A nurse is caring for a client who reports experiencing alteration in sense of smell following surgery for a total laryngectomy. The nurse should address the client's concern through which of the following response?

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. Advocacy: Advocacy involves representing the interests and needs of individual patients or groups within the healthcare system. While the nurse's actions may indirectly benefit patients by improving care standards, the focus here is on systemic changes rather than individual patient representation. Advocacy often involves lobbying for resources, policy changes, or addressing ethical concerns on behalf of patients, which is not the primary goal of the actions taken in this scenario.
B. Quality improvement: This term best describes the nurse's actions as it focuses on enhancing healthcare practices and patient outcomes through systematic efforts. By identifying the increase in pressure injuries and collaborating with management to implement a new policy, the nurse is actively participating in a quality improvement initiative aimed at reducing risks and improving care protocols in the ICU. This approach reflects a commitment to continuous improvement in patient safety and care standards, aligning with best practices in healthcare.
C. Case Management: Case management primarily involves coordinating care for individual patients, ensuring they receive appropriate services, and managing their healthcare journey. While the nurse may address pressure injuries at the unit level, the actions taken are broader and not confined to individual patient care. Case management emphasizes individualized care plans and resource allocation rather than addressing systemic issues affecting a group of patients in the ICU.
D. Collaboration: Collaboration refers to working together with others, such as colleagues and management, to achieve common goals in patient care. While the nurse did collaborate with the manager to develop and implement the new policy, collaboration alone does not capture the proactive approach taken to address the increase in pressure injuries. It emphasizes teamwork but lacks the focus on systematic quality enhancement that characterizes quality improvement efforts, which aim to implement lasting changes in practices and outcomes.
