silly question, can LPN's teach?

I am a new LPN and am a little confused on weither or not LPN's can teach. I have to do admitts and d/c at my SNF and want to make sure this is ok under my scope of practice (Oregon). My NPA (Nurse Practice Act) says "provide, under the direction of a RN, health care clients using established protocols, can someone disect this please! I am so nervous my facility is asking me to do things beyond my scope because I am so new I just don't know(first LPN job, start in a few days). I have so many questions, is it ok to call the Dr. intead of the RN like my facilities policy and procedure says when my NPA says collect data and in a timely mannor report it to a RN, ofcoarse it also says communicate nursing interventions and responses to care to the appropriate members of the health care team. And develop work assignments, Is all this OK??? I am scared out of my wits and tend to phych myself out (as in right now) Does this all sound corect, will I stay with-in my scope doing admitt's, D/C's, (ie, teaching), Calling Dr.s instead of RN, and making assignments? I am sorry, I just need some support, I am so nervous and have worked so hard..as all of you know. I just want to do the right things. Please help!
