Calculation Question

  1. Am I doing this right?

    Order: grain 1/100 for injection from a solution of grain 1/150 per mL. How much should be administered?

    (1/100)/(1/150) x 1mL= 1.5mL

    Order: Morphine grain 1/6 IM for pain. Available: Morphine grain 1/4 per mL. How many mL to administer?

    (1/6 gr)/(1/4 gr) x 1mL= 0.66666667 = 0.67mL

    Also, how often do you get an order in grains either in a hospital or clinical/office setting?

    I have never seen an order for grains.

    Yes. Yes. It's pretty rare. One of our older doctors will order Tylenol and Codeine in grains.
