A nurse is caring for a school-age child who is experiencing a tonic-clonic seizure. Which of the following actions should the nurse take?

A. Administer magnesium sulfate IM to the child: Seizures are typically managed with anticonvulsant medications or other specific treatments, but magnesium sulfate is primarily used in other conditions, such as preeclampsia in pregnant women. B. Place a folded blanket under the child's head: Placing a folded blanket or soft material under the child's head is a safe action to prevent injury during a tonic-clonic seizure. It helps protect the head from hitting the floor or any hard surfaces during the seizure. C. Prevent movement of the child's extremities: It is not recommended to try to prevent movement of the child's extremities during a tonic-clonic seizure. Trying to restrain or hold the child down can cause injury. The goal is to ensure the child’s safety and prevent injury. D. Put a tongue blade between the child's teeth: Inserting a tongue blade between the child’s teeth is dangerous and should never be done. It could lead to injury, including broken teeth or damage to the child's mouth or throat.
