In the context of a thoracentesis procedure, the correct identification of potential complications focuses on pneumothorax and bleeding. During the procedure, a needle is inserted into the pleural space to remove excess fluid or air. One of the most significant risks associated with this intervention is pneumothorax, which occurs when the pleura is punctured, allowing air to enter the pleural space. This can lead to lung collapse, resulting in respiratory distress or chest pain.

Bleeding is another critical complication that can occur if blood vessels are inadvertently punctured during the procedure. This could lead to a hemothorax, where blood accumulates in the pleural space, further complicating the patient’s clinical status.

While other options mention complications that have validity in different contexts, pneumothorax and bleeding are specifically the most relevant and common complications directly associated with thoracentesis. Understanding these complications emphasizes the importance of careful technique and monitoring during and after the procedure to ensure patient safety.
