your instructor is giving you test questions to examine what she wanted you to learn about the specific content of the material and not particularly what the professors version of the text book was. that is only appropriate and her right as your teacher. how else can your instructor know if you have learned the concepts she wanted you to master? the textbook version of the test, like the nclex, is going to cover what the textbook writers felt you needed to learn and covers material important to the widest range of learners. they are often only skeletal frameworks.
i think what you are missing is that your instructor is using her tests and the discussion afterward to help sharpen your critical thinking skills. i'm sure she doesn't intentionally mean for each test question to become controversial. what is happening is that after the test you are being exposed to some of that review process and being allowed to exercise some critical thinking that perhaps your instructor failed to consider when composing her tests. none of us is completely perfect or fair and we all have something to learn including you and your instructor. take some pride in knowing that you are having a part in the development of these tests.
as far as nclex is concerned, nclex questions are designed for a very broad population of test takers and is a test of your minimum
knowledge of nursing. questions on the nclex are carefully checked for fairness and that they don't delve too deeply into specifics that one school might teach while another might not. medical and nursing treatment also varies from area to area of the u.s. each nclex question undergoes a rigorous process of being reviewed by boards of many, many people to assure this fairness before it even makes it onto the actual test that someone takes. your instructor doesn't have that available to her, but she has you students and your thoughts to help her fine tune her test questions.
the majority of nursing students enter nursing school not understanding what critical thinking is. it has always been the dilemma of nursing educators of how to teach nursing students to rationalize out solutions to problems. most students have to be dragged kicking and screaming into learning critical thinking. however, as rns we have to be able to solve problems and manage patient care on a daily basis and being able to think critically is a huge part of that.
it is unfortunate that you dislike scrambling for points on a test. if i asked you in a job interview
to tell me about a situation in which you disagreed with how your instructors handled something and you told me about this i would immediately make a connection to patient advocacy and say to you, "as an rn you will be a patient advocate and many times you will need to seek out discussion with doctors or other healthcare professionals with regard to the care your patients are, or are not, getting. how will you handle a doctor who you will need to continually call because he fails to order something for your patients you feel is necessary or writes orders you don't feel are necessary?"
