What flow rate should a pharmacy technician use to administer a 1 L bag of 0.9% sodium chloride over 8 hours?

To determine the appropriate flow rate for administering a 1 L bag of 0.9% sodium chloride over 8 hours, it's essential to calculate the flow rate based on the total volume to be infused and the total time of administration.

First, convert the total volume from liters to milliliters. Since 1 liter is equal to 1000 milliliters, the volume is 1000 mL.

Next, divide the total volume (1000 mL) by the administration time (8 hours) to find the flow rate in mL per hour.

1000 mL ÷ 8 hours = 125 mL/hour.

This calculation indicates that the correct flow rate to administer the 1 L bag over the specified duration is indeed 125 mL/hr. Thus, the answer is validated.
