Some might consider this cheating, but I would look up your textbook on quizzle and read every test question related to the topics on your test. I wouldn't stop with just your textbook though. I believe sample tests from other textbooks are just as helpful since people post test banks from a number of texts on there. I don't know what it is, but some nursing questions are just so tricky you have to have seen the question before and then you can answer it every time after you have seen it. I recall one question about giving someone soup versus plain water if they are dehydrated. Never going to get me with that one again.
