Basically the pt is getting a litre of fluid over 8 hours.1000 divided by 8 is 125.The pt is getting 125 mls/hr.

Fluid volume: 1L=1000ml. Infusion time: 8hrs

Formula: Volume/infusion time

1000ml/8hr=125ml/hr

it has nothing whatsoever to do with the pitocin (spelling) and potassium.

this is a straightforward division problem. no "formula" is necessary.

if you give one liter of fluid over eight hours, how many cc/hour is that?

you should be able to do that in your head: one fourth of 1000 is 250, and half of that is 125. or divide 1000/8 = 125.
