Congrats on your new job. Every facility is going to have different policies and different populations (i.e. more dementia, more rehab pts, etc). I would try to find out what types of patients you will be dealing with and try to focus your review in those specific issues.
Of course a general review of anything you had issues with in school would be beneficial. But to be fair, I don't feel like nursing programs
fully prepare anyone for the reality of dealing with their first job. You will have more patients and most likely will have to supervise CNAs.
A few tips: trust your instincts. I had issues with that as a new nurse. Just because a nurse has more experience than you doesn't mean they're always right. If you think something is wrong with a patient, do what your instincts tell you, regardless of whether a more experienced nurse says they're fine.
Take advantage of your orientation. If you see a med or treatment you're not familiar with, research it so you won't be flying blind once you're on your own.
Get to know your staff. Who are the people who have been there a long time? Who is reliable to help you with tasks? Who is willing to answer any question you might have?
Mostly, know you will be slower when you first start. Your meds may be a little late. You may see nurses running circles around you. That's ok because when you're first beginning, you need to take your time so you don't make mistakes. It will take time to get up to speed. Don't get discouraged that you can't keep up. You will catch up in time. Just concentrate on the fact that you are still learning and you are making sure you do your job correctly.
