Pharmacology calculations

0 Hi
I am in Pharmacology this semester. We have had a total of 3 quizes on various calculations this semester. The last quiz is going to be on Ped's and Critical Care Calculations. The text leaves a lot to be desired on explaining the cals. There is several different methods to use to get to answer. I was wondering if someone would have advice on a method that works well for them in doing these kind of calculations....
Thank you.

Ordered: Humulin regular U100 7 units/hr. The IV Solution has 50 units of Humulin regular insulin in 250 ml of normal saline. At what rate in ml/hr should iv infuse?
I was just wondering if someone knew of good nursing website regarding these kind of caluations. Thank you.

The program allows you to select the method for solving the equation, then walks you through how to solve it. I passed the math test with 100% the first time.
