Which of the following is a sign or symptom of a possible head or brain injury?

• A. Nausea, vomiting, severe or persistent headache; problems with vision or speech
• B. Shortness of breath and chest pain
• C. Abdominal pain with vomiting
• D. Rash on the skin

Answer: (A)

Understanding signs of head or brain injury focuses on symptoms that reflect changes in brain function after trauma. Nausea, vomiting, a severe or persistent headache, and new problems with vision or speech indicate the brain may be affected—these are neurologic signs that can accompany concussion or more serious intracranial injury. They show the brain isn’t functioning normally after impact, which is why they’re the best indicators of possible head injury.

By contrast, shortness of breath and chest pain point to heart or lung issues, abdominal pain with vomiting suggests a gastrointestinal problem, and a rash is a skin finding. None of those are specific indicators of head or brain injury, which is why they’re not the best match in this context. If head trauma occurs and these neurologic symptoms appear, it’s important to seek medical evaluation promptly and monitor for any worsening signs such as confusion, weakness, seizures, or loss of consciousness.
