A nurse is caring for a preschooler who has epiglottitis from a streptococcal infection. Which of the following actions should the nurse take?

A. Initiate airborne precautions: Epiglottitis is transmitted via droplets, so droplet precautions are sufficient, not airborne isolation. B. Apply humidified oxygen via a mask: Provides oxygenation and helps moisturize the airway, which is essential in epiglottitis while minimizing distress. C. Use a tongue depressor to observe the back of the throat: This may trigger complete airway obstruction and is contraindicated in suspected epiglottitis. D. Attempt to obtain a throat culture: Like the tongue depressor, this may provoke laryngospasm or airway blockage-throat inspection is avoided until the airway is secured.
