If I were you, I'd ask and let her choose her study whatever she wishes to study rather than blatantly copying the fad of joining "Nursing" course.

In any case, she's not gonna lose anything by joining a course or taking lessons in a field of her choice. Don't worry about cost of joining a degree. I mean, the priciest Nursing/Engineering degree is gonna cost you what? 10 grand for 4 years?
