Nursing jobs require not only treating patients who are sick and injured, but also offering advice and emotional support to patients and their families, taking care of paperwork (lots and lots of paperwork), helping doctors diagnose patients and providing advice and follow-up care.
That's right, there's a lot more to nursing than meets the eye. It's one of the hardest and most emotionally draining jobs out there, but it can be incredibly rewarding. There aren't many jobs out there were you can actually save someone's life, but this is one of them. Got a weak stomach? Then consider a different career, my friend. Working as a nurse means having to deal with terribly sick people - and that often involves various bodily fluids (yuck).
