A nurse is caring for a patient admitted for management of a femoral fracture. The healthcare provider enters the room and begins asking the patient about his level of pain. The nurse answers that the patient has no pain as he was just given pain medication. The healthcare provider then asks the patient if the patient has thought about whether bracing or physical therapy would be his preferred method of treatment following fracture stabilization. The nurse answers again that the patient would prefer physical therapy. The nurse is violating which ethical principle?
