Can your nursing license be revoked due to a breach of non-compete/ non-solicitation clause?

I am a Licensed Practical Nurse doing in-home nursing for an agency. When hired, I was told about a clause in which you could not work for a client for six months after leaving the company, otherwise you would face a $10,000 fine. I have been with the same family for a year and they have been dis-satisfied with the nurses provided by said company. I have a feeling they will leave this company soon, tension is high daily. So, I called the company to get clarification on the clause a.) does the $10,000 apply to the case as a whole or will I be fined for each patient at this home? b.) does the family get fined, or is it the nurse, or both parties?
The response was very vague and gaurded and in a nut-shell, I was told that the family would be fined, then it changed to both parties would be fined, then I was told there was no time parameters for the clause and if I ever worked for the family they would submit my license to the board of nursing and I may lose my license. Am I allowed to have a copy of the agreement? I feel like they are trying to use scare tactics to co-erce my decision. If the clause states six months, can they really go after my nursing license?
