The nurse is assessing a patient with suspected psoriasis. What is the primary assessment technique used to diagnose psoriasis?

A.

Skin biopsy.

B.

Blood test.

C.

Physical examination.

D.

Magnetic resonance imaging (MRI).

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

Explanation: Psoriasis commonly presents as red, scaly, and thickened patches on the skin. These patches can be itchy, painful, and sometimes crack and bleed.

Incorrect choices: a. Smooth and pink patches on the skin - This is not characteristic of psoriasis, which typically involves scaling and thickening of the skin.

b. Flaky, white patches on the skin - This is not typical of psoriasis; the patches are usually red and scaly.

d. Raised, flesh-colored bumps on the skin - This description does not match the typical appearance of psoriasis patches.

Correct Answer is C

Explanation

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.
