Final answer:
The priority finding for the nurse to report to the provider when assessing a client with COPD is Oxygen saturation of 92% on room air. In COPD, a decrease in oxygen saturation can indicate worsening lung function.
Step-by-step explanation:
The priority finding for the nurse to report to the provider when assessing a client with COPD is Oxygen saturation of 92% on room air. In COPD, the ability to effectively exchange oxygen and carbon dioxide is compromised, and a decrease in oxygen saturation can indicate worsening lung function. A saturation level of 92% is below the normal range (95%-100%) and requires immediate attention to prevent further respiratory distress.
