A car swerved to miss a deer in the road and hit a utility pole at a low rate of speed. Damage to the car is minimal, but the 82-year-old male passenger was not wearing a seat belt and hit his head on the dashboard. He presents as confused and diaphoretic. His daughter, the driver, states that he has a history of dementia, high blood pressure, and diabetes, as well as coronary artery disease. She adds that he took his insulin about 2 hours ago. Which question to the daughter would be most important at this time?
