A nurse is preparing to administer 0.9% sodium chloride 100 mL IV to infuse over 15 min to a client. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual 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.)

Total volume to be infused = 100 mL. Infusion time in minutes = 15 min. Drop factor of the manual IV tubing = 10 gtt/mL. Calculate the IV flow rate in gtt/min. Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min) = (100 mL × 10 gtt/mL) / 15 min = 1000 / 15 gtt/min = 66.666... gtt/min. Round the answer to the nearest whole number. = 67 gtt/min.
