The pharmacy sends a bag of 150 mLs of D5W/0.456 normal saline with 25 units of Regular Insulin.
The patient is ordered to receive an insulin drip at a rate of 9 units/hour.
What rate will you set the IV pump to deliver? Numeric values only.
The Correct Answer is ["20"]
-
Calculate the total units of insulin in the IV bag:
- The bag contains 150 mL of solution.
- The concentration is 0.456 units/mL.
- Total insulin = 150 mL × 0.456 units/mL = 68.4 units.
-
Determine how long the IV bag will last:
- The ordered rate is 9 units/hour.
- Total duration = 68.4 units ÷ 9 units/hour = 7.6 hours.
-
Calculate the IV pump rate:
- The total volume of the bag is 150 mL.
- Pump rate = 150 mL ÷ 7.6 hours = 19.74 mL/hr.
- Rounded to the nearest whole number: 20 mL/hr.
So the nurse should set the IV pump to 20 mL/hr.
