The order from a provider is: Start a heparin drip at 1200 units per hour The pharmacy provides you a 250 mL NS with 25,000 units of heparin. What will be the rate on the infusion pump?

Answer and Explanation

The Correct Answer is ["12"]

To calculate the rate for the infusion pump, you need to determine how many milliliters per hour (mL/hr) will deliver 1200 units of heparin. First, find the concentration of the heparin solution by dividing the total units of heparin by the total volume of the solution. In this case, 25,000 units divided by 250 mL equals 100 units/mL. Next, divide the ordered amount of heparin units per hour by the concentration to find the rate in mL/hr. So, 1200 units per hour divided by 100 units/mL equals 12 mL/hr.

Correct Answer is ["21"]

Explanation

Total volume to be infused: 1.5 liters (as given in the order)

1 liter = 1000 mL

Total volume (mL) = 1.5 liters x 1000 mL/liter = 1500 mL

Infusion time: The solution needs to be infused over 18 hours.

Total time (minutes) = Total time (hours) x Minutes/hour

Total time (minutes) = 18 hours x 60 minutes/hour = 1080 minutes

Rate (mL/min): Calculate the volume to be infused divided by the total time in minutes. Rate (mL/min) = Total volume (mL) / Total time (minutes)

Rate (mL/min) = 1500 mL / 1080 minutes = 1.39 mL/min (rounded to two decimal places)

Drip factor: The drip factor is 15 gtt/mL, meaning 15 drops deliver 1 mL of solution. Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)

Rate (gtt/min) = 1.39 mL/min x 15 gtt/mL = 20.85 gtt/min = 21 gtt/min (rounded to the nearest whole number)

Correct Answer is ["0.17"]

Explanation

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.
