question 18 of 20
a nurse is caring for a client with copd. while reviewing breathing exercises, the nurse instructs the client to breathe in slowly through the nose, taking in a normal breath. then the nurse asks the client to pucker their lips as if preparing to whistle. finally, the client is told to exhale slowly and gently through the puckered lips. the nurse teaches the client this breathing exercise to accomplish which goals? select all that apply.
strengthen the diaphragm
prevent airway collapse
release air trapped in the lungs
condition the inspiratory muscles
control the rate and depth of respirations

Explanation:

1. Prevent airway collapse: Pursed - lip breathing (the exercise described) creates a back - pressure in the airways during exhalation, which helps keep the airways open and prevents their collapse.
2. Release air trapped in the lungs: The slow and gentle exhalation through pursed lips allows for more complete emptying of the lungs, helping to release the trapped air, which is beneficial for clients with COPD who often have air trapping.
3. Control the rate and depth of respirations: By focusing on the slow inhalation and exhalation process, the client can better regulate how fast and how deeply they breathe.

• Strengthen the diaphragm: Pursed - lip breathing is not primarily for strengthening the diaphragm; diaphragmatic breathing is more associated with diaphragm strengthening.
• Condition the inspiratory muscles: This exercise is more about exhalation and airway management rather than conditioning the muscles used for inhalation.

Answer:

B. Prevent airway collapse
C. Release air trapped in the lungs
E. Control the rate and depth of respirations
