The flow rate of the infusion is 50 gtt/min
The formula for calculating the IV(intravenous) infusion flow rate (in gtt/min) is given as total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL).
From the data provided:
Flow rate = 250 mL/100 min) * 20 gtt/min
flow rate = 50 gtt/min
Therefore, the flow rate of the infusion is 50 gtt/min
