So many things wrong with this picture.
First, OP, you act shocked that the school isn't even accredited, yet you've been there along enough that you are already in clinicals. Did you not do a little homework on potential schools before applying to nursing school? Nursing school is a huge step, a lot of students go through a lot of work to get there, so taking a few minutes to check the school's accredidation and reputation should've been torwards the top of the list when scouting schools. I agree, you are a college student, college students are ADULTS. Some more mature than others, but quite frankly if you are old enough to work towards becoming a nurse where people's lives will be in your hands, then you are old enough to do a little research into the school you plan on attending.
Secondly, your school doesn't have a lab, and y'all were never taught how to do simple vital signs before being thrown into clinical rotations? And then, apparenly vital signs were skipped all together (except for "reading about it over the weekend", which you failed to do anyways) and clinicals skipped straight to GIVING INJECTIONS? Holy canole.
It's scary that a hospital, or any place of health care, is even putting their reputation on the line and allowing this school to conduct clinicals at their facility. Scary indeed.
