Correct Answer is A

Explanation

Explanation: Applying topical corticosteroids to affected areas can help reduce inflammation, itching, and discomfort associated with psoriasis. However, the nurse should ensure that the patient follows the prescribed dosage and instructions for the use of corticosteroids.

Incorrect choices: b. Encouraging the patient to scratch the affected areas gently is not appropriate, as scratching can exacerbate psoriasis and lead to skin damage and infection.

c. NSAIDs are not typically used to manage itching and discomfort in psoriasis. They may be prescribed for joint pain associated with psoriatic arthritis, but they do not target the skin symptoms of psoriasis.

d. While warm baths can be soothing, frequent baths may actually dry out the skin and worsen psoriasis. Additionally, the water should be lukewarm rather than hot to avoid triggering flare-ups.

Correct Answer is C

Explanation

Explanation: Psoriasis is believed to have a genetic component, and it is considered an autoimmune disorder where the immune system mistakenly attacks healthy skin cells, leading to the characteristic skin changes.

b. Exposure to environmental toxins - While environmental factors may trigger or worsen psoriasis in some individuals, they are not the primary cause of the condition.
