Intro.., thanks, & can someone please tell me...

  1. Hi everyone,
    I'll introduce myself as a new poster, but long time reader. Which is where the big THANKS comes in. I can't tell you how many hours I have spent reading the posts on this board....laughing, crying, and embracing all the education I can. This is truly a fantastic place. It has taken me at times from being excited about pursuing nursing, to turning my back on it, to reaching back into my heart and saying "yes, this IS what I want to do and be." I am in my mid 30's and have decided to go back to school. I have sold my business to pursue nursing. I finished my CNA last month, and past the state exam this month. I am now going thru my pre-reqs.
    I purchased the book "Nursing Math Simplified", and have a question that I hope someone can answer. On several of the pages it makes reference to a triangle that basically states that 60mg=1gr, 1000 mg=1 g and 15 gr=1g. How can this be? Please, anyone, explain this. I see it as if 60mg is equal to 1 gr, and 15 gr is equal to 1g, that would only be 900. So confused.
    Thanks again, you all are great.

    Hi and welcome to allnurses!

    I'm not sure how to answer your question, sorry. Hopefully someone can come along and help.

    I think they are rounding up.

    60 mg = 1 gr so .06 g = 1 gr.

    15 x .06 g = .9 g (or 900 mg) which rounds up to 1 g.

    Actually to be techinical; 1 grain = 0.06479891 grams, so if you use that you get and answer like .971.... which rounds up to one.

    Unless you travel to a foreign country, you will never see anymedication measured in grains. Rarely, an old school doc will order something like "tylenol 2 grains", but 99.99999999% of the time the docs don't use grains anymore. Small comfort I know, because you still have to learn it to pass.
