Which signs constitute red flags of concussion that require removing a child from activity?

• A. Headache with impact, confusion, dizziness, vomiting, amnesia, loss of consciousness, balance problems.
• B. Headache with no other symptoms after impact.
• C. Mild nausea after exercise with full balance.
• D. Dizziness that resolves quickly with rest.

Answer: (A)

The signs being tested are red flags for a concussion—these indicate a potential brain injury and mean the child must be removed from activity right away and evaluated by a medical professional. When a head impact is followed by a headache, confusion, dizziness, vomiting, any memory loss (amnesia), loss of consciousness, or problems with balance, these are all serious warning signs. They show that the brain may be injured and continuing to play could cause further harm, including the risk of a second concussion. The safe approach is to stop activity immediately, monitor for worsening symptoms, and seek medical assessment.

Other scenarios described—like a headache without other symptoms, mild nausea after exercise with full balance, or dizziness that goes away with rest—can occur with fatigue or overexertion and are not in themselves red flags. They don’t by themselves mandate immediate removal from activity, though they still deserve careful monitoring and medical advice if they persist or worsen.
