The provider orders an IV infusion of D5W 1000 ml to infuse over the next 6 hours. How many ml per hour would the IV pump be set to?

Explanation:
Calculating the infusion rate means dividing the total volume by the time over which it should be delivered. Here, 1000 mL over 6 hours equals 1000 ÷ 6 = 166.666… mL per hour. In practice, you set the IV pump to about 167 mL/hour (or 166.7 mL/hour if the pump allows decimals). Why this is the best setting: it delivers the full 1000 mL evenly over the 6-hour period, matching the order. If you used 100 mL/hour, the infusion would take 10 hours to deliver 1000 mL. At 150 mL/hour, it would take about 6.67 hours to deliver 1000 mL (not exactly 6 hours). At 200 mL/hour, it would finish in 5 hours.
