When caring for a child on steroid therapy, it is important to seek immediate medical attention if the child:

A. Skips a meal: Skipping a meal is not dangerous in itself, though it may cause temporary discomfort. B. Develops a fever: Steroids suppress the immune system; fever may indicate a serious infection, requiring prompt medical evaluation. C. Loses her hair: Hair loss may occur, but it is not an emergency. D. Vomits: Vomiting is a concern if persistent but is not the most urgent issue compared to fever in an immunosuppressed child.
