Correct Answer is A

Explanation

Choice A rationale
Exercise, in general, is beneficial and should not exacerbate systemic lupus erythematosus (SLE). In fact, regular, gentle exercise can improve overall health and reduce symptoms.
Choice B rationale
Infection can trigger or exacerbate SLE flares by activating the immune system, which can cause increased inflammation.
Choice C rationale
Sunlight exposure can exacerbate SLE due to photosensitivity, leading to skin rashes and triggering systemic flares.
Choice D rationale
Pregnancy can exacerbate SLE due to hormonal changes and the additional strain on the immune system.

A. Apply powder liberally to sensitive skin areas. B. Wash the hair with a strong protein shampoo. C. Use a sun-blocking agent with a sun protection factor of at least 30. D. Avoid using moisturizing lotions on the skin.

Correct Answer is C

Explanation

Choice A rationale
Applying powder to sensitive skin areas can cause dryness and irritation, exacerbating SLE symptoms. Powders can also block pores, increasing the risk of skin infections.
Choice B rationale
Using a strong protein shampoo is not relevant to managing SLE. It won't address the photosensitivity or skin issues commonly associated with SLE.
Choice C rationale
Sun protection is crucial for SLE patients due to photosensitivity. UV exposure can trigger flare-ups, making a sun-blocking agent with SPF 30 or higher essential for skin protection.
Choice D rationale
Moisturizing lotions help prevent dryness and protect the skin barrier, which is important in SLE management. Avoiding them can lead to skin complications.
