New RN Job Probation Period:

Hi, I am a new RN and I am starting my first RN job very soon. People keep telling me that in every hospital there is a probation period, meaning if they don't like your work after X amount of days, they let you go..... Is this something I should be worried about? I am already anxious and nervous about my first day as a brand new RN, and I haven't done nursing skills in months and months. Does anyone know people who have been hacked by not being sharp or quick enough at the job?? I mean, what are the standards exactly? I hope they don't expect new RNs to just know as much as experienced nurses.....Any advise is helpful and very much needed! Thanks.
Don't obsess on the possibility of being terminated. Instead, focus your energy on learning to do your new job.Make sure you are provided with very clear information about what it takes to be "successful" in orientation. What are you expected to accomplish, and what are the time frames. What criteria are used to evaluate the goals? There should be policies and procedures that outline all of the clinical skills you are expected to learn. Try to schedule regular feedback sessions with your manager &/or preceptor so you will know how you are doing. Relax & continue to do your best.
Thanks for the awesome advise! I start next week.
