Any input is appreciated!

So my SIL is 29 weeks she said her BP was 180/120 blood sugar 411 and her doctor said her kidneys are only functioning 20%. They are not keeping her in the hospital to monitor her or anything just told her to continue with blood pressure medication and insulin, my question is all of that together is pretty severe why would they not take the baby? I understand 29 weeks is still very early but to keep putting their bodies through this and not even monitor them besides weekly checkups seems strange to me. Anyone have any input or dealt with similar issues and can give some insight?
