A 4-year-old child is being discharged from the hospital after being treated for severe croup.

(A) Initial home treatment of croup includes placing the child in an environment of high humidity to liquefy and mobilize secretions. (B) Antihistamines should be avoided because they can cause thickening of secretions. (C) Drooling is a characteristic sign of airway obstruction and the child should be taken directly to the emergency room.
