If 1 liter is infused over 8 hours, what is the rate of infusion in ml/hr?

To determine the rate of infusion in ml/hr, you first need to convert the volume from liters to milliliters. Since 1 liter is equivalent to 1000 milliliters, infusing 1 liter means that 1000 ml will be administered.

Next, you divide the total volume by the total time in hours to find the rate of infusion. In this case, you are infusing 1000 ml over a period of 8 hours.

The calculation would be:

Rate of infusion = Total volume (ml) / Total time (hr)

Rate of infusion = 1000 ml / 8 hr

Rate of infusion = 125 ml/hr

Thus, the infusion rate is 125 ml/hr, which corresponds to the selected answer. This method of calculating infusion rates is crucial in pharmacy practice as it ensures that medications and fluids are administered at the correct speed, maintaining safety and efficacy in patient care.
