CNA and Vetpro hiring process for VA Hospital

I have several questions regarding the VETPRO process for a Certified Nursing Assistant. I recently interviewed with a VA hospital for a CNA role. So far, I have completed the panel interview. There were 4 people taking turns with questions. The day after the panel interview, I received a telephone call from a nursing recruiter. He wanted the phone numbers for 4 co-worker references. I provided this information but the references I supplied were for office work and not previous nursing roles.
Will this matter? I assume he hasn't made the calls yet since this was yesterday.
Now, here is my problem. I have read some of the problems with filling out and waiting for the VetPro background check. I am 40 years old and haven't worked as a CNA for several years. I am currently in a customer service role. But I have kept my CNA and CPR certification current. I have kept it current by being a live in aide for a family member.
It has been around 10 years since I last worked as a full time CNA.
I don't remember co-workers names and can barely remember supervisor names.
I also worked for a lot of different nurse staffing agencies. I can't possibly remember my dates of employment and may even have a problem recalling all of the staffing agencies.

Is the Vetpro process the same for a CNA as it is for a Nurse?
Can I use my family member patient as a reference?
Do I have to give exact dates of employment? If I give a ballpark date, will this hurt my chances?
What if there is no record of employment?
What if the company has closed?
What if I can't find an old nursing co-worker to use as a reference?

Can anyone please shed some light on the hiring process for a CNA? Is it as strict as it is for the nurses? I really would love this opportunity but the whole VETPRO process has me worried.
