    How many times does 1.5 (ml/minute) go into 6 (ml)?

    Or, to put it another way, what do you need to multiply 1.5 by to get 6?

    Because this is supposed to be a word problem I'm wondering if there's something missing....like a word. Or perhaps there's an error or it's one of those professional calculations that seem weird to the majority of us. So I give you.....

    Is that calculated using the Dimensional Analysis, Ratio Proportion & Formula or Desired Over Have method*? I think that if the OP wants to be a nurse then they calculate dosages a different way. I'm only saying this because I remember my sister the nurse talking about this kind of stuff.

    *Found these fancy methods on a nursing education site.

    I dunno. The answer looks pretty obvious to me.

    Agree 100%. However if OP is my nurse, I don't want him administering my IV.

    Read up a bit on Nursing math and I think OP is confused because flow rates are expressed in mL/hr, not per minute because they say the IV pumps rates are calculated per hour. The formula I'm looking at says....

    Total Volume ordered in mL over(divided by) Time in hrs = fluid in ml/hr. In this case you end up with a converted flow rate of 90mL/hr thus 6ml requires 1/15 (6/90)of an hour or 4 mins.

    I think the Nursing society has tried to come up with a standardized method of calculation so even those terrible at math can figure things out. Personally I'd prefer my nurse to have good math skills but unless you were their teacher the rest of us will never know. Make you feel comfortable?
