B.

Contact dermatitis

C.

Nummular eczema

D.

Seborrheic dermatitis

Answer and Explanation

The Correct Answer is B

A. Atopic dermatitis is a chronic condition often associated with genetic factors, immune dysfunction, and hypersensitivity. It typically presents in individuals with a history of allergies, asthma, or hay fever.

B. Contact dermatitis occurs due to direct exposure to environmental irritants or allergens, such as soaps, detergents, chemicals, or plants like poison ivy. It can be classified into irritant contact dermatitis and allergic contact dermatitis.

C. Nummular eczema presents as coin-shaped lesions on the skin and is often associated with dry skin or allergens but is not directly linked to environmental irritants.

D. Seborrheic dermatitis affects areas rich in sebaceous glands, such as the scalp, face, and chest. It is thought to be linked to overgrowth of yeast (e.g., Malassezia) and is influenced by factors like stress and hormones.

Correct Answer is C

Explanation

Explanation: Tight-fitting clothing can cause friction and irritation to the skin, which may exacerbate eczema symptoms. It is best to opt for loose-fitting, breathable fabrics to minimize irritation.

Incorrect choices: a. "I will avoid using harsh soaps and detergents on my skin." - This statement is correct. Harsh soaps and detergents can strip the skin of natural oils and disrupt the skin barrier, leading to eczema flare-ups.

d. "I will try to identify and avoid foods that may trigger my eczema flare-ups." - This statement is correct. Identifying and avoiding trigger foods can be helpful for some individuals with eczema, as certain foods may exacerbate their condition.
