案例分析题Mrs. Harris, an elderly patient in a nursing home, sat all day in a chair. She did nothing else. She required complete physical care, even feeding. No one seemed to realize that she was partially deaf and blind. One day, a young doctor observed cataracts in both her eyes. He discovered that if he spoke in her ear, she seemed to respond. One eye was operated on, and when it was first uncovered, the old woman cried with joy. Her recovery was quick, and she soon became quite independent. She started feeding herself and took to smiling and talking with others. The change in her attitude was amazing. Not only did she require less nursing care, but she was also able to help other patients. She was again able to see and with this, seemed to experience some hearing recovery.
