The physician orders vancomycin 500 mg in 250 mL of D5W IVPB daily to infuse over 2 hours. Tubing drop factor is 15 gtt/mL. Calculate the flow rate in drops per minute.

Flow rate (gtt/min)=Time (min)Volume (mL)​×Drop factor (gtt/mL) Given: Volume = 250 mL (vancomycin in 250 mL of D5W) Time = 2 hours = 120 minutes Dropfactor=15gtt/mLtubingdropfactor Step 1: Calculate the flow rate: rate=250 mL120 min×15 gtt/mL Flow rate=2.0833×15=31.25 gtt/min Step 2: Round to the nearest whole number: Answer: 31 drops per minute
