I just started my first LPN job about 2 weeks ago. There is nothing you can "prepare" for. I have wonderful, experienced co workers that are SO VERY helpful...you won't get that lucky sometimes. All I can tell you is to ASK ASK ASK. The hardest part of the job is to remember how to get on the computer, or which pharmacy to fax, or which doctor to call at what times of the day (the doctors that the residents have at this place are NUTS)...Its stuff like that that is hard. I trained 4 days on one cart, had one day alone, then will do that process again with all 5 carts until I get through them all. Everything is a "find out one the job" type thing. Most facilities have their own protocols on how they will do things. You will have tons of questions...and they are going to expect that. I get a lot of help from the residents...they tell me "hey, so and so Is starting to act goofy...you may want to watch her."
You will do great...its a lot to take in though...but you will for sure learn sooo much.
The HARDEST part is learning the names and faces!!!
Good luck to you!!
