Alleged unprofessional conduct

Hello all;

I am an LPN @ a LTC facility. My DON is currently unavailable to answer my concerns. I recently recieved notice from the Disciplanary Dept. of the State Board of Practical Nurse Examiners. It appears that I have been accused of allowing a patient to eat a meal in his room when orders where to have all meals in dining room. This supposedly occured in April of 2007. My question is: What documentation should I provide to the Board to answer these charges? I have only a few days remaining to submit information or documents to show that I have not violated any law and/or rule. Thank you in advance for any information you provide.
