A nurse is administering 0.9% sodium chloride 1,000mL IV over 8 hours. What should be the infusion rate in mL/hr?

To calculate the infusion rate, you need to determine how many milliliters of the IV fluid will be administered per hour. The total volume to be infused is 1,000 mL, and the total time for the infusion is 8 hours.

To find the infusion rate in mL/hr, you can use the formula:

Infusion rate (mL/hr) = Total volume (mL) / Total time (hr)

Substituting the values:

Infusion rate = 1,000 mL / 8 hr = 125 mL/hr

This means that to administer a total of 1,000 mL over the 8-hour period, the nurse should infuse the fluid at a rate of 125 mL per hour. This rate ensures that the entire volume will be delivered within the allotted time frame, which is critical for maintaining the correct fluid balance and therapeutic levels for the patient.
