Correct answer is option C
The instruction the nurse should include in teaching a client with chronic bronchitis about breathing exercise is to exhaled through an open mouth (pursed lips) slowly and gently.
Exhaling through pursed lips help improve exhalation in clients with chronic obstructive lung diseases like chronic bronchitis.
For a client with chronic bronchitis exhalation should be longer than inhalation in order to exhale the air trapped in the airways.
Diaphragmatic breathing is helps strengthen the diaphragm and improve ventilation.
Hope this helps
When you exhale, it should be longer than when you inhale to prevent the collapse of bronchioles. The patient with chronic bronchitis should exhale through pursed lips to extend exhalation, keep the bronchioles from collapsing and avoid air trapping. Diaphragmatic breathing, not chest breathing, increases lung capacity.
In persistent bronchitis, the diaphragm is flat and weak. Diaphragmic breathing helps to strengthen the diaphragm and maximize ventilation. Inspire slowly through the nose and exhale slowly through pursed lips. Deep breath as often as possible.
Use diaphragmatic breathing.-rationale: 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. client needs category: physiological integrity client needs subcategory: reduction of risk potential cognitive level: application reference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing,11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 494.
