What information should a nurse provide to a coworker who is caring for a client scheduled to have a thoracentesis for a pleural effusion?

The correct answer emphasizes an important consideration when performing a thoracentesis: rapid removal of large amounts of fluid can lead to cardiovascular collapse. This is crucial knowledge for anyone involved in the patient’s care because the thoracic cavity can respond negatively to sudden shifts in pressure and volume. If too much fluid is withdrawn too quickly, it can result in significant changes in hemodynamics, potentially leading to complications such as hypovolemic shock or cardiovascular instability. Therefore, understanding the risks associated with the procedure helps ensure patient safety and informs the pre-procedure planning and execution.

The knowledge provided in this choice highlights the need for careful monitoring and adherence to procedural guidelines to mitigate risks. It reinforces the importance of a thorough assessment of the patient's fluid status and ensuring that the procedure is conducted in a controlled and safe manner, maintaining awareness of how changes in intrathoracic pressure may affect the patient.
