In NS they teach us to use dimensional analysis when faced with med math. I am curious if practicing nurses actually use dimensional analysis everytime they are doing a calculation, or does it just become second nature?
Ex: The order is to administer 4 g of an antibiotic mixed in 100 mL to run over 40 minutes. The tubing label reads 15 gtts = 1 ml. What is the drip rate of the infusion per minute?
I know the answer is 38 gtts/min -- however, in the hospital do nurses actually whip out the pen and paper and do dimensional analysis, or what? Just curious! :)
