An adult client exhibits an allergic reaction to an insect bite. The nurse should observe the client's skin for which finding?

A. Papules are small, raised, solid lesions, but they are not the typical primary skin lesion in an allergic reaction. B. Wheals are raised, red, and itchy areas of the skin that appear in response to an allergic reaction, such as from an insect bite. Wheals are a hallmark sign of urticaria (hives) often seen in allergic reactions. C. Fissuring refers to deep cracks or breaks in the skin, typically seen in conditions like chronic dermatitis or eczema, not in acute allergic reactions. D. Excoriation involves skin damage caused by scratching and is secondary to itching, not a primary skin lesion of an allergic reaction.
