It's a baby....(Scary and weird)

So went to the hospital a few weeks ago. The nurse was kind of rude in some aspects and cool to deal with in others. The reason I say that is because I get into the room and she doesn't hook me up to the monitor(Which is fine) she just listens to my baby move and goes on to say: We don't hook the monitor on you and leave it because here (Local hospital) we have a policy to not resuscitate before 24 weeks. Kind of pissed me off and scared me at the same time. Has anyone heard of this and why is it so???
