A nurse is caring for an adult client.

The nurse should determine the assessment findings are consistent with which of the following disease processes?

For each assessment finding, click to specify if the assessment finding is consistent with laryngotracheobronchitis (LTB), epiglottitis, or foreign body aspiration. Each finding may support more than 1 disease process.

A. To facilitate weaning off the mechanical ventilator. While PEEP is an important component of mechanical ventilation, its primary function is not to facilitate weaning. Instead, it improves oxygenation by preventing alveolar collapse. Weaning involves gradually reducing ventilatory support, but PEEP is typically adjusted based on oxygenation needs rather than as a direct step in weaning.
B. To decrease trapped oxygen in the alveoli. PEEP does not decrease trapped oxygen; instead, it maintains alveolar patency and prevents atelectasis. In conditions like ARDS, alveoli tend to collapse due to fluid accumulation and inflammation, and PEEP helps counteract this collapse to improve gas exchange. Reducing "trapped" oxygen is not a function of PEEP.
C. To promote independent breathing efforts. PEEP itself does not promote spontaneous breathing; instead, it provides positive pressure at the end of exhalation to improve oxygenation. In fact, high levels of PEEP can suppress spontaneous breathing by increasing intrathoracic pressure, requiring careful adjustment to balance oxygenation and ventilatory effort.
D. To keep the airways and small lung spaces open. PEEP prevents alveolar collapse by maintaining positive pressure in the lungs at the end of expiration. This improves oxygenation and gas exchange, which is critical in ARDS, where alveoli are prone to collapse due to inflammation and fluid accumulation. Keeping alveoli open reduces shunting and improves oxygen delivery to tissues.

A. Clubbing of the fingers: This finding is often associated with chronic respiratory conditions, including emphysema, due to prolonged hypoxia. The chronic low oxygen levels can lead to changes in the nail beds, resulting in clubbing as the body attempts to compensate for the decreased oxygenation. Therefore, clubbing is a common assessment finding in clients with emphysema.
B. Bradycardia: Emphysema typically does not cause bradycardia; instead, clients may experience tachycardia due to increased respiratory effort and oxygen demand. While individual variations can occur, bradycardia is not a standard finding in clients with emphysema, making this option less likely to be present.
C. Barrel chest: This is a common physical assessment finding in clients with emphysema. The chronic overinflation of the lungs leads to a characteristic increase in the anteroposterior diameter of the chest, resulting in a barrel-shaped appearance. This occurs as the diaphragm becomes flattened and the rib cage is expanded from prolonged air trapping.
D. Dyspnea: Shortness of breath, or dyspnea, is a hallmark symptom of emphysema. As the disease progresses, clients may experience increased difficulty in breathing, especially during exertion, due to the destruction of alveoli and reduced lung elasticity. This finding is expected and significant in the assessment of a client with emphysema.
E. Deep respirations: In emphysema, clients often exhibit shallow, rapid breathing patterns rather than deep respirations. The loss of elasticity in the lungs leads to difficulty in full lung expansion, which can result in a more shallow and increased respiratory rate. Therefore, deep respirations are not a typical finding in clients with emphysema.
