Which of the following best describes secondary injury prevention in TBI care?

• A. Avoids unnecessary corticosteroids in acute TBI.
• B. Stabilize ventilation to prevent hypoxia and hypotension.
• C. Prevent fever and seizures to limit secondary injury.
• D. Protecting the brain from hypoxia, hypotension, fever, seizures, and edema.

Answer: (D)

Secondary injury prevention focuses on stopping the brain from suffering further damage after the initial injury. After the primary trauma, a cascade of harmful processes—loss of oxygen or blood flow, fever, seizures, brain swelling, and inflammation—can worsen injury if not addressed. The best description is protecting the brain from hypoxia, hypotension, fever, seizures, and edema, because it covers all major drivers that can escalate damage and worsen outcomes. In practice, this means ensuring adequate oxygenation and cerebral perfusion, controlling temperature, preventing seizures when appropriate, and managing swelling and intracranial pressure.

Other choices touch on important aspects of care but aren’t as comprehensive. Avoiding corticosteroids in acute TBI is about medication choice rather than the broader prevention of secondary injury. Stabilizing ventilation targets preventing hypoxia and hypotension but doesn’t explicitly address fever, seizures, or edema. Focusing only on fever and seizures misses the critical roles of oxygenation, perfusion, and edema control in limiting secondary injury.
