I am sorry you got stuck with such a lousy professor. You can complain to administration all you want after the class is over, but it looks like you're stuck with her for now. Don't waste your limited study time complaining about the professor, because things probably won't change this semester. Use that time to absorb as much material as possible. Try going to this professor's office hours to see if she might be willing to help you after you specifically ask for her help. Set up a study group with your other students, and try your best to teach each other the material. If there is another professor, ask that one for help. I know it's not the answer you want to hear, but that's the way it is. Nursing school isn't just about being taught, it's about learning how to learn, and in some cases, how to teach yourself something.
Please don't take this as me being mean; I have a professor who is like that this semester. Heck, we would be lucky if she lectured to us, but it is an online class, and she doesn't. Study groups are how we are teaching ourselves these things, and how we are coping with this class. I'm also a first semester student, so I'm just dealing with it as it comes and plotting my revenge via my course evaluation.
Best of luck to you, keep your chin up, and ask for help from your classmates. Maybe even somebody in one of the upper classes might be able to help you.
