Order: Zosyn 1.3g in 100mL. D5W IVPB q8h to infuse over 30 min. Drop factor: 60 gtt/mL. Determine rate in gtt/min.

Given: Volume of fluid: 100 mL Infusion time: 30 minutes Drop factor: 60 gtt/mL Formula: Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL) Step 1: Calculate the infusion rate in mL/min: Infusion rate (mL/min) = Volume (mL) / Time (min) Infusion rate (mL/min) = 100 mL / 30 min Infusion rate (mL/min) = 3.33 mL/min Step 2: Calculate the flow rate in gtt/min: Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL) Flow rate (gtt/min) = 3.33 mL/min x 60 gtt/mL Flow rate (gtt/min) = 200 gtt/min
