The nurse is caring for the client following a thoracentesis. (Select the 3 findings that require immediate follow-up.)

A. Decreased lung sounds may indicate pneumothorax or reaccumulation of fluid, requiring immediate follow-up. B. Tachycardia after thoracentesis can signal hypoxemia or developing complications such as pneumothorax or bleeding. C. Oxygen saturation of 95% is within normal limits and does not require immediate follow-up. D. Air leakage into the tissues following thoracentesis can signal a pneumothorax, which requires prompt intervention. E. A midline trachea is expected and reassuring; tracheal deviation would be the urgent finding. F. This is expected and indicates there is no active bleeding or drainage.
