Final answer:
To find the flow rate of intravenous fluid in mL per hour, divide the total volume (600 mL) by the number of hours (3), resulting in a flow rate of 200 mL per hour.
Step-by-step explanation:
The patient is to have 600ml of intravenous fluid over 3 hours. To find out the flow rate in mL per hour, we would divide the total volume of fluid by the total time it will be administered over. The flow rate (Q) can be calculated using the formula:
Q = V / t
where V is the volume (600 mL) and t is the elapsed time (3 hours). Therefore, the flow rate is:
Q = 600 mL / 3 hours = 200 mL/hour
So, the intravenous fluid flow rate is 200 mL per hour.
