The nurse observes that the lower legs of a client with diabetes mellitus are shiny and with no hair growth. To obtain additional data to support these findings, which assessment should the nurse perform?

Choice A rationale Measuring capillary glucose provides information about current blood sugar levels, which is crucial for managing diabetes. However, shiny, hairless lower legs are indicative of chronic peripheral arterial disease (PAD), a microvascular complication, and while hyperglycemia contributes to PAD, a single glucose reading doesn't directly assess arterial perfusion. Choice B rationale Shiny skin and absent hair growth on the lower legs are classic signs of peripheral arterial insufficiency, indicating reduced blood flow to the extremities. Palpating the dorsalis pedis pulses directly assesses the patency and strength of peripheral arteries, providing objective data on arterial perfusion and supporting the suspicion of compromised circulation. Normal pulses are usually palpable and regular. Choice C rationale Asking about weakness or hunger relates to symptoms of hypoglycemia or hyperglycemia, which are acute metabolic imbalances in diabetes. While important for overall diabetic management, these symptoms do not directly assess the vascular integrity or perfusion status of the lower extremities, which is indicated by the observed skin and hair changes. Choice D rationale Comparing the range of motion of both legs assesses joint mobility and musculoskeletal integrity. While diabetes can lead to musculoskeletal complications like stiff joints, this assessment does not directly address the vascular changes (shiny skin, hair loss) that are indicative of impaired arterial blood flow to the lower limbs.
