A nurse is collecting data on a client who has COPD. Which of the following findings should the nurse expect?

A. Instruct the client to use a pursed-lip breathing technique.

Pursed-lip breathing is a technique commonly used to help relieve dyspnea, particularly in individuals with COPD. This technique involves breathing in through the nose and exhaling slowly through pursed lips, which helps to prolong exhalation, reduce airway collapse, and improve oxygen exchange. While pursed-lip breathing can be beneficial, it should not be the priority action when the client reports difficulty breathing. Before initiating any breathing techniques, the nurse should first assess the client's respiratory status to determine the severity of the breathing difficulty and whether additional interventions are necessary.

B. Evaluate the client's respiratory status.

This is the correct priority action in this scenario. When a client with COPD reports difficulty breathing, the nurse's first step should be to thoroughly assess the client's respiratory status. This assessment involves evaluating respiratory rate, depth, effort, oxygen saturation levels, auscultating lung sounds, and assessing for signs of respiratory distress. By conducting a comprehensive assessment, the nurse can determine the severity of the client's symptoms, identify any potential exacerbating factors or complications, and make informed decisions regarding appropriate interventions.

C. Increase the oxygen flow to 3 L/min.

While increasing the oxygen flow may be a consideration if the client's oxygen saturation is low, it should not be the immediate priority without first assessing the client's respiratory status. Increasing oxygen flow without proper assessment could potentially worsen hypercapnia in some COPD patients and may not address the underlying cause of the client's difficulty breathing. Therefore, this action should be based on assessment findings rather than being the initial response.

D. Have the client cough and expectorate secretions.

Coughing and expectorating secretions can be helpful in clearing the airways and improving breathing in individuals with COPD, especially if secretions are contributing to the difficulty breathing. However, similar to the pursed-lip breathing technique, this action should not be the priority without first assessing the client's respiratory status. The nurse should determine whether secretions are indeed present and causing the difficulty breathing before instructing the client to cough and expectorate. Therefore, this option should follow a thorough respiratory assessment.

A. Expiratory wheeze

Expiratory wheeze is a high-pitched, musical sound heard primarily during expiration. It occurs when air passes through narrowed airways due to bronchoconstriction, inflammation, and increased mucus production, which are characteristic features of an acute asthma exacerbation. Expiratory wheezes are commonly heard upon auscultation of the chest in individuals experiencing asthma exacerbations.

B. Pleural friction rub

Pleural friction rub is a dry, crackling or grating sound heard during both inspiration and expiration. It typically occurs when the inflamed pleural surfaces rub against each other during breathing. Pleural friction rub is associated with conditions such as pleurisy (inflammation of the pleura) or pleural effusion (accumulation of fluid in the pleural space), rather than asthma exacerbations.

C. Fine rales

Fine rales, also known as fine crackles, are brief, high-pitched, discontinuous sounds heard primarily during inspiration. They are typically associated with conditions involving the small airways and alveoli, such as pulmonary fibrosis or congestive heart failure. Fine rales are not commonly heard in asthma exacerbations.

D. Rhonchi

Rhonchi are low-pitched, snoring or rattling sounds heard primarily during expiration. They result from the passage of air through airways obstructed by thick mucus or secretions. While rhonchi may be heard in individuals experiencing asthma exacerbations, they are less characteristic than expiratory wheezes, which are more commonly associated with asthma exacerbations. Rhonchi are often associated with conditions such as chronic bronchitis or pneumonia.
