Which symptom indicates that the client may be at risk for seizures post-head injury?

A symptom such as confusion following a head injury can be indicative of potential neurological issues, including the risk for seizures. Confusion suggests that there may be underlying changes in the brain's function or structure, which are critical concerns after any head trauma. The brain may experience disturbances in electrical activity due to the injury, and this can lead to seizures.

Increased intracranial pressure, structural damage, or cortical irritation can all lead to confusion and, subsequently, increase the likelihood of seizure activity. Identifying confusion as a symptom can prompt early assessment and intervention, ultimately improving patient outcomes.

While severe headache can also be associated with neurological disturbances, it is often a more general symptom and does not directly indicate seizure risk. Increased appetite and a normal pulse are generally not associated with seizure risk in the context of a head injury.
