A developmentally disabled patient had about a hundred hard rock-like objects in her Attends which the head nurse claimed were absorbant beads from her Attends. Her family member has legal guardianship of her. Another nurse was discussing this with the guardian who requested a sample of the objects to take to patient's doctor to identify what they were (the head nurse took no samples, only this other nurse, because she didn't believe they were absorbant beads). The other nurse asked if she could call the guardian after the appointment to see what they were. They were not absorbant beads. Since the other nurse called from her home phone does this violate professional boundaries?
