What is the required flow rate to deliver 1 L over 6 hours?

• A. 150 mL/h
• B. 160 mL/h
• C. 167 mL/h
• D. 170 mL/h

Answer: (C)

Flow rate is the amount of fluid delivered per unit of time. To deliver 1 L over 6 hours, convert to milliliters and divide by time: 1000 mL ÷ 6 h = 166.666... mL/h. Since infusion rates are typically given in whole milliliters per hour, round to 167 mL/h. At this rate, you deliver about 1000 mL in 6 hours (166.7 mL/h is exact, but 167 mL/h is the practical rounding). The other options would miss the target: 150 mL/h gives 900 mL in 6 hours, 160 mL/h gives 960 mL, and 170 mL/h provides about 1020 mL in 6 hours.
