A male client with a brain tumor is scheduled for a biopsy in the morning. During the admission procedure, the client has a tonic-clonic seizure that lasts 50 seconds. Following the seizure, the client is lethargic and confused, and his wife tells the nurse that her husband has never had a seizure before and has always been alert and communicative. Which action should the nurse take?

A. Notify the emergency response team of the client's seizure: While the seizure is significant, it lasted less than 1 minute and resolved spontaneously. There is no need to call an emergency response team unless complications arise or the seizure becomes prolonged. B. Keep orienting the client to time and space until he is less confused: While supportive, this is not the priority. Postictal confusion is expected and does not usually require active reorientation until the client regains baseline status. C. Explain the postictal state that usually follows seizures: Providing reassurance and education to the spouse about postictal symptoms (such as confusion, lethargy, and altered responsiveness) is appropriate and therapeutic. It addresses her concern while monitoring the client for further changes. D. Ask the wife to wait outside the room until the nurse can talk with her: This action excludes the spouse unnecessarily and delays communication. Involving the family promotes trust and understanding.
