Which term describes several different types of skin swelling, commonly known as dermatitis, causing red, swollen, and itchy skin?

• A. Warts
• B. Cold Sores
• C. Shingles
• D. Eczema

Answer: (D)

This question tests recognizing that eczema is the umbrella term for several inflammatory skin conditions, all grouped under dermatitis. Dermatitis refers to inflammation of the skin, producing red, swollen, and itchy patches. Eczema describes these various forms—atopic dermatitis, contact dermatitis, seborrheic dermatitis, and others—that share that itchy, inflamed presentation. The other options are skin conditions caused by viruses or infections rather than inflammation-driven dermatitis: warts are HPV-related growths, cold sores come from herpes simplex virus, and shingles is a reactivation of varicella-zoster presenting as a painful dermatomal rash. Because the description centers on itchy, red, swollen skin from inflammatory processes, eczema is the best fit.
