Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The primary purpose of pursed-lip breathing is to:
A
Promote oxygen intake.
B
Strengthen the diaphragm
C
Strengthen the intercostal muscles
D
Promote carbon dioxide elimination
Explanation: 

Detailed explanation-1: -The positive pressure created opposes the forces exerted on the airways from the flow of exhalation. As a result, pursed-lip breathing helps support breathing by the opening of the airways during exhalation and increasing excretion of volatile acids in the form of carbon dioxide preventing or relieving hypercapnia.

Detailed explanation-2: -Pursed lip breathing is a technique that helps people living with asthma or COPD when they experience shortness of breath. Pursed lip breathing helps control shortness of breath, and provides a quick and easy way to slow your pace of breathing, making each breath more effective.

Detailed explanation-3: -Pursed lip breathing works by moving oxygen into your lungs and carbon dioxide out of your lungs. This technique helps to keep airways open longer so that you can remove the air that is trapped in your lungs by slowing down your breathing rate and relieving shortness of breath.

Detailed explanation-4: -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? It prolongs the inspiratory phase of respiration.

Detailed explanation-5: -Rationale: Pursed-lip breathing facilitates maximal expiration for clients with obstructive lung disease. This type of breathing allows better expiration by increasing airway pressure that keeps air passages open during exhalation.
