Incorrect choices: a. Pitting and ridging of the nails: Pitting and ridging of the nails are common nail changes seen in psoriasis and can aid in its diagnosis.

b. Koebner phenomenon upon skin trauma: The Koebner phenomenon, where new psoriatic lesions form at sites of skin trauma or injury, is a characteristic feature of psoriasis.

d. Silvery-white scales on erythematous plaques: Silvery-white scales on erythematous (red) plaques are a classic feature of psoriasis and help differentiate it from other skin conditions.

Correct Answer is C

Explanation

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.
