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

Choice A rationale Clubbing of the fingers is a clinical sign characterized by the thickening of the fingertips and a loss of the normal angle at the nail bed. It occurs in chronic respiratory conditions like emphysema due to prolonged hypoxemia and the release of growth factors that increase tissue vascularity and thickness. While not present in all cases, it is a recognized finding in clients with long-standing obstructive pulmonary disease and chronic low oxygen saturation levels. Choice B rationale Shallow respirations are not a typical finding for emphysema. Instead, clients usually exhibit increased respiratory effort and prolonged expiration. In emphysema, the destruction of the alveolar walls leads to air trapping and loss of elastic recoil, which requires the client to use accessory muscles and often results in deep, labored breathing rather than shallow breaths. Shallow breathing might indicate different pathologies like pleuritic pain or neuromuscular weakness rather than the hyperinflation of emphysema. Choice C rationale A barrel chest is a classic clinical manifestation of emphysema. It results from chronic air trapping in the alveoli, which leads to hyperinflation of the lungs. This hyperinflation causes the anteroposterior diameter of the chest to increase until it equals the lateral diameter, giving the chest a rounded, barrel-like appearance. This physical change reflects the underlying pathophysiology of permanent enlargement of the air spaces and the destruction of the alveolar septa. Choice D rationale Dyspnea, or shortness of breath, is the most common and distressing symptom of emphysema. Initially occurring with exertion, it eventually progresses to dyspnea at rest as the lung tissue destruction worsens. It is caused by the mismatch between ventilation and perfusion and the increased work of breathing required to move air through damaged, non-elastic airways. The client often uses pursed-lip breathing to help maintain airway pressure and ease the sensation of breathlessness. Choice E rationale Bradycardia is not associated with emphysema. In fact, clients with chronic obstructive pulmonary diseases like emphysema are more likely to experience tachycardia. This is a compensatory mechanism where the heart rate increases to improve oxygen delivery to tissues in the presence of chronic hypoxemia. Furthermore, many medications used to treat emphysema, such as beta-agonists, can increase the heart rate. A slow heart rate would be an unexpected and unrelated finding in this client.
