When caring for a child having a seizure, which action should the nurse take first?

In the scenario of caring for a child experiencing a seizure, the most critical initial action for the nurse is to assess the client's airway patency. During a seizure, maintaining an open airway is paramount because the child may be unable to breathe adequately due to loss of consciousness and muscle control. Seizures can lead to aspiration or obstructed airflow, which can result in severe hypoxia or potential brain injury. Therefore, ensuring that the airway is clear and that the child can breathe is the nurse’s first priority.

Once airway patency is confirmed, other measures can be taken, such as administering oxygen if needed or providing safety measures. However, assessing the airway comes first in an emergency setting because it directly impacts the child's ability to oxygenate and maintain vital functions.
