Where can I find info on how to choose a home care nurse for an elderly person?

You may compare nursing homes on the website, http://www.medicare.gov/NHCompare/Include/DataSection/Questions/SearchCriteriaNEW.asp?version=default&browser=Firefox|3.5|WinXP&language=English&defaultstatus=0&pagelist=Home&CookiesEnabledStatus=True . It is a government website, so it is very dependable and useful.
