Which signs indicate deterioration with head injuries during PCC?

• A. Decreased level of consciousness
• B. Unequal pupils
• C. Agitation or somnolence
• D. All of the above

Answer: (D)

In head injuries during prolonged casualty care, three red flags signal deterioration: changes in mental status, unequal pupils, and new agitation or drowsiness. A decreasing level of consciousness shows the brain isn’t functioning at baseline and may reflect swelling, bleeding, or reduced oxygen delivery; it calls for airway protection, careful monitoring, and rapid transport. Unequal pupils point to potential increased intracranial pressure or brain injury on one side; check pupil size on both eyes and look for a pupil that becomes fixed and dilated, then act quickly to evacuate and avoid actions that could worsen pressure. Agitation or somnolence indicates altered cerebral function—agitation can raise pressure in the brain, while excessive sleepiness can mean hypoxia or worsening injury; respond by ensuring the airway is clear, reducing unnecessary stimuli, and expediting definitive care. Because any one of these signs can herald worsening injury, all of them together represent the full set of indicators you’d watch for in PCC.
