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

Explanation: Psoriasis has a strong genetic component, and individuals with a family history of the condition are more likely to develop it. Specific genetic factors are involved in the immune response and skin cell growth regulation, leading to psoriasis.

Incorrect choices: b. While exposure to certain chemicals and irritants can exacerbate psoriasis symptoms, they are not the primary factor contributing to its development.

c. Psoriasis is not caused by a bacterial infection. It is a non-infectious inflammatory skin disorder.

d. Sun exposure can affect psoriasis, but it is not the primary factor contributing to its development. In some cases, moderate sunlight exposure may even improve psoriasis symptoms.

Explanation: Fatigue and malaise are common symptoms experienced by individuals with psoriasis. The chronic inflammation and immune system dysregulation in psoriasis can lead to feelings of tiredness and general discomfort.

Incorrect choices: a. Persistent fever and chills: Fever and chills are not typical symptoms of psoriasis. They may indicate an infection or other underlying health condition.

b. Frequent nosebleeds: Nosebleeds are not directly associated with psoriasis. They may be caused by other factors such as nasal dryness or irritation.

d. Excessive thirst and frequent urination: These symptoms are not typically related to psoriasis. They may be indicative of diabetes or other medical conditions.
