Question 14 :
A client receives a prescription for oxytocin 2 milliunits/min intravenously (IV) for labor augmentation. The IV bag contains oxytocin 20 units in actated Ringer's 1 liter. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)
Correct Answer: ["6 mL\/h\u00a0"]
- To calculate the infusion rate, use the formula: infusion rate (mL/h) = dose (units/h) x volume (mL) / concentration (units)
- In this case, the dose is 2 milliunits/min or 0.12 units/h
- The volume is 1000 mL and the concentration is 20 units
- Plug in the values and simplify: infusion rate = 0.12 x 1000 / 20
- The infusion rate is 6 mL/h
- The nurse should program the pump to deliver 6 mL/h
