A nurse is collecting data from a client who has herpes zoster (shingles). Which of the following is an expected finding?

A. Blisters at the corners of the mouth are characteristic of herpes simplex virus type 1 (HSV-1), which primarily causes oral lesions or cold sores. HSV-1 is not responsible for shingles, which arises from reactivation of the varicella-zoster virus (VZV). B. Fluid-filled vesicles in the genital area are typical of herpes simplex virus type 2 (HSV-2) infections, which cause genital herpes. These lesions do not follow dermatomal patterns, unlike shingles, and are not related to VZV reactivation. C. Herpes zoster (shingles) results from the reactivation of latent varicella-zoster virus (VZV) in dorsal root ganglia. It presents as painful, clustered vesicles along a single dermatome or nerve pathway, often unilateral. Pain, itching, and burning usually precede the appearance of the vesicles (prodromal phase). D. Pustules scattered over the ribcage suggest generalized infection or primary varicella (chickenpox). Shingles lesions are localized to a single dermatome and do not appear in a generalized pattern across multiple dermatomes.
