After a thoracentesis, a healthcare provider assesses a client. Which assessment finding warrants immediate action?
Correct Answer: D
Rationale: The correct answer is D because tracheal deviation indicates a potential tension pneumothorax, a life-threatening emergency requiring immediate intervention. Tracheal deviation occurs when there is a significant shift in the mediastinum due to increased pressure in the pleural space. This can compromise respiratory function and lead to respiratory failure. Options A, B, and C are not as urgent as tracheal deviation. Pain at 5/10 is expected post-thoracentesis, a small amount of drainage is common, and a pulse oximetry reading of 93% on low oxygen is concerning but not immediately life-threatening.
