He has never had an episode like this before. He denies loss of consciousness or fall. He has a history of diabetes, hypothyroidism, and peripheral arterial disease. His medications consist of metformin and levothyroxine. The patient's temperature is 98.6°F (37.0°C), blood pressure is 140/70 mmHg, pulse is 72/min, and respirations are 16/min.
