The healthcare provider prescribes a continuous infusion of labetalol HCl at 2 mg/minute. "Labetalol HCl Injection USP 200 mg in 200 mL of 5% Dextrose Injection," is delivered to the unit. How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.)

Calculation: Calculate the desired dose per hour in milligrams: Desired dose per minute = 2 mg/minute Desired dose per hour = 2 mg/minute x 60 minutes/hour = 120 mg/hour Determine the concentration of labetalol HCl in the IV solution: Total amount of labetalol HCl = 200 mg Total volume of solution = 200 mL Concentration = Total amount / Total volume = 200 mg / 200 mL = 1 mg/mL Calculate the infusion rate in mL/hour: Infusion rate (mL/hour) = Desired dose per hour (mg/hour) / Concentration (mg/mL) = 120 mg/hour / 1 mg/mL = 120 mL/hour
