A nurse is preparing to administer vancomycin 1000 mg in 100 mL of D5W to infuse over 1.5 hours. The drop factor of the manual IV tubing is 15 gtt/ml. The nurse should adjust 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.)

Calculation: Total volume = 100 mL. Infusion time = 1.5 hours = 1.5 hours x 60 minutes/hour = 90 minutes. Drop factor = 15 gtt/mL. Calculate the infusion rate in drops per minute (gtt/min). Infusion rate (gtt/min) = (Total volume (mL) x Drop factor (gtt/mL)) / Total time (min) = (100 mL x 15 gtt/mL) / 90 min = 1500 gtt / 90 min = 16.666... gtt/min. Round to the nearest whole number. = 17 gtt/min.
