Which statement identifies a red flag indicating possible intracranial injury after concussion?

• A. Changing level of consciousness
• B. Clear nasal discharge with no symptoms
• C. No headaches
• D. Normal sleep pattern

Answer: (A)

Changes in level of consciousness after a concussion indicate possible intracranial injury because they reflect a disruption in brain function from bleeding, swelling, or other brain damage. If someone becomes unusually drowsy, confused, slow to wake, or unresponsive, that change signals the need for urgent medical evaluation. Other signs like a clear nasal discharge could hint at a skull fracture with a potential CSF leak, which is serious, but it doesn’t demonstrate an immediate alteration in brain function the way a change in consciousness does. Normal sleep patterns or absence of headaches do not by themselves indicate a red flag for intracranial injury.
