The physician orders Ampicillin 2 g in 250 mL of NS IVPB to infuse over 30 minutes. Tubing drop factor is 20 gtt/mL. Calculate the flow rate in drops per minute. (Round to the nearest whole number)

Use the formula to calculate flow rate in drops per minute: Flow rate (gtt/min) = (Volume to be infused × Drop factor) ÷ Time (in minutes) Substitute the values: Flow rate = (250 mL × 20 gtt/mL) ÷ 30 min Flow rate = 5000 ÷ 30 Flow rate ≈ 166.67 Round to the nearest whole number: 167 gtt/min Final Answer: 167 gtt/min
