During a meeting to resolve staffing issues and tardiness on a unit, the nurse manager invites the staff to each take a turn speaking and asks that everyone listen respectfully and avoids making personal or professional remarks about one another. The nurse manager is utilizing which step in the negotiation process?

A. Increased arterial oxygen: Clients with COPD typically experience chronic hypoxemia due to alveolar destruction, airway inflammation, and mucus production, which impair gas exchange. Rather than increased oxygen levels, they often have a decreased PaO₂, requiring supplemental oxygen therapy. However, excessive oxygen administration can suppress their respiratory drive, worsening CO₂ retention.
B. Increased pH: COPD is associated with respiratory acidosis due to chronic CO₂ retention from inadequate alveolar ventilation. While the kidneys compensate by increasing bicarbonate retention, the pH usually remains low or near normal in chronic cases rather than becoming elevated. A higher pH would indicate alkalosis, which is not typical in COPD unless there is an additional metabolic disturbance.
C. Increased carbon dioxide: COPD causes airway obstruction and reduced alveolar ventilation, leading to CO₂ retention (hypercapnia). As CO₂ accumulates in the blood, it lowers the pH, resulting in respiratory acidosis. Chronic hypercapnia is a hallmark of advanced COPD, and in response, the kidneys retain bicarbonate to partially compensate, stabilizing the pH over time but leaving PaCO₂ elevated.
D. Decreased alveolar function: While COPD does lead to progressive alveolar damage and reduced gas exchange, this is a structural and functional change rather than a specific abnormality seen in arterial blood gases. The primary ABG finding in COPD is hypercapnia, which reflects inadequate ventilation and CO₂ retention rather than just decreased alveolar function alone.

A. An adverse event. An adverse event is an unintended injury or complication resulting from medical care rather than the patient’s underlying condition. In this case, the surgical site infection (SSI) developed as a complication of surgery, requiring additional treatment. While adverse events may prolong recovery, they do not always indicate negligence or preventability.
B. A never event. Never events are serious, preventable medical errors that should not occur under proper care, such as surgery on the wrong site, retained surgical instruments, or administering the wrong medication. While SSIs are concerning, they are not classified as never events because they can occur even when proper precautions are taken.
C. A near miss. A near miss refers to an event that could have caused harm but was prevented before reaching the patient. Since the infection did occur and required intervention, it does not qualify as a near miss. A near miss example would be identifying and correcting a medication error before administration.
D. A sentinel event. Sentinel events involve unexpected occurrences that result in serious injury, permanent harm, or death, such as patient suicide, wrong-site surgery, or a fatal medication error. Although the infection required prolonged treatment, it did not lead to severe harm or death, making it an adverse event rather than a sentinel event.
