Answer to Question 1

B
Feedback:
Atopic dermatitis or eczema is characterized by a dry, red, scaly rash with lichenification and hypertrophy. An erythematous papulovesicular rash is associated with contact dermatitis. Pustules and vesicles with honey-colored exudates suggest nonbullous impetigo. Hypopigmented oval scaly lesions are associated with tinea versicolor.

Answer to Question 2

B
Feedback:
Urticaria is a type I hypersensitivity reaction caused by an immunologically mediated antigenantibody response of histamine release from the mast cells. Vasodilation and increased vascular permeability result, leading to erythema and then wheals. The rash is pruritic and blanches with pressure.
