After taking an appropriate history, which sign of worsening traumatic brain injury should you watch for?

• A. Increased heart rate
• B. Severe headache
• C. Clear fluid leaking from the nose
• D. Dilated pupils

Answer: (C)

In the context of traumatic brain injuries (TBI), watching for clear fluid leaking from the nose is a critical sign that indicates a worsening condition. This fluid might be cerebrospinal fluid (CSF), which could suggest a breach in the protective barriers surrounding the brain, often due to a skull fracture or other serious injury. The presence of clear fluid can indicate that the injury could potentially be life-threatening and requires immediate medical attention. Increased heart rate, while it can be associated with various medical conditions, is not a specific indicator of worsening TBI and can result from factors unrelated to brain injury, such as pain or anxiety. A severe headache can also be somewhat common after a head injury, depending on severity, but it doesn’t necessarily indicate that the condition is worsening. Dilated pupils can indicate possible pressure on the brain or a change in neurological status, but without other accompanying symptoms, such as clear fluid leakage, it may not be as definitive in signaling a progression of injury as the presence of CSF would be. Thus, monitoring for clear fluid from the nose is vital for identifying critical changes in a patient with a TBI.
