The order from a provider is: Start Pitocin at 5 milliunits/min to induce labor. The pharmacy provides you with a 500 mL bag with 15 units of Pitocin added. What is the rate that would be set on the infusion pump?
The Correct Answer is ["0.17"]
To calculate the infusion pump rate for Pitocin, you need to determine the concentration of Pitocin in the IV bag and then set the pump to deliver the desired dose rate. The pharmacy has added 15 units of Pitocin to a 500 mL bag. To start at 5 milliunits/min, you first convert the units of Pitocin to milliunits (15 units = 15,000 milliunits). Then, divide the total milliunits in the bag by the volume of the bag to find the concentration per mL (15,000 milliunits / 500 mL = 30 milliunits/mL). Now, to find the rate at which the pump should be set to deliver 5 milliunits/min, divide the desired dose rate by the concentration (5 milliunits/min / 30 milliunits/mL = 0.1667 mL/min). Therefore, the infusion pump should be set to approximately 0.17 mL/min.

Correct Answer is ["200"]
Explanation
To calculate the rate for an infusion pump, one can use the formula: rate (mL/hr) = volume to be infused (mL) / time for infusion (hr). In this case, the volume to be infused is 100 mL and the time for infusion is 0.5 hours (30 minutes). Therefore, the rate would be 100 mL divided by 0.5 hours, resulting in an infusion rate of 200 mL/hr.
Correct Answer is ["56"]
Explanation
To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL x Drip factor) / Time in minutes. In this case, the nurse has 500 mL of Ringer's lactate to infuse over 3 hours. First, convert the hours into minutes: 3 hours x 60 minutes/hour = 180 minutes. Next, multiply the volume by the drip factor: 500 mL x 20 gtt/mL = 10,000 gtt. Finally, divide by the total time in minutes: 10,000 gtt / 180 minutes = approximately 55.56 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver around 56 gtt/min.
