A nurse enters the room of a school-age child and finds them on the floor experiencing a tonic-colonic seizure. Which of the following actions should the nurse take?

Turn the child on to their side When a child is experiencing a tonic-clonic seizure, the priority is to ensure their safety and protect their airway. Turning the child onto their side helps to prevent aspiration and maintain an open airway by allowing any saliva or fluids to drain out of the mouth. This position also helps to minimize the risk of injury. The other options are incorrect: Restraining the child's upper extremities in (option A) is not recommended during a seizure as it can potentially cause harm to the child or others around them. Placing a padded tongue blade in the child's mouth in (option C) is an outdated practice that is no longer recommended. It can cause injury and is not necessary during a seizure. Placing a pillow under the child's head in (option D) is generally not recommended during a seizure. It can interfere with the positioning of the head and may compromise the airway. The focus should be on maintaining an open airway and preventing injury, which is achieved by turning the child onto their side.
