Someone may have a head injury if they display which of the following symptoms?

• A. Groggy and disoriented
• B. Unequal pupils
• C. Swelling of the lower limbs
• D. Both A and B

Answer: (D)

When assessing for head injury, look for signs that show the brain is involved. If someone is groggy and disoriented, that change in consciousness often follows a bump to the head. Unequal pupils point to possible brain impact or pressure affecting the nerves that control the eyes, which is another warning sign of a brain injury. Swelling of the lower limbs isn’t typically linked to head trauma and suggests other problems unrelated to a head injury. So, seeing both altered mental status and unequal pupils together best indicates a head injury.
