I am 2 days late. I hope by now you have taken your mother to a doctor and she is alright. The thing about such high blood sugars in a type 2 is that they go for something called HONK which could be quite a dangerous situation. It's best attended urgently.

Hi there...I can understand your concern. It is better to take to a general physician or diabetician as soon as possible. Sometimes due to very high sugars, the patient can develop complications like diabetic keto acidosis. Also she will need to get her HbA1C and urine routine for ketone bodies. But first take her to a general physician in the morning for further evaluation.
