Hi and thank you for replying. I am a post grad student with 36 years nursing and yes I do have a science degree. I have searched about 30 textbooks at our uni library, CKN, uptodate.com and all the usual spots that one would search given my experience.I also asked our nurse educator for assistance and after telling me that its not his job to write my assignment???(I asked exactly what I've asked here) he sent me an email telling me to google it!!!! I am sitting here surrounded by piles of books thinking I obviously have just missed a queue here somewhere? My assignment is as follows. I chose a patient and gave brief(250 words) history, chose one drug that had a primary effect on his condition(frusemide for overload) and wrote 450 words on its mechanism of action.Now have to write 660 words on effects on the different body systems then another 660 words on effects I witnessed post administration and comparison of both findings!! Is that any clearer? thanks again
