Is this medical malpractice?

Ok here is the situation, a 68-year old man with a small history of heart problems comes down with stomach cancer, he fights it for many years, and then one day, the tumor is resisting the chemotherapy to an extent. The doctors treat him with an extremely strong chemotherapy, to the point where his white blood cell count is very dangerously low, the doctors decide to not put him in a sterilized room (a fishbowl), and take little to no precaution as to the weakness of his immune system. The man comes down with a virus, the virus attacks his kidneys, and during the treatment for his virus which had multiple symptoms ( yellow eyes, foul-smelling urine) and was left untouched for a while, the man goes into cardiac arrest 4 times, and the family decides that he cannot take this torture of getting revived anymore, for all his ribs are cracked and he is in chronic pain. The man dies, but this all could have been avoided if he was put into a sterilized room like he obviously needed to be, is this malpractice?(this is a real situation so please no insensitive/mean answers)
