Marcus is a 19-year-old college student with Type 1 diabetes. He is learning carbohydrate counting to match his insulin doses. He plans to eat a meal containing 45g of carbohydrate. His insulin-to-carb ratio is 1:15, and his correction factor is 1 unit per 50 mg/dL over his target of 120 mg/dL. His pre-meal blood glucose is 220 mg/dL. How many units of rapid-acting insulin should Marcus administer before his meal?
