A provider prescribes dextrose 5% in water IV to infuse at 100 mL/hr. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?:

Answer: 100 gtt/min Flow rate (gtt/min) = (Total volume per hour (mL/hr) × Drop factor (gtt/mL)) / Time in minutes (min/hr) Given: Total volume per hour = 100 mL/hr Drop factor = 60 gtt/mL Time in minutes = 60 min/hr Apply the formula: Flow rate (gtt/min) = (100 mL/hr × 60 gtt/mL) / 60 min/hr = 6000 gtt/hr / 60 min/hr = 100 gtt/min
