Sassy yet sweet, warm yet no-nonsense, Carla is exactly the kind of nurse I'd like to see if I were to wind up in the hospital. She seriously schools the newbie doctors (like her "Bambi," JD, in the early seasons) and is all business with the patients. But underneath the sometimes sharp exterior, there's a wonderfully fun, caring woman in there. Most of all, I love watching the rest of the staff treat her with such reverence and respect. Doctor/nurse hierarchy be damned!
