Review Question - QID 213863

A 47-year-old woman with type I diabetes presents to her primary care physician complaining of abnormal appearance and swelling of her legs. The leg swelling started 1 year ago and has been getting worse to the point that she is no longer able to fit in her shoes. She also notes that the front of her legs are a different color than they used to be. She otherwise feels well, but reports a 10 lb. weight loss in the past year, occasional palpitations, and chronic diarrhea. Her medications include daily insulin. Her family history is significant for type I diabetes in her mother and congestive heart failure in her father. Her temperature is 98.3°F (36.8°C), blood pressure is 125/60 mmHg, pulse is 104/min, and respirations are 14/min. On physical exam, her heart rhythm is irregularly irregular, and her lungs are clear to auscultation bilaterally. Her abdomen is soft and nontender. Her legs appear as shown in Figure A. What additional finding would most likely be present in this patient?
