I am a first semester nursing student and in my first clinical. From my understanding "non-pitting" edema was not rated. Is that correct? My instructor has taken points off twice for not rating my "non-pitting" edema. At first I thought she just didn't see the NON part, but when I mentioned it she said that there is 1-4 for non-pitting and 1-4 for pitting. No one I talk to seems to know what she is talking about. I thought the 1-4 stood for how much time it took for the pitting to go away after the skin was pressed on?? I just don't want to keep getting it wrong! Thanks much!!
