Which of the following strategies should the nurse recommend to a patient with psoriasis to manage itchiness and discomfort?

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.

Explanation: The primary etiological factor in psoriasis is a genetic predisposition. Psoriasis has a strong hereditary component, and individuals with a family history of the condition are at a higher risk of developing it. While environmental triggers can exacerbate psoriasis symptoms, the condition itself is primarily influenced by genetic factors.

Incorrect choices: a. Bacterial infection: Psoriasis is not caused by a bacterial infection. It is an autoimmune condition characterized by an overactive immune response, leading to inflammation and skin cell overproduction.

b. Fungal overgrowth: Fungal overgrowth is not a cause of psoriasis. Psoriasis is not related to fungal infections and has a different underlying mechanism.

d. Allergic reaction: While certain allergens may exacerbate psoriasis symptoms in some individuals, an allergic reaction is not the primary cause of psoriasis. The condition's pathophysiology is rooted in immune system dysfunction rather than allergic responses.
