What are common signs of a concussion or head injury?

• A. Vomiting and head pain only
• B. Loss of consciousness only
• C. Dizziness and nausea
• D. Confusion, headache, dizziness, vomiting, or loss of consciousness

Answer: (D)

Concussion signs come in a range, not just one symptom. Because a head injury can affect thinking, balance, and awareness in different ways, the best answer includes several common signs at once: confusion, headache, dizziness, vomiting, or loss of consciousness. That combination captures how a concussion may present—some people feel foggy or disoriented, have a headache and dizziness, may vomit, or briefly lose consciousness, and some may have only a subset of these symptoms. Importantly, losing consciousness isn’t required for a concussion to be present, and symptoms can appear immediately or develop later.

In first aid, treat head injuries with suspicion of concussion if these signs are present: monitor the person closely, keep them still and comfortable, and seek medical evaluation, especially if symptoms worsen, if there is repeated vomiting, or if there are any concerns about their ability to stay awake or respond normally. This approach helps ensure you don’t miss a concussion and reduces the risk of further harm.
