Medical Surgical COPD #6
The nurse is preparing instruction for a client with chronic obstructive pulmonary disease (COPD). Which demonstration by the client will be mastered for pursed-lip breathing technique?
- The client will take a deep breath with lips pursed then exhale fully with mouth open.
This answer is not correct because this return demonstration would require further instruction from the nurse. This is not the proper method for pursed-lip breathing.
- The client will breathe in longer than breathing out.
This answer is not correct because this return demonstration would require that the nurse further educate the client on the proper technique for pursed-lip breathing. While exhalation does take longer than inhalation with pursed-lip breathing, there are other key components to the technique that are not included.
- The client will inhale with mouth closed, purse lips and exhale while counting to four.
This answer is correct because pursed-lip breathing includes inhaling with a closed mouth slowly (two counts), then pucker or purse lips as if whistling or flickering a candle flame, then breathe out slowly through pursed lips while counting to four.
- The client will inhale while counting to four, and then forcefully blow out on exhalation.
This answer is not correct because this is not the proper technique for pursed-lip breathing. The client will not forcefully blow out but rather exhale for a count of 4 through pursed lips.
The focus of this question is determining which description best illustrates the proper technique for pursed-lip breathing. Pursed-lip breathing is used by COPD clients to open the airways during exhalation to improve ventilation.
Pursed-lip breathing is a technique taught to emphysema clients to help with CO2 removal during exhalation. The goal of pursed-lip breathing is to increase pressure within the alveoli during exhalation and also to increase the length of time during exhalation to breathe out as much CO2 as possible. The proper way to perform pursed-lip breathing is to close the mouth, inhale, purse the lips, and exhale through a count of four.
