Much needed Advice please

Today I had my midterm for my Comprehensive course. It covered the function of the reproductive system, complications that could occur, assessments, interventions, and evaluations of those complications. The textbook that the reading came from is not a very good one, according to multiple instructors at the school but they continue to use it because they already told everyone to purchase it and made their lesson plans from it. They are in transition to changing to a new textbook and are implementing this change with the upcoming semesters.

Now the exam was difficult....very difficult. I did my best and was able to work through about 70% of the questions. However, there were many questions that included terminology, procedures, interventions to implement, medications, and other things that I cannot remember, that I do not remember reading in the textbook. I even referred to my textbook (which I had brought with me....I know insane because its like 1000 lbs!) as soon as i came out of the exam to see if I missed reading it in the textbook but i still couldn't find it in the textbook.

Example: One question asked, "What sign would indicate to the nurse that cervical cancer has metastasized in a patient? Choices: Amenorrhea, swollen leg, breast tenderness, and another choice i can't remember. I honestly did not know what to choose and guessed amenorrhea because it was closely related to the reproductive system.

I tried looking in the textbook for the answer but it never even mentioned what to look for to assess if/when cervical cancer metastasizes. Of-course many people were outraged at the exam, stating it was unfair. I appreciated the difficulty of the exam but was upset at how unprepared I felt. Multiple people expressed their anger to the instructor regarding the exam and stated that there was content on it that was never covered. Instead of being angry at the instructor I was hard on myself for not doing everything needed to be prepared for the exam. I asked the professor if there were any other resources that should have been used in order to prepare for the midterm. I assume she was already flustered and she thought I was ready to blame her for my possible failure and became very defensive stating that everything on the exam came out of the textbook we were asked to read and that if we were unfamiliar with anything its because we didn't read and didn't take the exam seriously.

Still trying to explain what I meant using the example of the cervical cancer question, she raised her voice and stated, "I'm not discussing the exam!"

I don't expect to be spoon fed information and know that there is a lot of reading that goes along with these courses. However, if what I am asked to read does not include certain things than how am I supposed to know them. Should I automatically use multiple resources when preparing for exams even though professors haven't stated to use anything else? Was the question I brought up earlier something that needed more critical thinking than I thought and was not supposed to be clearly stated in the textbook? I feel as if the instructor may be also using the "new" textbook that the school will be transitioning too but she denies using any other textbook or resource.

Any advice given will be well received and appreciated. Sorry for my long story.
