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.)
To find the infusion rate in mL/hour, we need to convert the prescribed dose in milliunits/min to units/hour and then use the concentration of oxytocin in the IV bag to find the corresponding volume in mL/hour. To convert milliunits/min to units/hour, we multiply by 60. In this case, 2 milliunits/min is equivalent to 2 x 60 = 120 units/hour. To find the volume in mL/hour, we divide the dose in units/hour by the concentration of oxytocin in units/L and multiply by 1000. In this case, the concentration of oxytocin is 20 units/L, so the volume in mL/hour is (120 / 20) x 1000 = 6000 mL/hour.
