A home health nurse is assessing a client who has COPD. Which of the following findings indicates the need for a referral for pulmonary rehabilitation?

Rationale: A. Dyspnea at rest: Dyspnea at rest is a sign of advanced COPD, indicating that the client is experiencing significant respiratory difficulty. Pulmonary rehabilitation can help improve exercise tolerance and breathing, making this an appropriate reason for referral. B. Pursed-lip breathing: Pursed-lip breathing is a technique often used by clients with COPD to help manage shortness of breath. It is not an indication for pulmonary rehabilitation, but rather a self-management strategy. C. Clubbing of the fingers: Clubbing of the fingers can be a sign of chronic hypoxia and is commonly seen in advanced COPD. However, it does not directly indicate the need for pulmonary rehabilitation, although the condition may benefit from comprehensive care. D. SPO2 90%: A SpO2 of 90% is low but not necessarily an indication for referral to pulmonary rehabilitation. It is important to monitor oxygen levels, but this alone does not trigger the need for rehabilitation.
