Letter from the Board of Nursing.

I could use some advice. I worked for this family as a pediatric home health nurse for over a year. I ended up leaving when the mother became irate at me over a suction catheter that went missing, getting right in my face and began spitting as she was shouting at me. She then threw a ben of suction catheters on the floor and left them for me to pick up. I finished my shift, charted the altercation in my narrative and informed my supervisor the following morning that I would not be back. This was on a Friday. I got a call on Monday and was accused of showing up late to work, but clocking in on time. The system automatically clocks you in at what time you're supposed to be there, so we're talking about maybe minutes. Over the course of a year, this amounted to about $140 and did not give credit to the times I showed up a few minutes early or stayed a few minutes late. I admitted to the mistake and paid the time I was overpaid back and thought I was done with it. I've since quit the company and moved on to hospice nursing. This was back in June and I just received a letter from the board of nursing essentially accusing me of stealing company time and being unethical and they're asking for a response in 30 days. I'm pretty devastated. Has anyone been through this? What can I expect? Any advice on attorneys?
