Is it normal to be scared out of my mind ?
Sure! You are entering a whole new world, you don't know the unit culture, you don't know who your friends are (or arent!) and you are not familiar with any of the paperwork etc. If you weren't scared, then you should be worried.
Do the preceptors expect a lot from you?
Depends on the preceptor. I have been working with several. Some insist on following me around and checking all my charting and telling me what to do, others say "come and get me when you need me" so it really depends on the person precepting you. One would hope you come with basic nursing knowledge/skills relevant to your specialty but I have found on a whole, nursing instructors are more demanding than coworkers are. something to remember tho, everyone thinks their way is best. So you will be exposed to lots of people saying "Well, I do it this way" and whatever 'it' is, you will be expected to do it that way while you work with that specific person. Just do it and learn. You will find your own way that works best for you as well.
How did you feel, and when did you get comfortable?
Well, I got comfortable last night lol. Seriously. We were short two nurses, my preceptor got grand jury duty for a few weeks and so I was given 3 mother/baby couplets and an antepartum and told to ask anyone for help if I needed it. This was probably my 5th or 6th time working with mother/baby patients. (I did a week or so in NBN first, and before that was 2 weeks of classroom) I was nervous and the charge really made sure I felt capable. Nervous and capable are not mutually exclusive, I learned. My patients survived me, and I survived them!
Any advice...
Well, wear comfy shoes, bring an extra pen, keep at least one powerbar in your locker and have some gum or breathmints. And eat before you go to work even if you're not hungry.
Seriously tho, just go with the open mind that you had in school, and realize that every single nurse you are working with was a new nurse once as well. Be friendly to everyone and confide in no-one, and make friends with the techs! It is a HUGE team effort between techs and nurses and when you all get along, everyone is happy.
Oh, and make up an assignment sheet that works for you.
Good luck! It looks like you started this week!
