How can I keep from losing my savings when my husband will need nursing home care?

You likely can't if this will happen within the next five years. What you need to do is talk with an estate attorney or an elder law attorney as soon as possible, in case there are ways to protect some of your assets.
Take care,

I need more details on your husbands situation before I can comment. I am anxious to hear from you because my spouse is in a Alzheimer's unit and is not doing very well. But I have found some relief.
