    I love Med Math, I was so confused when I was in a Nursing school but I didn't give up. I taught myself for straight 2 weeks (my instructor was so confusing she wasn't helping at all) and since then it became my favorite. xoxo

    Hi there! Thank you so much for your videos! They are the most helpful, least complicated, conscise, empowering nursing math videos I've come across. You have a very nice accent too and I was wondering if you could do a video on dehydrated patients based on the patient's weight, hydration deficit, maintainence fluids, and ongoing losses. I'm going into the Veterinary nursing field but our math problems are generally mostly the same or very similar. You're my favorite math instructor and thanks again! Keep up the great work!

  • @danielp3772
    @danielp3772 11 років тому +2

    Candy, if you get to round up a number look to see if it "goes up or comes down" EX: 83.3333 it goes down to 83. if it would be 83.5 it would be rounded to 84. every time you see 5 or higher it goes up, if it is below 5 it goes down.
    (82.3= 82; 83.6= 84; 83.9=84; 83.452=83.5; 83.23=83) so look at the numbers that come after the decimal point if it is greater than 5 it will round up the number ahead of it 83.45= 83.5, or 83.455=83.5. I hope it helps you.

    I've seen pretty much all of your nursing math videos. And I was wondering if you were going to do one on the safe rates for orders.
    Here's an example: A Physician has ordered 200 U regular insulin in 500 ml NS to be given at 8 U/hr to an adult male who weighs 176lbs. The recommended adult IV dosage of regular insulin is 0.1 U/Kg/hr. Is the dosage safe?
    I've been trying to work on stuff like this, like for this one I know that the order is 8 U/hr the supply is 200U/500ml, his weight is 80kg. I've got an issue getting the dimensional analysis in order for ones like this though. Do you think you can help?

    I think, He mistakenly press the number in the calculator. 40,000/160=250. Or He multifly 8hr x 20 instead of 60dpm=160. But it was great, easy to remember.

  • @shannonsmith9012
    @shannonsmith9012 5 років тому +1

    Got a question. For the last question (1600ml over 8 hours) If you divide 1600 by 8 hours wouldn't that give you the ml/hr not the D.P.M.? Wouldn't you take the 200ml/hr and divide by 60min?

  • @aimeew6930
    @aimeew6930 9 років тому

    I have a question..
    Earlier you said when calculating drip rates, to always round up. Yet during the corrected question with the answer 83, I calculated 83.3 - should it be rounded up to 84? or is it still general rounding up and down rules??

    • @servicedepartment1696
      @servicedepartment1696 9 років тому

      of course you need to round it up, because you cant measure 0.3 of a drop, therefore you will round it to 83 drops, because its 83.3 if it was 83,5 or 83, 6 then you would round it to the next whole number.

    • @aimeew6930
      @aimeew6930 9 років тому +3

      Technically that's rounding down.
      I was trying to clarify what was meant by "round up" - whether it be round up to the nearest whole number or rounded in general up/down method.
      It is ground into me from my casual job to round UP no matter what the price. eg: $12.91 has to round UP to $12.95.. goes against all math laws, but that's just one way discount companies catch their customers.
      So I felt I needed to ensure the term "round up" did or did not mean literally 'up'.

    • @Systolic120mmHg
      @Systolic120mmHg 8 років тому

      I got 17 drops per minute. 10gtt/1mL x 50mL/30 min = 16.7 gtt/mL rounded up to 17. Here, 1 gram cefarzolin is constituted inside the 50mL, and so that may confuse others as to where we would put 1 gram in the equation, but it is not necessary at all.

    @ArabSicily 9 років тому

    What is an easy formula if you do not have the numbers of hours given in the problem? Example: "Lidocaine IV drip 2 grams/250 ml to infuse at 4mg/minute. How many ml/hr should be administered?" I know that we will have to convert grams to mg,therefore this will turn into 2000mg. Thanks!!

    • @tecmath
      @tecmath  9 років тому

      ArabSicily 2 grams/250 ml to infuse at 4mg/minute. This equals 2000mg/250ml as you have said.4mg per minute means 240mg per hour (4mg x 60)So if 2000mg : 250ml 240mg : ___ml2000 / 240 =8.333250 / 8.333 = 30ml required.or, This is a Stock Required (mg)/ Stock Supplied (mg) x volume (ml) = 240mg / 2000 mg x 250ml = 30ml
