I've been ina LTC 32 yrs. 20yrs MDS. I've seen it all! I've had explosions like yours many times. Sometimes nurses are given positions they are not qualified for and don't care to learn how to do it correctly. Then some are just plain in it for the money! It is the hardest job in LTC... If done right it can be rewarding, but you have to have a Team. CYA... Document in a binder (hand written) dates, and times of all conversations, and meetings you have including ones with your DON, and Administrator. If you have a corporate or regional MDS consultant, inform them of your situation. Sounds like she is getting away with doing a substandard job!
