Order: 1000 mL of D5½NS with 1 ampule of multiple vitamins to infuse over 8 hours Available: Macrodrip set: 15 gtt/mL Calculate the IV flow rate in gtt/min.

Given: Volume of fluid: 1000 mL Infusion time: 8 hours Drop factor: 15 gtt/mL Formula: Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr Step 1: Calculate the infusion rate in mL/hr: Infusion rate (mL/hr) = Volume (mL) / Time (hr) Infusion rate (mL/hr) = 1000 mL / 8 hr Infusion rate (mL/hr) = 125 mL/hr Step 2: Calculate the flow rate in gtt/min: Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr Flow rate (gtt/min) = (125 mL/hr x 15 gtt/mL) / 60 min/hr Flow rate (gtt/min) = 1875 gtt/hr / 60 min/hr Flow rate (gtt/min) = 31.25 gtt/min Step 3: Round to the nearest whole number: Flow rate (gtt/min) ≈ 31 gtt/min
