I am a nurse in a long term/post op rehab facility. I have been a nurse 3.5 years and this is my second facility. I have worked short/under staffed (as in accordance to state regulations I am referring to) many times of course, it comes with this field. But the last couple weeks at my current job has gotten really bad. I currently don't remember the last shift I was fully covered with CNAs. I am currently working NOCs because we were short nurses. They have me doing 5 12s with 2 days off. From 2-10pm we are suppose to have a med aid for 2 hours and 4 CNAs with our current census. Tonight we had a med aid and 3 aids until 8pm then only 2 aids. My next shift there is 1 med aid, 1 CNA, and a light duty CNA for staffing. I am getting really tired of lack of staff. I have no idea how this is suppose to work. My main question now is coming down to how much of my own license am I risking every time we are running short and at what point am I being neglectful if I don't turn the facility into state (or whoever is above the company)? I have tried to talk to my DNS and director.. all they can say is they have tried... please- any advice will help.
