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?
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 ["250"]
Explanation
To calculate the rate for an infusion pump, you would use the formula: rate (mL/hr) = volume to be infused (mL) / time for infusion (hr). In this case, the volume to be infused is 500 mL and the time for infusion is 2 hours. Therefore, the infusion pump rate would be calculated as 500 mL divided by 2 hours, resulting in a rate of 250 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)
