Patricia,
I agree -- there should be someone available who can discuss those matters with the student. You just want to make sure that whoever takes on that responsibility is talking about opportunities and not limitations. It is easy for folks to share information with students (based on their personal experience in an area) that comes across as restrictive because it leaves the student feeling that they must refocus their goals. While sometimes that might be appropriate, we need to be careful not to let such conversations hinge on TRADITIONAL positions and skills, instead of focusing on future opportunities.
