A nurse is caring for a client who is in bed and begins experiencing a tonic-clonic seizure. Which of the following actions should the nurse take?

A. Measure the duration of the seizure. Monitoring the duration of a seizure is critical in determining whether it is self-limiting or prolonged. Seizures lasting longer than five minutes may indicate status epilepticus, requiring emergency intervention. Documenting the start and end times helps guide appropriate medical management. B. Restrain the client's arms and legs to prevent injury. Restraining a client during a seizure can cause musculoskeletal injury or increase agitation. Instead, the nurse should ensure the client is in a safe position, remove nearby hazards, and allow the seizure to run its course while protecting the head. C. Insert an oral airway into the client's mouth. Forcing an airway device or object into a seizing client's mouth can cause oral trauma, aspiration, or obstruction. The priority is to maintain a patent airway by positioning the client on their side to allow secretions to drain and prevent aspiration. D. Lower the side rails of the bed when the seizure begins. Lowering the side rails increases the risk of the client falling out of bed during convulsions. If the client is already in bed, keeping the side rails up and padded can help prevent injury while allowing safe observation of the seizure activity.
