Choice A rationale:

Administering antibiotics intravenously as prescribed is a crucial intervention in the management of epiglottitis.

Epiglottitis is commonly caused by bacterial infections, and intravenous antibiotics are essential to target the underlying infection and prevent its spread.

The choice of antibiotic should be based on the specific causative organism and local antibiotic resistance patterns.

Choice B rationale:

Administering corticosteroids intravenously as prescribed is another important intervention in the supportive care of epiglottitis.

Corticosteroids help reduce airway inflammation, which is a significant concern in epiglottitis.

By decreasing inflammation, corticosteroids can alleviate respiratory distress and improve the patient's breathing.

Choice C rationale:

Providing hydration and nutrition by intravenous fluids is necessary in the management of epiglottitis, especially if the child is having difficulty swallowing or breathing.

Intravenous fluids ensure that the child receives adequate hydration and nutrition while minimizing the risk of aspiration, which can worsen the airway obstruction.

Choice E rationale:

Providing humidified air or cool mist therapy to moisten the airway is a supportive measure that can help ease breathing difficulties in children with epiglottitis.

Humidified air or cool mist therapy can soothe the inflamed airway, making it easier for the child to breathe.

It is essential to maintain a moist environment to prevent further irritation and discomfort.

Choice D rationale:

Educating the child and family about the prevention of epiglottitis is important for overall health awareness, but it is not a direct supportive intervention for a child already diagnosed with the condition.

While prevention strategies, such as timely vaccinations and good hygiene, are crucial, they do not constitute immediate supportive care for a child with active epiglottitis.
