A nurse is preparing to infuse dextrose 5% in 0.45% sodium chloride 500 mL IV bolus over 4 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Total volume to be infused = 500 mL. Infusion time in minutes = 4 hr × 60 min/hr = 240 minutes. Drop factor of the manual IV tubing = 60 gtt/mL. Calculate the flow rate in drops per minute (gtt/min). Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min) = (500 mL × 60 gtt/mL) / 240 min = 30000 / 240 gtt/min = 125 gtt/min. Answer: 125 gtt/min
