IV calculation problem, please help

A patient had 240cc of NG output from 0800-12noon. The physician has ordered the output replaced cc/cc with D5W.45NS with 20 meq of KCL. How much will you give per hour over the next four hours?

Your pt has D5W.45NS with 20meq KCL maintenance bag at 125cc/hr. How much total fluid will she be receiving each hour for the next four hours?

These are somewhat confusing, any help is appreciated.

Thanks

If you are replacing 240 ml over 4 hours, the IV will have to run at 60 ml/hr. (240/4 = 60)

If a bag is running at 125 ml/hr for 4 hours, that would be 125 ml per hour, or 500 ml. total (125 x 4)

(Did I understand you questions correctly?)

Thanks, you made it so easy. I was getting confused about the other numbers.

240cc/4 hours = 60 cc/hour

125 cc/hour + 60 cc/hour = 185 cc/hour x the next 4 hours

Oops! Are the problems related to one another? I assumed they were two SEPARATE problems.
