I think she's referring to the things that are inherent to all nurses. Common sense/critical thinking, compassion, being able to see the big picture. If you took a cross section of nurses and placed them at a level that all the nurses SOP covered you'd probably get the same results.
That's what most of the LPN vs RN's miss. I can do MY job as well as an RN can. I'm not saying that I can do her job but if she were to do mine it would be about the same.
