Hi Toni,
I think this would be a great idea! I know often times doctor's offices and staff are so busy it's hard to talk directly to the nurse until the end of day. I know a lot of people dont understand the information the nurse/doctor gives to them in the office. You could probably target the elderly as well. Since you are a nurse you are already knowledgeable in the medical field. This is a super idea and I think you should go for it. Another thought, since diabetes, heart disease and other chronic diseases are on the "rise."
Example:People have a hard time managing their diabetes, you could help them understand how to do this. Good Luck to you.
