    Another dimensional analysis or factor-label method link. I didn't read through this entire thread to see if it's already been posted. Also has a few practice problems in units conversions, which (glancing at questions in these threads) seem to be what's confusing people the most.

    This is the one that I used to pass my Dosage and Calculation. We were required to have 100% on the test and I passed it. You should probably also memorize conversions (F to C and lbs to kg especially)

    How Do i solve this problem?

    You are to give Aqueous Penicillin 600,000 Units. Available Aqueous Penicillin (powder) 1,000,000 Units per vial. Add 3.6 mL sterile water. Prepared solution will then be 250,000 Units per mL.

    What will you give to your client?_____

    250,000units: 1mL :: 600,000 units : XmL

    250,000 X = 600,000

    X= 2.4mL

    Thanks. that is a simple problem but I never knew that 250,000 units = 1 ml. I don't remember it being taught to me.

    the label gave you the final solution of 250,000 units per 1ml, each label will have a different final solution ie 100mg per 1ml, 100,000 units per 2ml, does that make sense, in other words read the label for the final solution, not that 250,000 units will always equal 1ml.

    I was going to say what mb said...always dissect your problem and use the useful info and toss out the rest. If the problem is on paper cross out the extraneous stuff (or the stuff they put in to confuse you) and then you will see the "meat" of the problem. I used Ratio and Proportion on that one, I do that on all problems except IV drip rates; those I use Dimensional Analysis on. Good luck and feel free to ask for more help! I just graduated in May and I struggled with the math until the last semester of school, then it just seemed to "click".

    I was wondering, is there a sticky or a special site that can be coordinated for "math sufferers". Perhaps, beginning calculations or shall i say the basics..simple to complex...step by step on how to calculate. I'm a visual learner, numbers and I don't work well. I am trying, but I've got a block!

    This will come in handy once someone puts something on here. I've already had Algebra, but have to take it again. Bummer!!!1

    Does anyone know what the easiest way to solve this problem is? Thank you!

    Your client ate 60% of a 16 oz steak. The steak is 45% protein. How many grams of protein did your client eat?
