    hi, luv4nursing
    Congrats for coming this far. I just graduated myself, and know its tuff. I too stressed all the way. I have a little help for you w/ the math. A good friend of mine could not get it for anything, until I convinced her to use my method (this after several instructors gave us several versions for figuring about confusion). If you can just remember : D
    ---- x V =dose
    This means: "desired" (whats ordered), over what you "have" available, times "volume" (which is per ? mg, ml, etc)
    It was our experience that whatever the problem, this method always worked. I take it you are only in Pharm 1? It gets a little more complicated in Pharm 2 and 3. (we had all 3 where I went) Practice w/ this, I hope you understand better. Please let me know if I helped. If I can help any further, you are welcome to email me. Good Luck, I am sure you can do it.

    sorry, the formula was suppose to be:

    ------ X V

    I hope this one makes more sense

    luv 4 nursing---hey, I live very close to johnston city. Moved here 5 years ago from a big city..boy things are different. Johnston City is the happen place around here. There is one associate program here. It is over satelite and has a big long waiting list to bridge to Rn. I worked at a restaraunt in Johnston City while in school. Hint-major seafood-worked with lots of ETSU students. Good Luck to you and it sure is a small world..cj

    Hi, one of our textbooks was "Math for Meds". It broke things down very simply for me. However, I ended up doing my formulas like this:

    If 20 mgs is to 1 ml, what is 15 mgs to x ml?
    Written as: 20 mg:1ml =15 mg :x ml
    Remove the mg and mls
    Now you have 20:1 = 15:x
    Now, multiply
    20 times x = 20x (multiply your two outer numbers)
    1 times 15 = 15 (multiply your two inner numbers)
    remove the x from 20
    Now, divide:
    15 divided by 20 = 0.75
    So, the formula is:

    My instructor always laughed at me -said I was doing the formula backwards BUT as long as it worked it was OK! As I look at it now, it appears hard but it's really not! Take your time and break it down. I still use this today...Good luck!

    Sorry but these post seem to be more concerned with drug dosage than with Pharm.
    According to our instructors Pharm is all about drug classes, blah, blah. Did you not already have drug dosage in the first semester??
