It's interesting that someone made a thread about this because we had a nurse at our facility before she moved, whom I believed was a "functioning illiterate". Or she had bad eyesight...I'm not sure. She would ask the rest of us to read MD orders for her as well as others' charting, she didn't look at the MAR while passing pills....AM pills had a yellow sticker, Noon: a pale blue sticker, Evening: Brown sticker, and HS meds had a navy blue sticker. I think she just pulled whatever color for whatever time of day it was. Her charting was atrocious; she misspelled easy, common words such as patient, during, and hour. Maybe she was dyslexic, I don't know. It was very strange...
