What finding should the LPN expect in a client with a pneumothorax?

In a client with a pneumothorax, the expected finding would be reduced breath sounds on the affected side. This occurs because air accumulates in the pleural space, which can prevent the lung from fully expanding and limit the movement of air during ventilation. As a result, auscultation over the affected area may reveal diminished or absent breath sounds, indicating that airflow is obstructed or significantly reduced.

While other findings can be associated with various respiratory conditions, they do not pertain specifically to pneumothorax as directly as reduced breath sounds do. Blood-tinged sputum, increased anterior-posterior diameter, and a loud, rough, grating sound are more indicative of other conditions, such as pneumonia or pleurisy, rather than the specific physiological changes caused by a pneumothorax. Recognizing the significance of these auscultation findings is crucial for practical nursing, as it aids in appropriate assessment and management of respiratory issues.
