Review Question - QID 109865

A 65-year-old woman presents to her family doctor to reestablish care since losing her insurance. She has not had time for regular check-ups. She exercises 3-4 times a week and consumes red meat sparingly. She drank and smoked cigarettes socially with coworkers but never at home or on vacation. She wakes up with achy wrists and elbows that she suspects is from years of using a computer keyboard. She completed menopause at age 52. Her family history is notable for coronary artery disease on her father's side and colon cancer on her mother's side. She last had a colonoscopy 5 years ago that revealed no abnormal findings. Her temperature is 99°F (37.2°C), blood pressure is 125/83 mmHg, pulse is 82/min, respirations are 12/min, and oxygen saturation is 99% on room air. Her physical exam is grossly unremarkable. What diagnostic test should this patient receive?
