The healthcare provider prescribes a continuous infusion of labetalol at 2 mg/minute. Labetalol HCI Injection USP 200 mg in 200 mL of 5% Dextrose Injection, USP, is delivered to the unit. This means that for every mL of the solution, there is 1 mg of labetalol (200 mg / 200 mL = 1 mg/mL). To administer a dose of 2 mg/minute, the nurse should program the infusion pump to deliver 120 mL/hour (2 mg/minute × 60 minutes/hour = 120 mg/hour; 120 mg/hour ÷ 1 mg/mL = 120 mL/hour).
