

In field trauma care the initial assessment follows a structured primary survey called ABCDE: Airway with cervical spine protection, Breathing, Circulation, Disability, and Exposure. This order targets the most immediate life threats first. Securing the airway is the top priority because without a patent airway, oxygen cannot reach the lungs and all other interventions become moot. After the airway is addressed, you evaluate and support breathing to ensure adequate ventilation and oxygen delivery. Then you assess circulation to control visible and hidden bleeding and confirm perfusion, because massive blood loss or shock can rapidly endanger life. Quick Disability assessment (neurologic status) helps you recognize brain injury and guides ongoing monitoring and treatment. Finally, Exposure means you fully inspect for injuries while preventing hypothermia, ensuring you don’t miss injuries concealed under clothing or blankets. This framework is especially crucial in the field where imaging isn't immediately available and decisions must be made rapidly and systematically.

The other options don’t provide the complete, repeatable primary survey used in field trauma. A simple Airway-Breathing-Circulation approach omits the neurological status and exposure steps. FAST is a diagnostic tool used to detect intra-abdominal bleeding, not a full primary survey. MIST is a separate prehospital data collection framework, not the standard for the initial trauma assessment.
