Seriousely,do you even use algebraic equations ? - page 3

Since you are only as strong as your weakest link,I would like to know if you use algebra in your daily routine.If you do use it, then to what degree and how is it applied? I know how to do the operations for a test but I do not... Read More

    Other than setting up some basic ratios to calculate dosages, etc, no.

    I'm not a nurse yet (I'll be entering nursing school this fall), but I've looked through some of those calculation books and it seems that basic math and conversion factors are the nuts and bolts of general nursing. I'd rather use algebra than calculus any day. I think the pre-meds have it worse. ALL of the doctors I've talked with say that they do NOT use calculus in their practices. Most pre-med advisors and med. school admissions boards say that "Calculus teaches you to THINK. You'll need these strong thought processes to succeed as a doctor." What a crock! Calc is usually just a weed-out class.... give me algebra ANY day!

    We use algebra for med doses, and I & O's and calorie counts. We do daily calorie counts, and with a baby on TPN, lipids, and just starting feedings, it's
    quite complex. I do much better with a calculator!

    I do use them to do dose calculations on PRN meds. Like for example Dilaudid comes in 2mg/ml carpujets and some physician will order .5 mg which barely fills the syringe but oh well.

    In 12 years as a nurse, I have only needed to use one equation; the solve for X ratio and proportion problem. This is the only algebra I've ever needed for dosage calcs.

    My husband is an engineering scientist, and he uses algebra, calculus, etc every day. Then again, he sometimes works on algebra problems just for fun.
    He's a little weird.

    In nursing prereqs, algebra is often a weed out class.

    In fact, it almost weeded me out.

    Someone asked for an example of a math problem. I work in an ER...our Fentanyl comes in 100mcg/2cc vials. Order is to give: 50mcg IVP of Fentanyl:

    So...you have 100mcg/2cc = 50mcg/x (what you want to give)

    You then multiple the 50mcg X 2cc = 100 and divide by 100 to get 1cc which is the volume you need to give. Does that help?? In ICU/ER you also have drips based on kg. For instance: Dopamine is usually started at 5-10mcg/kg/min so you factor in the concentration of the drug and go from there.

    thanks for the example! i still have a long way off before nursing school (doing bsn prereqs while i wait) but i am in college algebra currently and just needed to see if the algebra you guys are using is worse than this class.
