nursedes

I just started working as an LPN 3 months ago...I worked as a CNA for 5 years. I work at a wonderful geriatric facility. I am 24 and I am very passionate about my job, and I genuinely care about my patients and I also care about being a role model for others when caring for the elderly. My problem is that my CNA's are not working with me. I work 7-3 and have 26 patients, and as all nurses know there are treatments, paperwork, MEDS, families, as well as interacting with dietary, PT, OT, and many others...so much to do... My CNA's complain constantly....are loud, laugh, carry on...when in the dining room at meal, residents are ignored, yes they try to spoon food into their mouths but they don't talk with them, they talk loudly and laugh loudly with their co-workers...when I ask, and ask politely and many times offer my help to put a pt on the toilet or to put them to bed they don't do it at all and I end up doing it, or they roll their eyes....when I do something to try and help them out such as get more help when we are short, I get yelled at in front of residents that they don't need help and I did the wrong thing. I am talked about behind my back, they whisper and huddle in corners and I have heard they say I am too uptight for a 24 year old. I have spoke with other nurses and they have said that this has been a problem on my unit before and that other aides dont want to work there because of the aides that work there now. I am a kind, fun, and outgoing person....I am affectionate with my residents and I am hard working...I just want to see that they are taken care of well....how do I handle this, and what am I doing wrong? Please help
