The nurse is caring for a patient with psoriasis and notices the presence of "Auspitz sign" during the assessment. What does this finding indicate?

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: The primary assessment technique used to diagnose psoriasis is a physical examination of the skin. The characteristic red, raised patches with silver scales are indicative of psoriasis. While additional tests like skin biopsy may be used to confirm the diagnosis, the initial diagnosis is based on the visual appearance of the skin lesions.

Incorrect choices: a. A skin biopsy may be performed to confirm the diagnosis of psoriasis, but it is not the primary assessment technique used to diagnose the condition.

b. Blood tests may be conducted to rule out other conditions or assess for systemic involvement, but they are not the primary method of diagnosing psoriasis.

d. MRI is not a diagnostic tool for psoriasis. It may be used in certain cases to assess joint involvement in psoriatic arthritis, but it does not diagnose psoriasis itself.
