She seems like she has no regard of your time, her time matters more.
I encounter people like that at work, too, the ones who will come in to the patient's room from behind the curtain when they hear me talk, and start talking about things unrelated to this patient. Doctors, social workers, registration, etc.
One registration lady interrupted the med pass (door was closed), I literally was spoon feeding pills with apple sauce. She came in, and proceeded to talk to the patient about Medicare form, and then asked me : " Are you finished with the patient yet?" I politely asked her to wait until we finish, so she did, tapping her foot. In the hallway she made a remark about how I am here all day, and she is not, so I should have let her have some time with the patient right there. Again, her time is more important, I guess.
Keep the educator in line by asking to not discuss non-patient matters in a patient room.
