The nurse should take action C) Explain the postictal state that usually follows seizures.
The patient's seizure and subsequent lethargy and confusion indicate that he has experienced a tonic-clonic seizure. It is important for the nurse to notify the emergency response team of the seizure and provide them with all the necessary information. However, explaining the postictal state to the patient's wife is also essential to help her understand the changes in her husband's behavior and assure her that it is a normal part of the seizure episode.
During the postictal state, which occurs after a seizure, the patient may experience confusion, drowsiness, and disorientation. These symptoms can last for minutes to hours, and it is important for the nurse to support the patient and his family during this time.
