Eh, it's been my experience that medical professionals stand in the extremes on health-related issues. They either smoke two packs a day or would hurt you for picking up a cigarette near them. They either eat their weight in steak or eat their weight in vegetables. And others.
They also have a greater knowledge of human anatomy.
Assuming your nurse stands on the correct side of the line in the "healthy lifestyle" department, go for it.

If she doesn't, count it as doomed and get goin'.
