For a patient with suspected head injury and altered mental status, which field priorities should guide care?

• A. Immediate imaging in field
• B. Evacuate without treatment
• C. Focus on pain control first
• D. Ensure airway and breathing, stabilize the cervical spine, maintain adequate perfusion, and avoid hypotension

Answer: (D)

The main idea being tested is that in a patient with head injury and altered mental status, the immediate field priorities are securing the airway, ensuring adequate breathing, maintaining circulation and perfusion, and stabilizing the cervical spine to prevent secondary brain injury. Airway protection and oxygenation are crucial because hypoxia and poor ventilation rapidly worsen brain injury, and cervical spine stabilization prevents further injury during airway maneuvers and transport. Maintaining perfusion means avoiding hypotension so the brain continues to receive blood flow, which is essential for outcomes after a head injury. These steps form the primary survey in trauma care and set the stage for any downstream interventions like imaging.

In practice, this means promptly assessing and securing the airway (with cervical spine protection), ensuring effective breathing, controlling any bleeding to support circulation, and transporting the patient with spinal precautions while monitoring and maintaining adequate blood pressure. Imaging or definitive field treatments should come after these life-sustaining actions.

Other approaches neglect the most critical first steps. Jumping straight to imaging in the field doesn’t address airway, breathing, and perfusion, and could endanger the patient. Evacuating without treatment skips essential stabilization. Prioritizing pain control before securing the airway can delay oxygenation and perfusion, worsening brain injury.
