A patient is to receive 1000 mL IV over 8 hours. What is the IV flow rate in mL/hour?

Calculating IV flow rate involves dividing the total volume by the time over which it will be given. For 1000 mL over 8 hours, 1000 ÷ 8 equals 125. So the IV flow rate is 125 mL per hour, meaning 125 mL is delivered each hour and it will take 8 hours to reach 1000 mL. If you check the other options, 100 mL/hour would take 10 hours, 150 mL/hour would take about 6.7 hours, and 200 mL/hour would take 5 hours, so those aren’t correct for an 8-hour total.
