Which is NOT indicated in the initial management of typical viral croup?

• A. Antibiotics
• B. Nebulized racemic epinephrine
• C. Humidified air or cool mist
• D. Maintaining airway and oxygenation

Answer: (A)

Viral croup is a viral illness that causes subglottic swelling, so the focus of initial care is to keep the airway open and support breathing. Treatments that help reduce airway edema, such as a corticosteroid (like dexamethasone) and, if the symptoms are moderate to severe, nebulized racemic epinephrine, are appropriate. Humidified air or cool mist is a traditional supportive measure, though the evidence for its effectiveness is variable. Antibiotics are not indicated in the initial management because the illness is viral, and antibiotics do not shorten the course or improve outcomes unless there is a suspected or confirmed bacterial co-infection or another bacterial airway condition.
