Question 5 of 5
The nurse is caring for a client diagnosed with psoriasis vulgaris who is receiving a psoralen and ultraviolet light (PUVA) treatment. Which assessment finding indicates that the client has been exposed to the treatment?
Correct Answer: A
Rationale: Tenderness upon palpation and generalized erythema indicate exposure to PUVA treatment for psoriasis vulgaris. PUVA combines psoralen (photosensitizing agent) with UVA light, causing skin inflammation and redness as a therapeutic effect to reduce plaques. Thick plaques are the disease itself, not a treatment sign, photosensitivity may occur but isn't specific, and wart-like papules are unrelated. Erythema and tenderness are expected post-PUVA, reflecting its mechanism of action on skin cell turnover.
