I'm studying for a quiz in a few weeks, and i need some help on some sample problems. Parenteral: Physicians order: Morphine sulfate gr 1/10 IM q3h for pain; Supply on hand: Morphine sulfate 8mg/cc. Give in cc(s)? Am i supposed to convert 8mg to grains? And then do i multiply .13 grains and 10? I end up with .13 cc, is this correct?

First you have to convert grains to mg. Depending on your text 1 gr= 60-65 mg. Using 60 mg as the conversion amount you need 6mg of Morphine. Next you need to divide the amount of morphine supplied into what you need to find the cc. (6/8=dose) The answer is .77 cc

Easier to do the other way around. The order is for about 6 mg., so give about 3/4 ml, and remind your teachers that error-reduction programs now suggest using ml, not cc, in orders and medications ( if you can't scintillate with science, blast with bs). There are actually about 64 mg in a grain, but in medicine/nursing 60 mg is a traditional round-off.

An easy way to remember the conversion from grains to mg is thinking of a clock --> 60 mg = 1 gr
I like to use the formula Desired / Have times Quantity
