The nurse is teaching a male client with chronic bronchitis about breathing exercises. Which of the following should the nurse include in the teaching?

Use diaphragmatic breathing.

In chronic bronchitis the diaphragm is flat and weak. Diaphragmatic breathing helps to strengthen the diaphragm and maximizes ventilation. Exhalation should be longer than inhalation to prevent collapse of the bronchioles. The client with chronic bronchitis should exhale through pursed lips to prolong exhalation. keep the bronchioles from collapsing. and prevent air trapping. Diaphragmatic breathing not chest breathing increases lung expansion.
