HESI Dosage Calculations Practice Exam

To determine the infusion rate in milliliters per hour, it's essential to convert the total volume of the IV bag from liters to milliliters, and then divide that by the total time in hours over which the infusion will occur.

1 liter is equivalent to 1,000 milliliters. Given that the IV bag contains 1 liter, you have a total of 1,000 ml to infuse.

Next, since the infusion is to be administered over a period of 12 hours, you would divide the total volume by the time:

1,000 ml ÷ 12 hours = 83.3 ml/hour.

This calculation demonstrates how to find the infusion rate by breaking down the total volume and time, leading to the conclusion that the correct infusion rate is 83.3 ml/hour. The calculation also aligns with standard practices in healthcare for determining how quickly to administer IV fluids, ensuring that patients receive the correct amount of fluids over the specified time.
