When administering lactated Ringer's at 1,500 mL over 10 hours, what should the IV pump settings be for mL/hr?

To determine the appropriate IV pump settings for administering 1,500 mL of lactated Ringer's over 10 hours, it's crucial to calculate the required flow rate in milliliters per hour (mL/hr).

First, convert the total volume (1,500 mL) to an hourly rate by dividing it by the total time in hours (10 hours). The calculation is as follows:

1,500 mL ÷ 10 hours = 150 mL/hr.

This means that to administer 1,500 mL over a period of 10 hours, the IV pump must be set to deliver 150 mL each hour. Thus, the correct answer is determined logically through accurate calculations, allowing for safe and efficient fluid delivery to the patient.
