Explaining a gap after caregiving or layoff after 5 years as a nurse's aide

My résumé shows a gap from a layoff and some health issues. I am in Salt Lake City, in case local advice matters. I am nervous about being filtered out. What do you say in interviews?

Thanks for writing this out. I went through something close to it 10 months ago, and it got easier once I kept a simple log of every call and form.
