What is the primary survey sequence recommended for trauma in the field?

• A. Airway with C-spine control, Breathing, Circulation, Disability, Exposure/Environmental control.
• B. Breathing, Airway, Circulation, Disability, Exposure/Environmental control.
• C. Circulation, Breathing, Airway, Disability, Exposure/Environmental control.
• D. Airway, Breathing, Disability, Circulation, Exposure.

Answer: (A)

In field trauma, the primary survey follows the ABCDE sequence: Airway with cervical spine control, Breathing, Circulation, Disability, Exposure/Environmental control. Securing the airway with in-line cervical spine stabilization is the top priority because airway compromise plus potential neck injury can rapidly kill a patient, so you address patency and neck protection at the same time. Once the airway is secured, you assess breathing to ensure adequate ventilation and oxygenation, then move to circulation to control life-threatening bleeding and verify perfusion. Quick neuro status (disability) checks follow to gauge consciousness and potential spinal injury, and finally you expose the patient to inspect for hidden injuries while preventing heat loss. Beginning with breathing or circulation would delay securing the airway and protecting the spine, which is why this sequence is best.
