If watching "Grey's Anatomy" has you convinced that doctors make all the tough decisions and are always there to welcome a new life or walk a patient to the grave, you're only half right. As one nurse noted, most of the stuff you see a doctor doing on "Grey's Anatomy" is actually what nurses do in real life. And what's more, nurses aren't dumber versions of doctors.

Nurses are as valuable as doctors simply by virtue of how much time they spend with a floor of patients. When something goes wrong, odds are a nurse is going to be the first to handle it.
