A client with COPD who smokes 1 PPD presents for a routine appointment. Which client statement causes the nurse to suspect an increase in dyspnea?

A. The statement "I prop myself up at night to sleep" indicates orthopnea, which is difficulty breathing when lying flat. Orthopnea occurs because in clients with COPD, the lungs have reduced elastic recoil and airflow obstruction, leading to air trapping and hyperinflation. When lying flat, the diaphragm is compressed, and the lungs cannot fully expand, worsening shortness of breath. Needing to use pillows or sit upright to sleep is a key sign of worsening respiratory function or increased dyspnea. This symptom signals that the client’s COPD may be progressing or that there is an acute exacerbation, requiring prompt assessment of oxygenation, lung sounds, and respiratory effort. B. Saying "I decided to put on some makeup today" reflects engagement in activities of daily living and suggests that the client has functional capacity and energy. This statement does not indicate increased shortness of breath. C. A productive morning cough is a chronic symptom of COPD caused by excess mucus production and impaired mucociliary clearance. While it is part of the disease process, it does not necessarily indicate an acute increase in dyspnea unless it is accompanied by other symptoms such as increased sputum, wheezing, or shortness of breath. D. Weight gain could be related to fluid retention, dietary changes, or other factors, but on its own it does not directly indicate worsening dyspnea. If associated with edema or orthopnea, it may suggest heart failure, but without these signs, it is not the primary indicator of increased respiratory distress.
