I did a search but couldn't find a discussion on this exact subject, so here goes:
Is one method truly better than the other or is it (like most things) a matter of personal preference? I've been messin' around with both using Pickar's "Dosage Calculations" for ratio/proportion and Medication Math for Nursing Students, http://www.alysion.org/dimensional/analysis.htm#guide
, for DA.
From my perspective, RT is way more comfortable for me than DA. I get so confused with how to line up the pieces of DA that I simply give up on it and just go to the formulas of RT which yields the answers quickly (and to me simply).
Hmmm, I guess my real question is, what method will my school want me to use? The book we're supposed to get is Calculate with Confidence (which is on its way now) that includes instruction in both methods
I'm figuring that if I consistently get the right answers, the instructor won't really care what method I use....

I always knew how to do ratio and proportion, but it just seems like so much extra work, and easier to make a mistake. i went out and bought the DA book by Anna curren and i love this method. Its so easy to learn and i think safer to calculate dosages. I did not know anything about how to calculate dosages, and thats scared me, so i wanted to learn before i started school next month and a few eeks ago i went and bought the book(DA for Meds) and in that little bit of time i learned how to calculate dosages.. i can even figure out body surface area, titrate iv, flow rate etc. i think DA is the best, our school i think is going to show us all the ways to do it and we pick the way that we think is easier, i am definitely going to stick with DA
