Unit IV Math help!

looking for units/hour

25,000 units/500ml x 7ml/hour = 175,000 u/500 = 350 units/hour

(the two "ml's" will cancel each other out and you are left with units/hour)

You are very welcome!

The way I was taught to is to see what the question is looking for in the answer. (like ml/hour or gtt/min, etc) Then you set the problem up by putting what you need on top for you answer first and on top, then what you need on bottom for you answer next and whatever info is left and any conversions that may be needed. Anything with same units (ml, units) on opposite sides will cancel each other out. You should only be left with units that you need in your answer. (hope that makes sense) And then you just do the math by multiplying everything on top and then everything on bottom and then dividing the two of them.

500ml x 1200 = 600,000
25,000 x 1 hr = 25,000

then divide 600,000 by 25,000 to get 24

Oops...sorry....I put an explanation to your other problem up.
Same concept though.

25,000 x 7 = 175,000
500 x 1 hr = 500

175,000 divided by 500 = 350

Does the question possibly say the dr is increasing the drip BY 500units/hr?
100units = 1 ml
The patient is already getting 7ml (or 700 units) per hour, if you increase it BY 500 units (or 5ml) then the answer would by 12ml/hour (7ml+5ml).
