Your patient is ordered to receive 20 units Pitocin in D5%W 500 mLs at 12 milliunits/minute.
What flow rate will you set the IV pump to deliver? Numeric values only.
The Correct Answer is ["mLs\/hr."]
Step 1 is to convert the order from milliunits/minute to units/hour. So, 12 milliunits/minute is equal to 0.72 units/hour. Step 2 is to calculate the total units in the IV bag, which is 20 units. Step 3 is to calculate the total volume of the IV bag, which is 500 mL. Step 4 is to calculate the flow rate. So, (0.72 units/hour ÷ 20 units) × 500 mL = 18 mL/hr. So, the correct flow rate to set on the IV pump is 18 mL/hr.
