<p>An 83-year-old man was diagnosed with type 2 diabetes mellitus 3 months ago. He has modified his diet and tries to walk at least half a mile every evening. He drinks a glass of wine with lunch and dinner daily. For the past week, he has felt dizzy upon standing and has fallen on two occasions, but has never lost consciousness. After the last episode of falling, he presented to the local emergency room (ER) where his blood pressure was 155/76 mm Hg, heart rate was 74 beats/min, and respiratory rate was 16 breaths/min. A finger stick showed a random glucose level of 64 mg/ dL.&nbsp;</p>
