Im getting ready for my Math Final tomorrow. Can anyone tell me what the rules are as to when to round and when not to. Just when I thought I knew my teacher changes it. Thanks!

Sorry I meant to ask when to round to the nearest tenth or hundreth or whole number. I know gtt are to the whole number as is insulin. But just wanted to know if there was a concrete rule out there.
beth66335, BSN, RN 890 Posts Dec 12, 2007 Oh I see, well our teacher told us you should always round gtts to whole drops (up or down based on the 5 rule). Most med problems come out to the nearest 10th that I've done unless I'm getting the wrong answer!lol

Daytonite, BSN, RN 4 Articles; 14,603 Posts Specializes in med/surg, telemetry, IV therapy, mgmt. Has 40 years experience. Dec 12, 2007 I think that what you may be referring to is how to determine what the significant digits are that you need to round to when you are doing calculations. There are set rules for doing this and I remember being given them in either my pre-algebra or Algebra I class. It has to do with the numbers that go into the calculations to begin with and how many decimal places they have. I've been trying to find some websites with these rules for you:http://home.uchicago.edu/~freed/sigfigs.htmlhttp://dl.clackamas.cc.or.us/ch104-01b/signific1.htmhttp://www.phys.unt.edu/PIC/significant_figures.htmhttp://members.aol.com/profchm/sig_fig.html

I'm so glad you are!
caliotter3 38,333 Posts Dec 12, 2007 I was always taught that if it is 5 or above round up, and below 5 round down. Seems pretty simple. Good luck on your final.
09RN 289 Posts Specializes in ICU, Mother/Baby. Dec 13, 2007 I wanted to Thank everyone! I took my Final today and I passed! We had to make a 90 or higher to pass. We lost 6 people today which I hate! Im very thankful to have this board to help me clarify things before a big test like that one! You are wonderful!! Hope everyone has a great holiday!
miss arron 156 Posts Dec 15, 2007 my method:gtt and insulin are whole (duh)tablets are either whole or half values (ie 2 tablets or 3.5 tablets, never 3.4 tabs, 0.7 tabs, etc)adults - round to 10thpeds - round to 100thchemo - round to 100th*unless directions say otherwise*
