tiffany311. . .all i do is work calculations by dimensional analysis when members post them on the forums. i try to type an explanation of what i am doing along with some of my replies. you can see some of them on the dosage calculations thread in the student assistance forum (http://allnurses.com/forums/f205/dos...ons-88867.html). you can find other threads that i've responded to by doing an advanced search and using for threads with the word "dimensional" and my name "daytonite". i am not an instructor.
