Thanks so much

If you don't mind me asking, Im sorry in advance Im really new to nursing, What is PICU ?

Good God. Thanks Chare. thats what I get for trying to go math first thing in the morning. LOL. Sorry

I don't think the computer is wrong in this case. Heres how i did you problem. FYI I am taking my program's math for Health Sciences course right now, so this is exactly what we are doing. 1) First you have to convert the 0.4 mcg to mg. So 0.4 * 1000 = 400. 2) now you have a prescription of 400 mg. 3) Set up your problem like a ratio problem. 500 mg/ 2 mL = 400 mg / x 4) Use cross multiplication to solve for x. So you should now have 500x = 800 5) Now divide both sides by 500 to get x. 800/500 = 1.6 6) So your answer is 1.6 mL Make sense? If not let me know. I'll keep an eye on this conversation if you have any other questions. Or if I did something wrong let me know :) Hope this helped.
