I don't see one thing that indicates you have contacted your faculty for help. The one reason that students mess up on NCLEX questions is because they can't separate the factually correct answers from the best nursing answers. The challenge of learning to think like a nurse is huge. Here's something I posted elsewhere on that:
I counseled a student who was dead certain sure that a number of her exam questions had TWO correct answers and she was being unfairly penalized because her faculty wasn't giving her credit for her choices. There were, to her mind, TWO "best answers." Alas , she was wrong on every single one. Perhaps an example will help explain what "thinking like a nurse" means.
1). You are working in an outpatient setting and a woman who is well-known to you comes in with yet another set of injuries from her husband in a fit of rage. She says she will not leave him, she loves him, he is so sorry, gave her flowers, and promises he will never do it again. What do you say to her?
(two of the four answers are totally wrong, so you can eliminate them ... so you have to choose between these two)
a. "And yet you are here again. Let's try to think of a way to keep you safe."
b. "The research shows he will do it again, and it could be worse next time. You have to leave him."
Both look like "good" answers. Both are factually true and contain a second phrase. Which to choose? Well, we know (or will know) that the nurse's job is not to direct care but to help the person along the path to wellness using specific kinds of interventions. Which one of these answers does that? Right, A, because the nurse does not deny the patient's decision (patients are allowed to make bad decisions even if we don't like them) but points out a fact known to the patient ("And yet you are here again") and then offers to engage her in a way for her to make choices about how to plan a way to improve her health (".. a way to keep you safe"). The patient can then discuss options along those lines-- how to recognize the cycle of abuse, how to see when his behavior is beginning to escalate, keep a bag packed, have a cell phone, keep a little money for travel, know the women's shelter hotline phone by heart, how not to internalize his abuse as her own fault, whatever....
While choice B is factually true (he probably will beat the crap out of her again, and it likely will escalate), it denies her feelings and desires (she loves him, she has decided not to leave him), and tells her what to do (even though she has already said she won't). So it will make the patient shut down and not hear another word the nurse says. She's not going to leave him. Saying this offers her nothing she can use. It does not recognize the ultimate nursing value of patient autonomy and does nothing to take the patient along the path towards health.
If this rings a bell, then you have your work cut out for you. Your faculty, believe it or not, wants you to pass and succeed. If you are missing things like this, it's because, probably, you need some help learning to think like a nurse. My daughter is a professor (not of nursing) and had this up in her office:
No one comes in again.
Perhaps they'll all fail."
GO to office hours, every week, twice or three times a week if you have to. Get them to explain the rationales behind the correct answers of the questions you got wrong. Believe me, they want to help you but they will not seek you out. Part of learning to be a nurse is learning how to learn things and get help as a grown-up on your own. Go.
