I am a new nursing student. Our teacher is vague to put it lightly. We are doing a plan of care on nausea and vomiting and it asks for the Definition, which I got out of Mosby's, but it also wants the pathophysiology. I am not sure what to write there. I know the definition of pathophysiology, I just don't know how to write what she wants... If you ask her she will just say LOOK IN THE TEXT BOOK, but as a new student with NO experiencing in nursing, duh. I have no idea what the words on a plan of care should be yet. I enjoy learning, but I am convinced they think it is fun to stump the hell out of us with no help So any idea what I might should write under pathophysiology of nausea and vomiting... Any of you use Harkreader? Would it be in there, because I am not finding it.
