A nurse is caring for a client immediately following endotracheal intubation. The nurse should assess the client for complications by performing which of the following priority action?

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. Conduct a study about the time and money costs of implementing the change. While analyzing costs and time efficiency is important for evaluating resource utilization, it does not directly measure the effectiveness of the changes in reducing medication errors. The primary goal of quality improvement is to assess patient safety outcomes rather than financial impact alone.
B. Establish a benchmark to identify a standard of performance. Setting benchmarks is a useful strategy for quality control, but it is a preliminary step in the evaluation process. Benchmarks provide a target for improvement, but they do not measure whether the specific changes implemented have led to a reduction in medication errors.
C. Compare the number of medication errors before and after the action was implemented. The most effective way to evaluate the success of the changes is to analyze pre- and post-intervention data. Comparing the frequency of medication errors before and after the quality improvement measures allows for an objective assessment of whether the interventions have led to a meaningful reduction in errors.
D. Provide the staff with a questionnaire to quantify staff satisfaction with the changes. Staff feedback is valuable for assessing workflow and morale, but it does not directly measure the effectiveness of the intervention in reducing medication errors. A reduction in actual error rates provides a more concrete evaluation of the intervention’s success.
