Wouldn't the correct thing to do in this situation be to immediately inform your doc about his nurse and her "advise and lectures"? First of all she shouldn't be providing any info about anything health related to patients. She doesn't have the knowledge (obviously in this case!) and I'll bet the doc knows nothing about what she's doing. She's there to do the blood pressure etc and get the basic facts for the doc and nothing more. Imagine the harm she could do if someone unknowingly follows her wrong advise about something else ...or imagine how devastating it could be to some new lupus patient, who doesn't know any better, to hear that!!
