What does secondary injury prevention in TBI revolve around?

• A. Preventing hypoxia, hypotension, fever, edema, seizures and other secondary insults
• B. Reducing infection risk only
• C. Avoiding caffeine intake
• D. Limiting physical therapy initiation

Answer: (A)

In TBI, secondary injury prevention targets stopping processes that can worsen brain damage after the initial injury. The brain remains vulnerable to new insults such as low oxygen or blood flow (hypoxia and hypotension), fever, edema that raises pressure, and seizures. Each of these can push the brain from a state of recovery into further injury, so the goal is to prevent them and other insults from occurring or escalating. The option that explicitly lists preventing hypoxia, hypotension, fever, edema, seizures and other secondary insults captures this broad protective aim. In practice, this means measures like ensuring adequate airway and oxygenation, maintaining blood pressure to preserve cerebral perfusion, controlling fever, preventing and treating seizures, and managing edema and intracranial pressure. Choices that focus only on infection, or on unrelated factors like caffeine or timing of rehabilitation, don’t address the main goal of limiting secondary brain injury.
