A nurse is caring for a client who had a thoracentesis 2 hr ago. Which of the following findings should the nurse expect?

Rationale: A. Increased lung expansion: Thoracentesis removes excess pleural fluid or air from the pleural space, allowing the affected lung to re-expand. As a result, the client typically experiences improved lung expansion and enhanced ventilation, which can be assessed by symmetric chest movement, improved breath sounds, and increased oxygenation. B. Dry, nonproductive cough: A mild cough may occur during or immediately after the procedure due to irritation of the pleura, but a persistent dry, nonproductive cough is not an expected finding. It could indicate irritation, infection, or a developing complication if it is severe or prolonged. C. Crepitus at the puncture site: Crepitus, or subcutaneous air under the skin, suggests a pneumothorax or air leak and is considered an abnormal finding following thoracentesis. While small amounts of air can occasionally enter the subcutaneous tissue, noticeable crepitus requires immediate assessment and monitoring. D. Rapid, shallow respirations: Tachypnea and shallow breathing are potential signs of respiratory distress, pneumothorax, or pain following thoracentesis. These findings are not expected in a routine, uncomplicated recovery and should prompt urgent evaluation for post-procedure complications.
