A client with chronic obstructive pulmonary disease (COPD) receives oxygen therapy. Which finding requires immediate intervention by the nurse?
Correct Answer: B
Rationale: The correct answer is B: Respiratory rate of 10 breaths per minute. In a client with COPD, a respiratory rate of 10 breaths per minute indicates severe respiratory depression and impending respiratory failure. Immediate intervention is necessary to prevent hypoxia and respiratory arrest. Oxygen saturation of 91% (choice A) is low but not as critical as a low respiratory rate. Shortness of breath (choice C) is expected in COPD but does not indicate immediate danger. Use of accessory muscles (choice D) is a sign of respiratory distress, but a low respiratory rate is more concerning for imminent respiratory failure.
