An IV infusion is to deliver 900 mL over 9 hours. What is the infusion rate in mL/hr?

Explanation:
To determine an IV infusion rate, divide the total volume to be infused by the total time over which it should be delivered. Here, 900 mL over 9 hours gives 900 ÷ 9 = 100 mL per hour. In other words, the pump should deliver 100 mL each hour to reach 900 mL in 9 hours. Quick check: 100 mL/hr × 9 hr = 900 mL. If you tried 90 mL/hr, you’d deliver 810 mL; 110 mL/hr would yield 990 mL; 120 mL/hr would yield 1080 mL—so 100 mL/hr is the rate that matches the requirement.
