While providing discharge education to an older adult recently diagnosed with shingles, the nurse compares the condition to chickenpox for clarification. Which statement by the nurse best explains the clinical difference in presentation between chickenpox and shingles?

A. States the opposite of the truth (says shingles = new infection and chickenpox = reactivation); this reverses the etiologic relationship between varicella and zoster. B. Both conditions do not typically present as unilateral dermatomal lesions - shingles usually does and chickenpox is widespread; scarring is not the key distinguishing point. C. Chickenpox (primary varicella) usually causes a widespread vesicular rash across the body, while shingles (herpes zoster) is reactivation of VZV presenting as a painful, blistering rash confined to a single dermatome or band on one side of the body - this accurately describes the clinical difference. D. Shingles typically affects older or immunocompromised people who have had prior varicella, not usually younger people who haven’t had chickenpox.
