Final answer:
During the immediate postictal period, a nurse should position the child safely, monitor vital signs, provide a calm environment, comfort the child, and document the recovery progress.
Step-by-step explanation:
A nurse caring for a school-age child who has experienced a tonic-clonic seizure should take several important actions during the immediate postictal period.
These include ensuring the child is in a safe position, typically on their side to keep the airway clear and prevent aspiration, monitoring vital signs and level of consciousness, and providing a calm and quiet environment to support recovery.
Comforting the child and preparing to provide information about the seizure to healthcare providers and parents are also key actions.
It's essential to observe and document the child's recovery progress as well.
