A nurse on a medical-surgical unit is performing an admission assessment of a client who has COPD with emphysema. The client reports that he has a frequent productive cough and is short of breath. The nurse should anticipate which assessment findings for this client.

A. Clients with COPD often have low oxygen saturation levels; an oxygen saturation of 96% is not typical. B. Respiratory acidosis, not alkalosis, is more common in clients with COPD due to the retention of carbon dioxide. C. Petechiae on the chest is not commonly associated with COPD or emphysema. D. An increased anteroposterior diameter of the chest, often referred to as a "barrel chest," is a common physical finding in clients with emphysema due to lung hyperinflation.
