what is the total volume of D5W needed for a 24 hr period if the infusion runs at a rate of 125 ml/hr?

To determine the total volume of D5W needed for a 24-hour period when the infusion runs at a rate of 125 ml/hr, you need to multiply the infusion rate by the number of hours.

The formula to calculate the total volume is:
Total Volume = Infusion Rate (ml/hr) × Time (hr)

In this case, the infusion rate is 125 ml/hr, and the time is 24 hours.

Using the formula:
Total Volume = 125 ml/hr × 24 hr

Now, you can calculate the total volume:
Total Volume = 3000 ml

Therefore, the total volume of D5W needed for a 24-hour period with an infusion rate of 125 ml/hr is 3000 ml.
