During patient education on psoriasis, the nurse should emphasize the importance of:

Explanation: Psoriasis is characterized by red and raised skin patches covered with silver or white scales. These patches are often itchy and can be found on various parts of the body, such as the scalp, elbows, knees, and lower back.

Incorrect choices: a. Clear and smooth skin without any changes is not consistent with psoriasis, which is marked by visible skin changes like red, raised patches.

c. Skin rash with fluid-filled blisters may indicate conditions such as contact dermatitis or eczema but is not typical of psoriasis.

d. Purple or red lumps under the skin are more suggestive of other conditions, such as nodules or hematomas, rather than psoriasis.

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.
