A client needs an infusion of 1 liter over 12 hours. What should be the flow rate in ml/hour?

To determine the flow rate in ml/hour for administering a 1-liter infusion over a 12-hour period, you start with the total volume that needs to be infused and the total time for the infusion.

First, convert the volume from liters to milliliters. Since 1 liter is equivalent to 1000 milliliters, you need to infuse 1000 ml. Next, to find the flow rate per hour, you would divide the total volume by the total time in hours:

1000 ml ÷ 12 hours = approximately 83.33 ml/hour.

When deciding the appropriate flow rate, it’s common practice to round to a practical figure. Given the choices available, the option closest to 83.33 ml/hour is 100 ml/hour. This flow rate ensures that the infusion is completed in a timely manner while also accommodating slight variances in flow that may occur during administration.

Thus, selecting 100 ml/hour as the flow rate effectively ensures the goal of infusing 1 liter over a 12-hour period is achieved, taking into account practical rounding.
