HOSA Medical Math Assessment Practice Test

To determine the hourly rate of infusion, the total volume of fluid administered is divided by the total time taken for the infusion. In this scenario, the patient is receiving a total of 240 mL over a period of 4 hours.

Using the formula for calculating the rate of infusion:

Hourly rate = Total volume (mL) ÷ Total time (hours)

Here, substituting in the provided values:

Hourly rate = 240 mL ÷ 4 hours = 60 mL/hour.

This calculation shows that the patient is receiving 60 mL of fluid for each hour of the infusion. The result accurately reflects the pace at which the IV fluid is delivered to the patient, which is crucial for maintaining proper hydration and medication delivery. This understanding of calculating infusion rates is essential in patient care to ensure dosages are administered correctly over time.
