Yikes everything I have ever hated about nursing is in this thread. So I will offer tips that have worked for me to make it better.
1. Go faster. Seriously. Find ways to do things faster.
2. Anything they don't complain to you about later when you don't chart it is something you don't need to chart. I can't count the amount of times I was told that I should chart such and such by one nurse, and then told something different by another. Eventually you will figure out which nurse is more reliable, but for now, just drop any charting that there is a disagreement on.
3. Change units. Follow the money/glory. If you hospital is super proud of a certain unit it's gonna be better because they care about it. Also if the unit spends a lot of time with money bringing physicians (like OR or Endo) it will be better.
4. Don't complain. Hospitals are the feeding grounds for complaints. Negativity is bad for you, avoid it. If you have a suggestion for an improvement that cost nothing then you can say it. Otherwise no good comes from anything you comment on.
5. Upgrade and run. The great thing about nursing is that it has lots of ways to trap you deeper in the rabbit hole. Popular options are:
*management - now you get to be who you probably haven't liked at some point. Pick the unit carefully on this one as being a regular floor manager may pay alright, but it generally sucks. Try one of the specialty units. Surgery/ER management seem to be prerequisites of becoming real big wigs.
* FNP - the easiest option. You can work while you goto school. And then you can graduate and keep working on the floor when you can't get a job!

Which has a decent probability of happening. Google Nurse practitioner can't find job. You will see why FNP is becoming as saturated as regular nursing. (obviously I am not to high on this one, but if you already know a doc who liked you and will hook you up with a job, then it's fine.)
*CRNA - the golden bullet. This is the favorite. But be ready to jump thru hoops to get in ('ICU level exp'/the dreaded GRE, lol). And then get ready for 40-50% of your class to fail after the first year (tuition is front loaded). Once you get out the situation may still be a problem. You still might have to take a job at a worse group to get exP, and while not near as saturated as FNP, CRNA is slowly working itself upto saturation levels.
So there. All your nursing options in one post. Next time someone looks up 'I hate nursing' they will get all the wisdom I can offer.
Although I like my current job I am very excited to be starting medical school in a month. I get to see a alot of medical/PA students at work. Their 'suffering' in clinical's is no where near what a new nurse would go thru on the floor with a malignant preceptor. Intern year I could agree with, but as a student? Just completely different, that student coat gives you a ton of protection that an 'employee' doesn't have.
