What is the total volume of IV fluid needed for an 8 hour period at a rate of 75 mL/hour?

To determine the total volume of IV fluid required over an 8-hour period at a rate of 75 mL/hour, you multiply the hourly rate by the total number of hours.

First, the calculation is performed as follows:

Total volume = rate (mL/hour) × time (hours)

In this scenario:

Total volume = 75 mL/hour × 8 hours

Total volume = 600 mL

This calculation clearly shows that for an infusion of 75 mL every hour, over the course of 8 hours, a total of 600 mL of IV fluid would be administered. Therefore, the correct interpretation of the calculations leads us to conclude that the total volume needed is indeed 600 mL.
