A 65-year-old patient is admitted to the hospital with heart failure. The patient's best friend accompanies her on admission. They have been sharing a home since they each were widowed 3 years ago. Both women have grown children who live out of state.
 
  Using the family nursing approach, how can the nurse best intervene?
 
  1) Involve the friend and children in the patient's care, discharge planning, and home care.
  2) Encourage the friend to wait until discharge to provide care for the patient at home.
  3) Explain to the friend that for confidentiality reasons she cannot be involved in the patient's care.
  4) Encourage liberal visiting hours by the friend and the patient's children.
