We have developed a flow sheet which includes all 3 shifts. It has the various cares listed for the CNA's to initial. That is if they gave a partical bath, nail care etc. they initial the flow sheet. The flow sheet also includes an area where they initial and sign their name, just like med sheets have. When our CNA's are given their assignmnets they are also required to sign the flow sheets to indicate the care they have given. However, if you are the charge nurse, under law, you are responsible for the care delivered to your patients. This is not an easy assignment, but with the flow sheets, CNA's are less likely to say(sign) that they did something they didn't. If a patient complains about something it is much easier to track who was the caregiver and check into problems. You sound as though you need an administration who will also back you up and help you establish authority lines. If you boss is not willing to impower you, than you will have very little control. If this is the case, I would look somewhere else for employment.
