A nurse is planning to reinforce teaching about head injuries with a group of parents of school-age children. The nurse should instruct the parents to monitor for and report which of the following manifestations?

Rationale:A) Insomnia is a sleep disorder and is not typically associated with head injuries unless there is a concurrent neurological complication.B) Irritability can be a sign of increased intracranial pressure following a head injury and should be promptly reported for further evaluation.C) Diarrhea is not a common manifestation of head injuries and would not typically be included in monitoring and reporting instructions.D) Hypothermia is not typically associated with head injuries unless there is a severe injury with shock, and it is not a common manifestation requiring monitoring in the acute phase of head injury.
