To administer medications

To perform routine blood tests

To remove excess fluids and prevent fluid accumulation

The primary function of drainage tubes postoperatively is to remove excess fluids and prevent fluid accumulation. After surgery, the body may produce fluids due to inflammatory responses, surgical trauma, or other factors. These fluids, if not drained, can lead to complications such as seromas, hematomas, and infection. By using drainage tubes, healthcare providers can effectively manage these fluids, ensuring proper healing and minimizing the risk of complications.

Using drainage tubes allows the surgical site to remain clean and reduces pressure buildup that could interfere with recovery. This proactive measure can lead to better outcomes, as effective fluid management is crucial for post-surgical care and helps the patient heal appropriately. The other options, while important aspects of patient care, do not align with the specific and primary role of drainage tubes in the context of postoperative management.
