A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL/V to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)

Given: Volume of fluid: 100 mL Infusion time: 4 hours Drop factor: 60 gtt/mL Formula: Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr Step 1: Calculate the infusion rate in mL/hr: Infusion rate (mL/hr) = Volume (mL) / Time (hr) Infusion rate (mL/hr) = 100 mL / 4 hr Infusion rate (mL/hr) = 25 mL/hr Step 2: Calculate the flow rate in gtt/min: Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr Flow rate (gtt/min) = (25 mL/hr x 60 gtt/mL) / 60 min/hr Flow rate (gtt/min) = 1500 gtt/hr / 60 min/hr Flow rate (gtt/min) = 25 gtt/min
