Where can I find information on culture and medical treatment to educate a nurse who is treating a patient from a different culture?

I'm assuming you mean a culture other than the one the nurse grew up in. I would use the Internet and your local phone book to look for groups who can help educate the nurse. There are many groups for this purpose. Type in "Hispanic culture" or "Bosnian culture" and see what you get. Play around with word combinations. Then, check your phone book. You could even call a local help line to see if they know of a non-profit group to help.

Congratulations for being sensitive to this issue.
