Nitro versus isosorbide

Yes, your pharmacology book. :)

And Google.

I used to tell my ADN students that yes, they had to learn basic cardiac and pulmonary meds and concepts because everyone in our care had hearts and lungs. Does ADN nursing school not do that anymore? I mean, nitrates for angina are not rare, not new, and certainly not complicated. My students learned these meds in the first semester.

OK, so it's September and this is the first semester, and the OP is there. OP, some quick advice which will serve you well as you embark upon your nursing education: The works on the book list they give you for the bookstore generally have this sort of basic information in them. When you need information about medications, you should have a nursing pharmacology book -- there are many -- and if they didn't have them on your reading list you should go to Amazon and pick one up. The Nurses Drug Handbook is the classic; having it on your desk would save you a lot of time and give you the background your faculty will expect you to have to teach your patients, too.

Welcome to nursing!
