Need some advice, please

I am new to allnurse.com. I have been lurking for a bit, but I was unsure if I should ever start posting..

Anyways, Here is my dilemma. I have been an LPN for 3 years and every single job I have had I have been terminated. My first Nursing job was in a extended care facility and I liked the Residents and the job itself, but I could not stand the environment in which I worked. I live in the Southeastern US and I am not from the Southeast and I was called a Yankee b**** on more than one occasion and I soon learned pretty much that everyone who worked there was related some way or another. I was terminated for not properly doing a Tx. This facility had a Tx Nurse. I soon realized another nurse on another unit got involved in this and she ended up being responsible for my termination. I was terminated when our DON was out sick. I don't think I would have been terminated if she was there. I had just received my 90 day evaluation and I received higher marks than I thought I would. I was fresh out of Nursing school when I started, so that was job number one.

Job number two was in a outpatient substance abuse clinic and I liked that job, but the owners of the company were minorities and wanted an all minority staff, so I was terminated for a med error I did not do. the other nurse consistently made meds errors and she was not disciplined at all.

My third job was at a SNF and I was pleased that I was hired and loved that job I enjoyed going to work everyday and got along with my co workers very well. I had no problems staying over my shift if needed and I would come in on days off if needed. The TX nurse position became available and I applied for it and received the position. I liked working as a Tx nurse. I thought I was doing an okay job until we got a resident a new geri chair. Everything went downhill from there. This geri chair was supposed to have a pressure reduction cushion built into the chair. Well this resident ended up with a horrible unstagable PU. I had documented that this chair way cause some problems. This resident was in Hospice care for a terminal condition that was getting worse. This resident also acquired Aspiration pneumonia, so this resident's nutritional intake was very poor and thickened liquids had to be given via a syringe. I made sure i documented everything and I kept the DON aware or everything I was doing. I was suspened and then 4 days later I was terminated for poor job performance, I feel totally horrible about this and I have let myself down tremendously. I did not become a nurse to keep messing up. When I was terminated my DON was in tears. I had asked to be put back as a charge Nurse, but my DON said no.

I just want to know how can I overcome this. This really looks horrible on my applications. I just want to know how I can prove to potential employers I am not a horrible nurse and I really do care about my residents and everyone I take care of. I was a CNA for 17 years before I became a nurse. Nursing is all I know! Please help!

Thank you!!!
