Which of the following should the nurse emphasize to the patient about avoiding triggers for psoriasis flare-ups?

Explanation: Topical retinoids can increase the skin's sensitivity to sunlight and may cause sunburn. Patients should avoid excessive sun exposure and use sunscreen to protect their skin when using topical retinoids.

Incorrect choices: a. Topical retinoids should be applied to dry skin, not wet skin, to ensure proper absorption and effectiveness.

b. Topical retinoids are typically applied to the entire affected area, not just individual psoriasis plaques. They work best when applied consistently to the entire affected area.

c. Topical retinoids may take several weeks to show significant improvement in psoriasis symptoms, and immediate relief is not typical.

Explanation: Stress is a known trigger for psoriasis flare-ups. Managing stress through relaxation techniques, such as meditation or deep breathing, can help reduce the risk of exacerbations.

Incorrect choices: a. "Maintain a healthy diet, including foods high in sugar and saturated fats." - While a healthy diet is beneficial for overall health, there is no specific evidence that links certain foods to psoriasis flare-ups.

c. "Exposure to cold weather can help improve psoriasis symptoms." - Cold weather may actually exacerbate psoriasis symptoms, as dry and cold conditions can lead to skin dryness and irritation.

d. "Regularly use alcohol-based hand sanitizers to prevent infections." - Alcohol-based hand sanitizers can dry out the skin and may irritate psoriasis lesions. It is better to use gentle, non-irritating handwashing techniques.
