Not only do you want a nursing home to care for your loved one's current condition, you also want to make sure that they do all they can to keep the resident's health from declining. So ask about their preventative care programs. Do they offer nutritionally rich meals? Are residents encouraged to exercise? Is there a program for flu and pneumonia vaccinations?
Something else you'll want to investigate is what steps the nursing home takes to keep residents' minds healthy, as well. Are there group chat sessions? Regular visits by a social worker? Are brain-building or memory-testing games available? A stay in a nursing home does not need to lead to an inevitable decline in health. With the right focus from the facility, patients can sometimes even improve their overall condition.
