Explanation: Psoriasis is characterized by the presence of itchy, raised, red patches on the skin with silvery scales. These patches are known as plaques and are a hallmark feature of psoriasis.

c. Small, fluid-filled blisters on the palms and soles: This description is more characteristic of a condition called palmoplantar pustulosis, not psoriasis.
d. Thickened, hardened skin with deep cracks: This description is more typical of a condition called lichenified eczema or chronic contact dermatitis, not psoriasis.

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.
