A client has been started on an anticonvulsant for a seizure disorder and asks how long he will need to take the medication. What is the nurse's best response?

"You will need to take an anticonvulsant of some type for your lifetime."

"This medication should be taken until you haven't had a seizure for a month."

"Seizures are unpredictable and so is the duration of the treatment."

"You will only need to take it for a short period of time because anticonvulsants will cure the seizure disorder."
