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. Placing a folded blanket or any soft object under the child's head helps to protect the head from injury during the seizure. Ensuring safety is a priority during a seizure. B. Putting a tongue blade or any object between the child's teeth can cause injury to the child. It is no longer recommended to place anything in the mouth during a seizure. C. Magnesium sulfate is not indicated for treating tonic-clonic seizures. The focus should be on maintaining safety and monitoring the seizure. D. Preventing movement of the child's extremities can cause injury. Instead, the nurse should protect the child from harm and ensure the environment is safe.
