Nursing
Medicine
There is not one single shared course between the two degrees. If you can find a course shared between medical and nursing students in all of Europe I'd be surprised.
Nursing is taught at many universities with medical degree, first and second year students tend to share some of the lectures.
Also, because of that, people with nursing degree are able to acquire a medical degree by taking the extra lectures and exams afterwards.
It is not examples that one finds online, rather on corridors and schedule notes.
What I can provide as an example is that nurses and doctors have equal access to many master and PhDs. Check "condições de acesso" in some of the links from the page and you will find "enfermagem" as accepted degree.
