What is the IV fluid infusion rate in mL/h for a client prescribed 7200 mL of fluid in the first 24 hours, with 3600 mL given in the first 8 hours?

To determine the correct IV fluid infusion rate, first, it’s essential to understand the total fluid requirement and how much has already been administered. The total prescribed amount of fluid is 7200 mL for 24 hours.

After the first 8 hours, 3600 mL has been given. To find out how much fluid remains to be infused in the next 16 hours, you subtract the amount already given from the total requirement:

7200 mL (total) - 3600 mL (administered) = 3600 mL remaining.

Next, to find the infusion rate for the remaining 16 hours, divide the remaining volume by the number of hours left:

3600 mL ÷ 16 hours = 225 mL/h.

However, this figure pertains only to the remaining volume over the next 16 hours. To maintain the total infusion consistent over the 24 hours, it's helpful to consider the overall average rate necessary for the full 7200 mL.

Dividing the total volume by the total time:

7200 mL ÷ 24 hours = 300 mL/h.

This calculation specifies that the average rate of infusion should be 300 mL/h to meet the
