An IV has been running at 80 ml/hr for 5 hours and 20 minutes. How much solution has been received?

To determine how much solution has been received from an IV running at a rate of 80 ml/hr for 5 hours and 20 minutes, it's essential to convert the time into hours first.

5 hours and 20 minutes can be broken down as follows:

• The 5 hours remain as is.

• The 20 minutes need to be converted into a fraction of an hour. Since there are 60 minutes in an hour, 20 minutes is equal to ( \frac{20}{60} = \frac{1}{3} ) hours.

Now, combine these two time components:

5 hours + ( \frac{1}{3} ) hour = ( 5 + 0.3333 ) (or ( 5.3333 ) hours when expressed as a decimal).

Next, multiply the total time (in hours) by the infusion rate (in ml/hr):

[ 5.3333 \text{ hours} \times 80 \text{ ml/hr} = 426.664 \text{ ml}. ]

Rounding this to the nearest milliliter yields approximately 427 ml. Therefore, the amount of solution received by the IV would be 427 ml, which
