A preschool-aged child who is being treated for Streptococcal pharyngitis returns to the clinic for signs of scarlet fever. Which assessment finding provides the earliest indication to the nurse that the child is experiencing a reaction to the toxins that are created by the Streptococcus bacteria?

A. Flaky, peeling skin (desquamation) occurs in later stages of scarlet fever, typically after the rash begins to fade. It is not an early sign of the disease. B. A red, sandpaper-like rash that typically begins on the chest and spreads outward is one of the earliest indications of scarlet fever. This rash is caused by exotoxins produced by Streptococcus pyogenes and is a hallmark sign of the illness. C. A white coating on the tongue, often followed by a characteristic “strawberry tongue,” develops later in the progression of scarlet fever rather than as an early symptom. D. While fever is a common symptom of streptococcal infections, it is not the earliest indicator of scarlet fever. The rash usually appears within 12 to 48 hours of fever onset, making it a more specific early sign.
