Calculation
The healthcare provider prescribes an IV solution of clindamycin 850 mg in 75 mL of D5W to infuse over 30 minutes. The drop factor is 15 gtt/mL. The nurse should regulate the IV to deliver how many gtt/minute? (Enter numeric value only. If rounding is required, round to the nearest whole number)
gtt/min
Explanation & Rationale
Given: Volume of fluid: 75 mL Infusion time: 30 minutes Drop factor: 15 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) = 75 mL / 30 min Infusion rate (mL/min) = 2.5 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) = 2.5 mL/min x 15 gtt/mL Flow rate (gtt/min) = 37.5 gtt/min Step 3: Round to the nearest whole number: Flow rate (gtt/min) ≈ 38 gtt/min
