The nurse is caring for a client diagnosed with psoriasis vulgaris who is receiving a psoralen and ultraviolet A light (PUVA) treatment. Which assessment finding indicates that the client has been overexposed to the treatment?

Choice A reason: The correct answer is a) because tenderness upon palpation and generalized erythema indicate overexposure to UV light, resulting in sunburn-like symptoms. Choice B reason: Brown, rough, greasy, wart-like papules on the face are not typically associated with overexposure to PUVA treatment. Choice C reason: Needing sunglasses because sunlight hurts the eyes may indicate photosensitivity but is not the primary sign of overexposure. Choice D reason: Thick skin plaques topped by silvery white scales are characteristic of psoriasis, not a sign of overexposure to PUVA treatment.
