What is an expected finding in the drainage-collection chamber of a client who has just returned from a thoracotomy?

1. 500 mL of drainage

2. 25 mL of drainage

3. 50 mL of drainage

4. No drainage present

The correct answer is: 50 mL of drainage

When a patient returns from a thoracotomy, it is common to see some drainage in the collection chamber due to the surgical procedure that involves opening the chest cavity. The expected amount of drainage can vary based on the individual patient and specifics of the surgery, but a range of 50 mL is often considered normal during the immediate post-operative period. Having 50 mL of drainage indicates that the body is likely processing normal fluid that can accumulate after surgery, such as blood or serous fluid. This amount is not alarming and generally suggests that there is no significant complication, such as excessive bleeding or blockage. In contrast, a significantly larger volume like 500 mL could suggest active bleeding or other complications that would require immediate medical attention. No drainage present can also raise concerns, as it might indicate issues with the thoracostomy tube, leading to complications such as a collapsed lung. Meanwhile, 25 mL of drainage can be on the low side for immediate post-operative expectations. Therefore, seeing around 50 mL helps assure that the postoperative status is within the expected recovery trajectory.
