If the infusion rate is 100ml/hr, what is this rate in milliliters per minute?

To convert an infusion rate from milliliters per hour to milliliters per minute, you need to divide the hourly rate by the number of minutes in an hour. There are 60 minutes in an hour, so you would take the given rate of 100 ml/hr and divide it by 60.

The calculation would be:

100 ml/hr ÷ 60 minutes/hr = 1.67 ml/min.

This means that the correct answer, which represents the infusion rate in milliliters per minute, is 1.67 ml/min. Understanding this conversion is important for accurately administering medications and IV fluids, as many clinical situations require dosing calculations based on different time frames.
