A client with chronic kidney disease (CKD) missed dialysis yesterday to attend a funeral. The client's spouse calls the home health nurse and reports that the client is lethargic and hard to arouse. Which instruction is most important for the nurse to provide?

Choice A reason: Thick skin plaques topped by silvery white scales are characteristic findings in psoriasis vulgaris itself and do not indicate overexposure to PUVA treatment. These plaques are a result of rapid skin cell turnover and are typically the target of treatment, not a side effect of overexposure.

Choice B reason: The requirement for sunglasses because sunlight hurts the eyes is not a specific indication of overexposure to PUVA treatment. While PUVA therapy can increase sensitivity to light, the use of sunglasses is a preventive measure and does not necessarily indicate overexposure.

Choice C reason: Brown, rough, greasy, wart-like papules on the face suggest the presence of seborrheic keratosis or another benign skin condition, not overexposure to PUVA treatment. These lesions are unrelated to the therapy and do not serve as an indicator of overexposure.

Choice D reason: Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. Overexposure can lead to phototoxic reactions, resulting in skin irritation, redness, and tenderness. These symptoms indicate that the client has received too much UV radiation during the treatment, leading to an adverse reaction.

Choice A reason: Rubbing painful areas gently may provide temporary relief, but it is not a specific or effective long-term management strategy for Raynaud's disease. This advice could lead to further discomfort if not done correctly, and it does not address the primary trigger, which is cold exposure.

Choice B reason: Enrolling in a pain clinic can provide pain relief alternatives, but this is a general recommendation and not specific to the management of Raynaud's disease. While pain clinics can be helpful for chronic pain management, practical daily interventions are also crucial for this condition.

Choice C reason: Wearing gloves when handling cold items is a direct and practical way to prevent painful spasms associated with Raynaud's disease. This condition is characterized by episodes of reduced blood flow to the extremities, typically triggered by cold temperatures. By wearing gloves, the client can protect their hands from cold exposure, which helps prevent these painful spasms.

Choice D reason: Return appointments for IV pain medication are not typical for managing Raynaud's disease. Pain management for Raynaud's generally focuses on preventive measures and lifestyle adjustments to avoid triggers, rather than relying on IV medications for pain relief.
