Dosage calculation DA vs other?

[Mrs2016]

I'm learning Dimensional analysis for med math, but I was wondering if there were other ways of doing med math and what the names of such approaches are called. I want to learn a second way of doing it, incase I brain fart on DA. Thanks for any input.

I like being able to read a word problem and figure out what they're asking. My only caveat about DA (other than it is often more complicated than necessary) is that so often I see students try to cram every possible bit of data in the question into the equation...and a lot of it is not needed for the answer. Examination writers know this and put distractors (wrong answers) that would result from doing that in the choices. Does make for a lot of confusion, and we see it here often.

Step back from every problem and ask what's really being asked, see if you can eyeball a possible answer range, and then determine how to solve for X in any way that works comfortably for you. If it takes two steps, so what?
