If I were you I would withdrawal from the course if you can. Your GPA is very important for nursing school. Im not sure about your program but where I live they factor everything in. I understand where your coming from. I was a double major in Spanish and nursing and one class I got a C not to bad but not the best either. I was able to keep my other grades up so it really didn't affect it but if I was concerned about it I would have withdrawal because that can save your GPA. Just don't get in the habit of withdrawal. Just my opinion.
