Very few people in distress can coherently answer an open-ended question such as "what can we do for you?" It also puts her in a position of, basically, asking a favor, and this is not something that a hurt person would be inclined to do.

Give her a list of specific things you can do. Or rather just do them first, and then tell her. Rent and furnish an apartment for her and bring her the keys, for example. That will go a much further way than just writing a blank cheque.
