Can't or Won't

I just returned from the hospital about an hour ago and have been processing what just happened. I was called to the hospital to baptize a 22 week premature baby - nothing out of the ordinary. Fortunately the baby was alive and I was able to perform the Sacrament of Baptism, thanks be to God. But what I found strange is that no medical personnel were tending to the baby. The mother was simply holding the baby, apparently awaiting an imminent demise. After completing the Sacrament and talking with the family I went back out to the nurses station. I mentioned to them that I knew personally of a baby born at 20 weeks that had survived and asked why nothing was being done to help this baby. There were many nurses there and they all immediately fell silent, as if they were not supposed to comment on such things. One of them said I should ask the doctor in charge. Upon relating to the doctor what I had asked the nurses I was presented with a look. Her demeanor seemed to say that she did not like to have her decision questioned in the least. And she said to me in what seemed a very condescending tone, "The baby is only 22 weeks. There is nothing we can do." But I wonder, is there nothing she could do or just nothing she was willing to do. There is a big difference between the two.
