Refusal of Blood

Hi...Still a new nurse under a year. Finally experience my 1st patient who refused to have a blood transufion even though her H/H came back with panic levels. Because of her refusal, the doctors are basically treating her with iron and oxygen. I did give one dose of Procrit 10,000 units sq. The family has threatened to call the head of the hospital, etc. because they feel that the docotors aren't doing enough. The hematologist is the one that ordered the iron and oxygen, and stated it would be a long process before her H/H would come up. What more can be done? Thanks...everyday is a learning experience.
