A home care nurse visits a client who is confined to bed and is cared for by her daughter. The daughter is known to suffer from chemical dependence. The home is cluttered and unclean. During the assessment the nurse notes that the client is wet with urine and has dried feces on her buttocks, and demonstrates signs of dehydration. After caring for the client, the nurse contacts the physician and reports the incident to Adult Protective Services. This is an example of which ethical framework?
