The nurse in charge is teaching a client with emphysema how to perform pursed-lip breathing.. It helps prevent early airway collapse



The nurse in charge is teaching a client with emphysema how to perform pursed-lip breathing.
The client asks the nurse to explain the purpose of this breathing technique.
Which explanation should the nurse provide?

a- It helps prevent early airway collapse.

b- It increases inspiratory muscle strength.

c- It decreases use of accessory breathing muscles.

d- It prolongs the inspiratory phase of respiration.

Answer A.
Pursed-lip breathing helps prevent early airway collapse.
Learning this technique helps the client control respiration during periods of excitement, anxiety, exercise, and respiratory distress.
To increase inspiratory muscle strength and endurance, the client may need to learn inspiratory resistive breathing.
To decrease accessory muscle use and thus reduce the work of breathing, the client may need to learn diaphragmatic (abdominal) breathing.
In pursed-lip breathing, the client mimics a normal inspiratory-expiratory (I:E) ratio of 1:2. (A client with emphysema may have an I:E ratio as high as 1:4.)
