Nurse Jordan, a seasoned member of the team, has been openly belittled by Nurse Taylor, a newer nurse. During handoffs, Nurse Taylor makes sarcastic remarks about Nurse Jordan's decisions, saying, "I can't believe you thought that was the right approach." This behavior creates a tense atmosphere and affects team dynamics. What type of behavior is Nurse Taylor exhibiting in this scenario?

A. Poorly coordinated care and nosocomial infections are examples of errors: While poorly coordinated care can lead to adverse events, nosocomial infections are typically classified as healthcare-associated infections rather than errors. Errors generally refer to mistakes made in clinical practice that can lead to harm, whereas nosocomial infections are outcomes that arise from the healthcare environment.
B. As many as 90% of medication errors are preventable: This statement is true and highlights the significant opportunity for improvement in patient safety. Recognizing that a large percentage of medication errors can be prevented underscores the importance of implementing safety protocols, effective communication, and education to reduce the likelihood of errors occurring in clinical practice.
C. Errors of execution are usually intentional and occur because of time or resource constraints: This statement is misleading, as errors of execution typically refer to mistakes made during the performance of a task rather than intentional actions. These errors often occur due to lack of knowledge, skill, or attention rather than being intentional, and they are not solely attributed to time or resource constraints.
D. Medication errors are adverse events: While medication errors can lead to adverse events, not all medication errors result in harm. An adverse event is defined as an injury caused by medical management rather than the underlying condition of the patient, so this statement is not entirely accurate. Medication errors can be classified as near misses or adverse events, depending on whether they resulted in harm to the patient.

A. Encourage the client to take breaks from oxygen use to prevent tolerance. Oxygen therapy does not cause "tolerance," and taking breaks can lead to hypoxemia in COPD clients. Continuous low-flow oxygen is essential to maintaining adequate oxygenation while avoiding hypercapnia. Stopping oxygen therapy intermittently can increase the risk of respiratory distress.
B. Assess cheeks and posterior ears for signs of skin breakdown. While it is important to monitor for pressure injuries from nasal cannula tubing, this is a general nursing consideration for all patients receiving oxygen therapy. It is not the highest priority when managing oxygen therapy in clients with COPD, where maintaining appropriate oxygen levels is critical.
C. Maintain nasal oxygen at a 1 to 2 liter/minute flow rate. Clients with COPD often have chronic CO₂ retention and rely on hypoxic drive for ventilation. Administering high-flow oxygen can suppress their respiratory drive, leading to CO₂ narcosis and respiratory failure. To prevent this, oxygen should be administered at the lowest effective flow rate, typically 1 to 2 L/min via nasal cannula, while closely monitoring oxygen saturation and blood gases.
D. Teach the client how to safely increase oxygen flow when they deem necessary. Allowing a client with COPD to adjust their oxygen flow independently can be dangerous, as excessive oxygen can lead to hypercapnia and respiratory depression. Oxygen adjustments should be made based on clinical assessments and healthcare provider orders.
