A client calls the clinic and states they are experiencing intense itching and brown wavy lines between their fingers. The nurse recognizes this describes which condition?

A. Lice: Lice infestation is caused by parasitic insects that live on the scalp, body, or pubic hair and feed on human blood. The most common manifestation is intense itching of the scalp or affected hair-bearing areas with visible nits attached to hair shafts. Lice do not produce burrows or wavy lines on the skin, particularly between the fingers. B. Ringworm: Ringworm, also known as tinea corporis, is a fungal infection of the skin characterized by circular, red, scaly lesions with a raised border and central clearing. The lesions typically appear ring-shaped and may be mildly itchy. This infection does not produce thin, wavy burrow-like lines in the skin or commonly occur between the fingers in that pattern. C. Scabies: Scabies is caused by the mite Sarcoptes scabiei, which burrows into the superficial layer of the skin to lay eggs. This creates thin, brown or gray wavy lines called burrows, often found in the interdigital spaces of the fingers, wrists, and other skin folds. Intense itching, particularly at night, is a hallmark symptom due to the immune response to the mites and their waste products. D. Psoriasis: Psoriasis is a chronic autoimmune inflammatory skin condition characterized by thick, erythematous plaques covered with silvery scales. The lesions commonly appear on the scalp, elbows, knees, and lower back. Although itching may occur, psoriasis does not cause burrows or wavy lines between the fingers, which are more typical of parasitic infestation.
