Hi Diana. Welcome to Allnurses.
At this point you should be able to do those things. You need to start asking to be a part of those things. Next time you work, speak to the charge nurse and say "if a code comes in, I want to run it", etc. You have to jump right in and do it yourself, rather than wait to be asked.
The orientation here is different. Before a person can be off of orientation, they have to do so many traumas, so many chest pains, so many CVA, and so many codes, etc. In fact the old folks complain that the newbies get to have all the fun.
Good luck. Welcome!
