The order from a provider is: 1.5 liters of LR to infuse over 18 hours. The drip factor is 15 gtt/mL. How many gtt/min?
The Correct Answer is ["21"]
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 ["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.
