A father brings his preschool aged child to the clinic because of a sore throat for the past two days and currently has a temperature of 103° F (39.4°C). The child is pale around the mouth and has flushed cheeks. The nurse processes a positive rapid strep test as prescribed. Which information should the nurse provide to the child's parent? Select all that apply.

A. Contagious until symptoms subside: Streptococcal pharyngitis is contagious until 24 hours after starting antibiotics, not until all symptoms are gone. This is important for limiting transmission to others in the household or school setting. B. Sandpaper-like rash: A sandpaper-textured rash is a hallmark sign of scarlet fever, which is a complication of strep throat. It usually begins on the neck or chest and spreads, often feeling coarse to the touch. C. Peeling and flaking skin in a week: Desquamation, or skin peeling, is common several days after a strep rash subsides, particularly on the hands and feet. This symptom signals the healing phase of scarlet fever. D. Darkening of skin under arms: Darkened underarm skin is typically linked to acanthosis nigricans, associated with insulin resistance or obesity. It is not seen with streptococcal infections or fever-related conditions. E. Fever lasting for 7 to 10 days: Fever from strep throat usually resolves quickly within 24–48 hours of initiating antibiotic therapy. Prolonged fever would be atypical and requires further evaluation for complications.
