Final answer:
The infusion rate for a 1000 ml IV bag that needs to be infused within 8 hours is calculated by dividing the volume by the time, resulting in a rate of 125 ml/hr.
Step-by-step explanation:
To calculate the infusion rate for a 1000 ml IV bag that needs to be infused within 8 hours, you need to divide the total volume of the IV fluid by the total time in hours. The infusion rate is often measured in milliliters per hour (ml/hr).
Infusion rate = Total volume (ml) / Total time (hours)
In this case, the infusion rate would be:
Infusion rate = 1000 ml / 8 hours = 125 ml/hr
Therefore, the IV bag should be set to an infusion rate of 125 ml/hr to ensure that the patient receives the entire 1000 ml within the 8-hour period.
