How are you studying? What types of questions are you getting wrong? Do you go over your test results with your professor to see how you can improve?
"Situational questions" will be asked more and more throughout nursing school. It's no longer enough just to memorize things, although that is imperative as well, you need to find ways to apply the knowledge and the concepts to a situation and arrive at the most correct answer.
My studying methods won't necessarily work for you because it's based on both my own learning type, and on the resources my professor and my program make available to me. But what I do is record every lecture, and save every Power Point from each lecture. When I'm super motivated, I save both things to my iPod so I can have it at my fingertips where ever, whenever. But that's not necessary, just handy. The key for me is to go over these things over and over until I'm familiar with the things my professor emphasizes, and then read the book chapters, concentrating on things related to what my professor emphasizes in class.
For example, my Med-Surg professor's pet word is "vascular". I'm starting to realize that with every body system and disease process, there's almost always some "vascular implications". These are life-or-death implications. So with each process, I'm paying special attention to anything to do with circulation, anything to do with vital signs, etc. These always pop up in his tests in one way or another.
Every once in a while, sit back and try to think what it is you need to know, besides what they're telling you directly. Work on memorizing lab values, they don't "teach" that in my program, they just expect you to know them. Before you ever knew what a BUN/creatinine was, they were asking what low creatinine clearance looks like.
Anytime you can find somewhere you can use a mnemonic device to help you remember something, use it. For example, with BUN and creatinine, I know the levels are 10-20 and 0.7-1.4 (according to my book, anyway). BUN is written in BIG letters, and its value is the bigger number. That leaves the smaller number, which is 0.7-1.4, which I remember because um... well, I like 7, and 0.7 doubled is 1.4. LOL that's a bad example, but you'll find your own ways to remember things.
It's overwhelming, I'm there too. Determination and critical thinking will see us through.
