A client receives a prescription for oxytocin 2 milliunits/min intravenously (IV) for labor augmentation. The IV bag contains oxytocin 20 units in lactated Ringer's 1 liter. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)

Step 1: Convert the concentration to milliunits. 20 units × 1000 = 20,000 milliunits Step 2: Determine the concentration per mL. 20,000 ÷ 1000 = 20 milliunits/mL Step 3: Calculate the infusion rate. 2 milliunits/min × 60 min/hour = 120 milliunits/hour Step 4: Determine the volume to be administered. 120 ÷ 20 = 6 mL/hour
