Arkansas Esthetician Practice Exam

Hives are a red, itchy skin rash caused by an allergic reaction, so option B is the correct answer. Option A is incorrect because hives are not necessarily caused by a chemical exposure. Option C is incorrect because hives are not a reaction to a physical injury, rather they are a skin reaction caused by an allergen. Option D is incorrect because hives are not solely a reaction to cold temperatures, although cold urticaria (a type of hives) can occur in some individuals. It is important to remember that hives are typically an allergic reaction and can be triggered by a variety of allergens, not just physical factors.
