 Patient study subjects will each be assigned to a clinic room and study subjects will rotate through each of the 14 rooms over the course of the half-day session. Each interaction will last 5 minutes and will consist of a focused physical examination of the patient. All 40 medicine residents will perform a routine physical exam on each patient and will document their findings. The 20 residents in the intervention group will also perform an exam on the same patients using a pocket-sized ultrasound and will document their findings.
