Passing the buck?

At first I overlooked it...but after 2 years of this....I'm steaming mad, psychotic is how my close co-workers describe it but either way...
I'm the MDS Coordinator for our facility. I do NOT understand this building. Everytime someone slacks off on their job, it ends up being my job to do. Every time someone "doesnt have time", it ends up being my job. Examples: A resident is admitted to the facility. The nurses on the floor dont acknowledge she has a skin issue going on. They dont chart it, start a treatment, or pass it in report. Needless to say it was horrible by the time whoever found it and reported it. This had happened over and over. So the answer to fix it is.........ding ding...you guessed it, the MDS nurses will now do skin rounds with the floor nurse every monday, initiate treatments, and perform measurments. Also on that line....MDS nurse will look thru all new admission charts the morning after admission to check and see if the nurse who did the admit, followed thru with skin protocol. If not MDS will initiate it themselves.
That happened months ago, this week. I was personally invited to the administrators office, where she and the DON asked if I could do the sections on the MDS that social services and activities normally do. Well of course I can! Do I want to? Do I have time? NNOOOOOOOOOOOOOOOO!!!!! But then...they dont have time and they cant keep up. Now I find out, I'm also to do their careplans, and give them my notes to write their progress notes by. I have held my temper until today.............the activities director comes to me, with a smirk on her face I might add, and gives me some detailed worksheet she says she has to fill out with every assessment....and whats more, she says i have to use the activities I "see" the resident have.I dont see most of this. She doesnt have it all logged she says, she just uses what staff sees plus the activities on her calendar. Needless to say, my assessments and hers look nothing alike! She thinks we can adjust that if she "helps me out a little"
OK, now that I have that off my chest......Does anyone else have things like this happen? or am I the lucky one? I'm taking it to the coorporate nurse and administrator tomorrow. Arent staff members to be held accountable for their own work any more? Will I have a job when I do? Not sure I even care at this point. Interdisciplinary...what does that mean?
