@cvaughn,
I wish I knew, and I'm sorry your family is going through this. You'll do considerably better at sites that are devoted to just medical care or nursing, such as WebMD, to get a more accurate response. Of course no one who's at all competent and cognizant of medical ethics will provide medical advice over the Internet, but they might be willing to answer the question you're posing re normal procedures.
I'd also advise getting a second opinion - in person - if you are concerned.
