A nurse is collecting data from a client who has emphysema. Which of the following findings should the nurse expect? (Select all that apply.)

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.

A. The patient's Spo2 is 97% on 2L NC:

This assessment finding indicates that the patient's oxygen saturation level (SpO2) is 97% while receiving 2 liters per minute of oxygen via nasal cannula. Oxygen saturation is a measure of the percentage of hemoglobin saturated with oxygen in the blood. A SpO2 level of 97% suggests adequate oxygenation, which is essential for effective gas exchange. Therefore, if the patient's SpO2 is within the target range on the prescribed oxygen therapy, it indicates that the interventions aimed at improving gas exchange have been effective.

B. The patient appears comfortable:

While patient comfort is important, it is not a direct indicator of effective gas exchange. A patient may appear comfortable for various reasons, such as pain relief, proper positioning, or emotional support, but this does not necessarily reflect improved gas exchange. Therefore, while comfort is an important aspect of nursing care, it is not specifically indicative of the effectiveness of interventions for impaired gas exchange.

C. The patient is coughing up copious white sputum:

The presence of copious white sputum does not directly indicate improved gas exchange. White sputum may suggest various conditions, such as respiratory tract infections or inflammation, but it does not provide direct information about gas exchange efficiency. Effective gas exchange involves the exchange of oxygen and carbon dioxide at the alveolar-capillary membrane, which cannot be assessed solely based on sputum production.

D. The patient is able to move out of bed without difficulty:

The ability to move out of bed without difficulty may indicate improved overall physical function or mobility, but it does not specifically reflect improved gas exchange. Gas exchange primarily involves the transfer of oxygen from the alveoli into the bloodstream and the removal of carbon dioxide from the bloodstream into the alveoli for exhalation. While improved gas exchange may lead to enhanced physical endurance and reduced dyspnea, the ability to move out of bed without difficulty is not a direct measure of gas exchange efficiency.
