Correct Answer is C

Explanation

Explanation: Keeping the skin well-hydrated is essential in managing psoriasis. Patients should use fragrance-free moisturizers to prevent skin dryness and irritation, which can trigger flare-ups.

Incorrect choices: a. "Avoid using moisturizers, as they can worsen psoriasis flare-ups." - This statement is incorrect. Moisturizers are important for managing psoriasis symptoms and preventing dryness and irritation.

b. "Take hot baths with scented soaps to soothe the skin." - Hot baths and scented soaps can actually worsen psoriasis symptoms and should be avoided.

d. "Expose your skin to direct sunlight for prolonged periods to improve symptoms." - While some sunlight exposure may benefit psoriasis, prolonged and direct exposure can lead to skin damage and increase the risk of skin cancer. Sun exposure should be limited and done with caution.

Correct Answer is D

Explanation

Explanation: Taking long, hot baths can actually worsen psoriasis by drying out the skin and triggering flare-ups. Instead, patients with psoriasis should take short, lukewarm baths or showers to avoid exacerbating the condition.

Incorrect choices: a. Moisturizing the skin regularly is an essential part of psoriasis management to prevent dryness and scaling.

b. Avoiding fragranced soaps and lotions can help minimize skin irritation and sensitivity, which is beneficial for patients with psoriasis.

c. Applying sunscreen before going outside is important, as exposure to UV rays can trigger or worsen psoriasis. Sun protection helps prevent further skin damage.
