Pharmacology calculations

  1. 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.

    Here is an example of one of problems:
    Ordered: Humulin regular U-100 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.

    I found an excellent program that runs in a Windows environment. It is called Calculating drug dosages. I paid about 45 dollars. purchased it at Amazon.com . it is by Sandra Luz Marinez de Castillo and Maryanne Werner-McCullough.

    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.

    you don't need a website, just go with what info you have and what you need.

    (250ml / 50 units) * 7 U/hr = 35 ml/hr
