No research hours

I’m a non-traditional pre-med. I am going to college right now. I am working full-time along with full-time school and family responsibilities. I don’t have any research hours. I don’t know who to ask how will medical School admission committee look at no research hours. I have a lot of healthcare experience including patient care, volunteering and shadowing but no research hours. As a non-traditional student who has been out of the school for a long long time and a full-time working mother I don’t know how to apply or get research projects that might look good on my application. Anyone can help?
