b.s. . .i suggest you go back to your course syllabus and course objectives to see what is specifically listed to give you a guideline of what you need to know. you should also have a copy of a good nclex review book similar to saunders comprehensive review for the nclex-rn examination
, 3rd edition, by linda anne silvestri which has a chapter on cardiovascular problems and you can find specific hematology or immunology subjects through the index in the back of the book. they list the signs and symptoms and nursing interventions of diseases. there are also nclex type questions included for study. another book that might be helpful is pathophysiology: a 2-in-1 resource for nurses
by mosby which also has chapters on cardiovascular and hematologic diseases. beside the pathophysiology and medical treatment, it also gives nursing interventions. for thumbnail outlines of the medical diagnosis, testing and medical treatment of cardiac and hematologic diseases, use the family practice notebook sites and link into the chapters of interest or you can search for specific diseases with the search box in the left upper corner of every page: http://www.fpnotebook.com/cv.htm
it would probably also be a very good idea to review these subject areas in a pathophysiology textbook.
welcome to allnurses!
