What is the expected infusion time for 2000 mL of normal saline at a rate of 80 mL/hour?

To determine the expected infusion time for 2000 mL of normal saline at a rate of 80 mL/hour, one can use the formula for calculating time based on volume and rate. This formula is:

Infusion Time (hours) = Volume (mL) / Rate (mL/hour)

By substituting the known values into this formula:

Infusion Time = 2000 mL / 80 mL/hour

When you perform the calculation, it equals:

Infusion Time = 25 hours.

This calculation indicates that it will take 25 hours to infuse the total volume of 2000 mL when it is administered at a rate of 80 mL per hour. Therefore, the correct answer is 25 hours, affirming the rationale behind the choice made in the question. Understanding this formula and calculation is crucial for accurately planning and managing IV fluid therapy.
