If a school-age child has epiglottitis, what is the most appropriate nursing action?

Monitoring the child's oxygen saturation is the most appropriate nursing action when managing a school-age child with epiglottitis. This condition is characterized by inflammation of the epiglottis, which can lead to airway obstruction and respiratory distress. Maintaining adequate oxygenation is critical, as compromised airway management can result in hypoxia.

By closely monitoring the child's oxygen saturation, the nurse can quickly identify any deterioration in respiratory status. If the saturation drops, it would indicate that the child may be experiencing an airway obstruction or insufficient oxygen exchange, necessitating immediate intervention. Continuous assessment allows for prompt responses to potential life-threatening complications.

In contrast, obtaining a throat culture may be misplaced as it could provoke airway spasms or distress in a patient who is already experiencing significant swelling in the throat area. While supplemental oxygen and humidified air may be beneficial in some circumstances, monitoring oxygen saturation directly addresses the immediate concern for the child's safety and stability. Additionally, placing the child in a supine position could further compromise airflow, making it a less suitable choice.
