I'm having a really hard time understanding math for nurses when calculating heparin units, can any one help?

Heparin comes in various concentrations\n1u /cc\n10u /cc\n100u /cc and many others\n\nALL YOU HAVE TO DO IS USE THE FOLLOWING\n\nDesired units &#92; concentration\n\nif you want to give 12 units and you have 10u /cc\nthen the answer is 12/10 =1.2cc

Do you have a specific model? Or is it just an overview? Check out books by Roper, Logan and Tierney, they're quite good. Also book " Best nursing practice" i can't remember author but she gives a very good demonstration of care planning, implementation and evaluation. I bought it but i don't have it at the moment (Only partly moved into new home)\n\nNMC should be able to help you (Check out their literature for nurses, starting with the Code Of Practice, then ask RCN because they  can provide information. If you go to nursing standard online (You'll need to register but it's free) and enter what you wriote in your question, their search engine will come back with lots of articles you will find sueful for your essay.\n\nGood luck!

I would assume that one of your .01s in column A is something like 0.012.\n\nChange your number  format to General and see what happens.

Hi Vicky! \nLet a=32deg, p=patient’s weight, then f1=p*sin(a) is the force pulling him down along the sheet & f2=p*cos(a) is the force pressing him to the sheet, so when k is coefficient of friction, then \nat the moment to start slipping from the bed f1=k*f2, thus k=tg(a). the more k the more “adhesive” the patient feels.

All of the above reasons. Plus, if a patient is on heparin, he/she will have elevated aPTT levels too.

You need to get your units in a consistent form.  I suggest changing the velocity of the electron to 2.5E6 m/s so when you divide it into c-----------WAIT A MINUTE!-----Yor formula is NOT right, because you're dividing a speed by a speed, which will give a dimensionless answer.  Wavelength is a LENGTH, so the answer must come out that way.  I forget the formula you're refering to, but what you've typed isn't it................

Most of the math in anesthesiology is in computing doses, either as mass per unit body mass (milligrams per kilogram body weight is the usual) or per unit body surface area.  That latter, of course, may need computed, too.\n\nSome of the math involves making allowances for impoverished renal function--if the kidneys are malfunctioning you have to do dosage adjustments.\n\nAnother batch of the mathematics may involve fluid replacement during surgery, but that's usually controlled by the surgeon, to be honest.\n\nMost of this is not heavily used; you quickly learn that an adult will take about this much of whatever, and may need a little more--so you start with what's usual, and adjust as time goes by.  The amount of real time mathematics in anesthesia is pretty slim.  In point of fact, most physicians use very little math in their day to day activities, and what is used is pretty simple stuff.

just look at your units..that normally hleps\n\nhf ...kj / mole\n3.22 kJ / 6.02 Kj/mol =    x moles\nxmoles * 18 gram / mol.....  Thats your answer

Sure,\n\nRemember it is x units, therefore although you are correct that taking the derivative and setting it equal to 0 yields a value for x of just over 5.5 units you have to round it up to 6 units, under the assumption that x is in whole units per day. That's alright for a daily figure but 6 is incorrect if you are producing amounts averaged over longer periods of time. In short: you are correct and the answer in the book is stupid! Technically though, if C'(x) is your derivative function then you need to establish that C'(6) is closer to 0 than C'(5). C'(5) = -0.4 and C'(6) = 0.274, so C'(6) is closer to 0 and is the correct answer to a stupid question. lol.\n\nYou do have the correct cost function C(x)\n\nC'(x) = 1.2 - 200/x^3\n\nC'(x) = 0 when x^3 = 200/1.2 = 166 2/3\n\nx = 5.503

Firstly, it should be done by a healthcare professional...either a doctor or a diabetic nurse.  It is calculated based on individual response. So it is really a guess game. You give some insulin, see what a sugar value is in several hours and adjust based on that.  After several days, you arrive at a reasonable dose.  Hope this helps, but don't try this on your own :).

you want me to do your homework for you? I think not.\n\nI worked for about 10 years in a clean room and did this very stuff all day long. So perhaps I can provide some hints.\n\nI will tell you how to do the vancomycin question, and the first Pen G question in hopes that it well help you figure out how to do things.\n\nIf the final volume is 20 ml and you are adding 13.8 ml water then the volume of the powder is 20 minus 13.8 ml. The answer is 6.2 ml. I'm not sure where they are getting their vancomycin from, but they got some huge purity issues. Commercially available vancomycin is about 1 gm per ml.\n\n\nOK you have 5 million units diluted to 250,000 units per ml. \n\n5,000,000/250,000 = 20 ml subtract out 18.2 ml equals 1.8 ml powder volume. Oops, that's the answer to all four question\n\nNow let's see if you can answer what the volume for 2 million units would be.

As far as nursing school is concerned, yes, algebra is helpful, but the algebra used is fairly simple/basic.  It is mostly solving for x, or filling in a formula with values, but you will need to know how to set up an equation based on a information provided.  \n\nMost nursing schools will test prior to admitting a student, and then to move on each semester, some schools will test again.  My school drops a student from the program if the student does not pass the test with at least 95% the second time.\n\nAs far as on the job, algebra is also utilized, however, as a safety measure, pharmacy and/or other nurses are always around to provide assistance when one needs to verify medication dosage.  If you work in an ER, you need to be good with your skills, because there may not always be someone around to assist you in math.\n\nHope that helps.

this is the best i could find. i looked everywhere on the web and found nothing. hope someone else can help more.\nhttp://www.ifafitness.com/health/loadcalc.htm

Here is the actual formula:\n\nColony forming unit / mL = cfu/mL = # of colony * (1/dilution factor) * correction factor\n\ncorrection factor is the reciprocal of the volume you used in inocculation.\n\nOverall for your sample -->\n\ncfu/mL= 280*(1/10^-2)*(1/10^-1) = 28 * 10^4

keeping with the same unit fractor harry is correct.\n \n .2 ml

Check with your state board of nursing.  They will be able to tell you.  Most state boards now have on online site where you can email them...that would be the best way to go.  Get the info straight from the source.
