List red flags in a concussion assessment that require immediate removal from play.

• A. Loss of consciousness, amnesia, and confusion persisting.
• B. Loss of consciousness, amnesia, confusion persisting, persistent vomiting, worsening headache, seizure, slurred speech, focal deficits, deterioration with exertion.
• C. Only headache with dizziness.
• D. No symptoms.

Answer: (B)

Red flags in concussion assessment signal potential serious brain injury and require immediate removal from play and urgent medical evaluation. The most complete set of red flags includes loss of consciousness, amnesia, and confusion that persists, plus persistent vomiting, a worsening headache, seizure, slurred speech, focal neurological deficits, or deterioration with exertion. These signs point to evolving intracranial injury or other acute brain issues, so stopping play right away and seeking medical care is essential. Other options miss some of these critical signs or describe symptoms that are common and not emergencies by themselves, or describe no symptoms at all, which is not sufficient for urgent action.
