If a client has herpes zoster, he or she has:

A client with herpes zoster is indeed experiencing shingles. This viral infection is caused by the reactivation of the varicella-zoster virus, which also causes chickenpox. Once a person has chickenpox, the virus remains dormant in the nervous system and can reactivate later in life, leading to shingles. Shingles is characterized by a painful, blistering rash often localized to a specific area of the body, typically on one side, and is usually accompanied by pain, burning, and sensitivity in the affected area.

In contrast, cold sores are caused by the herpes simplex virus, which is different from the varicella-zoster virus that causes shingles. Psoriasis is a chronic autoimmune condition characterized by red, scaly patches on the skin, resulting from accelerated skin cell production. Eczema is known as atopic dermatitis, a common inflammatory skin condition that causes itchy, red, and inflamed skin. Each of these conditions is distinct from herpes zoster and emphasizes the importance of understanding viral infections and their manifestations to provide appropriate care and treatment.
