The order from a provider is: Start Pitocin (Oxytocin) at 5 milliunits/min to induce labor. The pharmacy provides you with a 200 mL bag with 20 units of Pitocin added. What is the rate on the infusion pump?
The Correct Answer is ["3"]
Step-by-Step Calculation
Understanding the Problem
Desired Pitocin dose: 5 milliunits/min
Pitocin concentration: 20 units in 200 mL
We need to find the infusion rate in mL/hour.
Calculations
Convert milliunits to units:
5 milliunits/min = 0.005 units/min
Calculate units per hour:
0.005 units/min X 60 min/hour = 0.3 units/hour
Calculate the concentration of Pitocin:
Pitocin concentration = Total units / Total volume
Pitocin concentration = 20 units / 200 mL = 0.1 units/mL
Calculate the infusion rate:
Infusion rate (mL/hour) = Desired Pitocin dose (units/hour) / Pitocin concentration (units/mL)
Infusion rate = 0.3 units/hour / 0.1 units/mL = 3 mL/hour
The infusion pump rate should be set to 3 mL/hour.

Explanation
The nurse should set the IV infusion to deliver 31 gtt/min.
Let's calculate the drip rate
Understanding the problem
We need to administer 3 liters (3000 mL) of DSLR over 24 hours.
The drop factor is 15 gtt/mL.
We need to find the drip rate in gtt/min.
Step-by-step calculation
Convert hours to minutes:
24 hours = 24 X 60 minutes = 1440 minutes
Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Total volume (mL) / Total time (min)
Infusion rate = 3000 mL / 1440 min = 2.0833 mL/min
Calculate the drip rate:
Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)
Drip rate = 2.0833 mL/min X 15 gtt/mL = 31.25 gtt/min
Round the drip rate to the nearest whole number:
Drip rate ≈ 31 gtt/min
The nurse should set the IV infusion to deliver 31 gtt/min.
