Answer:
50mg per hour.
Explanation:
I am assuming that there is a total of 1 liter of this medication being administered, and it has only been 5 hours since treatment has started. If the patient has received 250mg of medication over a span of five hours, you simply divide the amount given by the time:
250/5 = 50
So, the patient has been receiving 50mg of the medication per hour.
