The nurse is caring for a 50-year-old patient who complains of tingling in his toes. Which other assessment finding would cause the nurse to suspect arterial insufficiency?
a. Equal warmth in bilateral feet
b. Shiny, hairless legs
c. Thin, brittle toenails
d. Pedal edema
B
To distinguish arterial insufficiency, instruct the patient to dangle the feet. In arterial insuffi-ciency, feet display delayed color return, and if severe peripheral arterial disease is present, the dangling feet soon take on a dusky red color (rubor). The skin may be shiny, taunt, and hairless. Equal warmth indicates equal and sufficient blood flow to the extremities. The nails would be thick rather than thin with arterial insufficiency, and pedal edema is an indication of venous in-sufficiency.
