A nurse is preparing to administer dextrose 5% in water IV to infuse at 100 mL/60 min.
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. (Round to the nearest whole number.).

Full Explanation
The nurse should set the IV flow rate to deliver 100 gtt/min.
To calculate the flow rate in gtt/min, you can use the formula: (Volume to be infused (mL) x Drop factor (gtt/mL)) ÷ Time (min) = Flow rate (gtt/min).
Plugging in the values from the question: (100 mL x 60 gtt/mL) ÷ 60 min = 100 gtt/min.
