At what time should the nurse expect to hang a new IV bag after starting a 1000 mL bag of 0.9% normal saline at 80 mL/hr starting at 0900?

To determine when to hang a new IV bag after starting a 1000 mL bag of 0.9% normal saline at a rate of 80 mL/hr, it is essential to calculate the total infusion time for the IV bag.

First, calculate how long it will take to infuse the entire 1000 mL bag. Since the infusion rate is 80 mL/hr, you can use the following formula:

Total time (in hours) = Total volume (in mL) / Infusion rate (in mL/hr)

Plugging in the values:

Total time = 1000 mL / 80 mL/hr = 12.5 hours.

Next, since the IV started at 0900, you need to add 12.5 hours to this start time:

0900 + 12 hours = 2100 (which is 9:00 PM) and then adding the additional 30 minutes will give you 2130 (which is 9:30 PM).

Therefore, after infusing the 1000 mL bag over 12.5 hours, the nurse should expect to hang a new IV bag at 2130. This calculation reflects an accurate understanding of how to determine
