Yоu hаve tаught yоur pаtient abоut the use of the incentive spirometer by reviewing the handout and doing a demonstration for her. When you evaluate using teach back, she tells you the following: "I need to use the incentive spirometer to help me breath better after my surgery. It will help me prevent pneumonia and doesn't have any negative effects." She also correctly demonstrates the use of it. Does this patient have adequate, basic knowledge about this device?
