Correct Answer is B

Explanation

Histamine release: Histamine release is characteristic of Type I hypersensitivity reactions (immediate hypersensitivity) rather than Type IV.

T-lymphocyte memory cells: Type IV hypersensitivity is a delayed response mediated by T-lymphocytes, not antibodies.

Immunosuppression: Immunosuppression is not directly related to hypersensitivity reactions.

Antigen/antibody interaction: This is characteristic of Types I, II, and III hypersensitivity reactions, not Type IV.

Correct Answer is A

Explanation

A. "Minimize exposure to the sun and artificial ultraviolet light": UV light can trigger lupus flares, so sun protection is crucial.
B. "Avoid using moisturizing lotions on your skin.": Moisturizing lotions help prevent skin dryness, which is common in lupus patients.
C. "Use a sun-blocking agent with a sun protection factor of 10.": An SPF of 10 is too low for effective protection. A minimum of SPF 30 is recommended.
D. "Apply powder liberally to sensitive areas of skin.": Powders can irritate the skin and cause dryness, exacerbating skin issues in lupus.
