depending on how the forces of the living (
) react to such a situation i think that you could remain there for a good while, providing that the
room is solid (not dry wall and a lockable door(s). i dont think that such a situation would remain a threat for any extended period of time (within the week before some kind of method is enacted to rectify the problem).
what is the situation with people dying? is it classic "anyone dead comes alive" or a 28 days later virus kind of scenario?
if it is the latter, i wouldnt attempt any form of physical defense unless absolutely necessary, and only with a decent weapon of some kind (which you must arm your self with ASAP).
eventually i think some kind of armed forces will arrive (extermination squads armed with napalm weapons and gas), in which case im not sure if it is a "kill anything that moves inside" precautionary method, in which case you are pretty much screwed unless you show clear indication you are not infected, dead or whatever the case may be.
with water and food, i would say that these are not a problem. you are in a hospital so water should be plentyful (in either filters which in a hospital i think that there is a lot of, or through stored bottles, for the filters, or direct running water which should be operational unless there has been a fire or explosions).
food souldnt be an issue. you wont die of hunger. there will be vending machines around. besides you wont be up there long enough, you will die of sleep deprivation before starvation.
to sum it up: just stay put and lock all the doors. wait for the guys with the guns to sort it all out, you dont really have many other options.
