A nurse in a provider's office is collecting data from a client who reports pruritus and reddened, with papules and vesicles that developed on the abdomen after changing laundry detergents. The nurse should suspect which disorder?

A. Contact dermatitis: Contact dermatitis is an inflammatory skin reaction caused by direct exposure to an irritant or allergen. The presentation includes pruritus, erythema, and the formation of papules or vesicles at the site of contact. The recent change in laundry detergent likely introduced a chemical irritant or allergen, triggering a localized hypersensitivity reaction. B. Cellulitis: Cellulitis is a bacterial infection of the dermis and subcutaneous tissue, usually caused by Streptococcus or Staphylococcus species. It presents with erythema, warmth, swelling, and tenderness, often accompanied by systemic symptoms such as fever. Vesicles are not a typical feature, and the localized exposure history makes cellulitis less likely. C. Folliculitis: Folliculitis is inflammation of hair follicles, often due to bacterial infection, irritation, or occlusion. It presents as small pustules or papules centered on hair follicles and typically occurs in areas with hair growth. Diffuse pruritus and vesicles associated with detergent exposure are not consistent with folliculitis. D. Seborrheic dermatitis: Seborrheic dermatitis is a chronic inflammatory condition affecting areas rich in sebaceous glands, such as the scalp, face, and upper trunk. It presents with erythematous patches and greasy, yellowish scales. The sudden onset after detergent exposure points away from seborrheic dermatitis.
