While in a pediatric client's room, the nurse notes that the client is beginning to have a tonic-clonic seizure. Which nursing action is priority?

Rationale: A. Dietary therapy (like ketogenic diet) is a long-term management strategy, not an immediate priority during a seizure. B. Protecting the child from injury during a tonic-clonic seizure is the priority to prevent harm. C. Administering lorazepam may be necessary but only if prescribed and seizure is prolonged; initial priority is safety. D. Referral to a neurologist is important for ongoing care but not an immediate action during the seizure.
