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

A. Excoriation. This indicates skin damage caused by scratching but does not specifically describe an allergic reaction. B. Fissuring. This refers to deep cracks in the skin and is not a typical feature of an allergic reaction to an insect bite. C. Wheals. This is the best choice as wheals are raised, red, itchy areas commonly associated with allergic reactions. D. Papules. Papules are small, raised, solid pimples that can occur with many skin conditions, not specifically allergic reactions
