Is breathing oxygen good for you?

The correct answer is option A –it helps prevent early air way collapse
The nurse should explain to the client that performing pursed lip breathing prevents early airway collapse.

A client with emphysema is likely to suffer from collapsed airways due to lose of ability of the airways to recoil during exhalation. Pursed lips breathing increases resistance in the airways which helps them stay open during exhalation. This technique is mostly used by people with chronic obstructive lung diseases (COPD).

Pursed lip breathing doesn’t increase inspiratory muscle strength, it doesn’t decrease the use of accessory breathing muscle nor does it prolong the inspiratory phase of respiration.

It helps prevent early airway collapse.-rationale: 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.)client needs category: physiological integrityclient needs subcategory: reduction of risk potentialcognitive level: comprehensionreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 697.
