The nurse notes that the patient has been diagnosed with arterial insufficiency. The patient has a dark-skinned complexion. Which assessment finding would support this diagnosis?

A. Orange-yellow tinge on soles of feet: This clinical finding is typically associated with carotenemia, resulting from excessive dietary intake of vitamin A precursors. It is a benign metabolic state and does not indicate peripheral vascular compromise. It involves pigment deposition rather than an alteration in arterial perfusion. B. Vitiligo: This is a chronic autoimmune condition characterized by the localized or generalized loss of melanocytes, resulting in depigmented white patches. It is an integumentary disorder unrelated to the circulatory system or arterial flow. It does not provide information regarding the oxygenation of peripheral tissues. C. Warm to palpation: Skin that is warm to the touch suggests adequate arterial inflow and venous return or localized inflammation. Arterial insufficiency typically presents with poikilothermia, where the affected limb feels cool or cold due to diminished blood supply. Warmth is a contradictory finding for a diagnosis of ischemia. D. Ashen gray skin: In dark-skinned individuals, pallor resulting from reduced arterial blood flow manifests as an ashen or gray appearance of the skin. This occurs because the underlying red-pink tones of oxygenated hemoglobin are absent. It is a critical indicator of severe peripheral tissue hypoxia and ischemia.
