Question

Order: D5LR 1250 mL IV over 8 hours.

What is the infusion rate in mL/h?

Answer 1

The infusion rate for a D5LR 1250 mL IV over 8 hours is 156.25 mL/h. This is calculated by dividing the total volume by the number of hours of administration.

Step-by-step explanation:

The student has asked to calculate the infusion rate in mL/h for a prescribed order of D5LR to be administered over 8 hours. To find the infusion rate, you need to divide the total volume of the IV solution by the number of hours over which it is to be administered. The formula to use is:

Infusion Rate (mL/h) = Total Volume (mL) / Time (hours)

Applying this to the given order:

Infusion Rate (mL/h) = 1250 mL / 8 hours = 156.25 mL/h

This calculation indicates that the IV should be set to deliver 156.25 mL of fluid per hour to complete the infusion over the 8-hour period as prescribed.
