Vomiting blood is of concern. Vomiting lots of blood is an emergency.

It's difficult to armchair quarterback this sort of thing but it sounds like she needs to be admitted and managed in the hospital as marked bleeding leads to anemia/and or electrolyte problems which may lead to blood pressure/heart rate/rhythm issues that can be poorly tolerated by elderly folk. Her labs and vital signs will need to kept track of as well as her mentation. Elderly folk can experience changes in mentation that cause all sorts of problems (i.e. disorientation, falls and fractures).

Ask someone to go over the results of her CT scan with you soon. Did the patient ever discuss her wishes for such a situation?

Good luck but this stuff would have me gravely concerned.
