➡️ A 55-year-old male patient with a pneumothorax has a pleural drainage system in place. Upon assessment, you note that there is no bubbling in the suction control chamber. After confirming that suctioning is turned on, which of the following would you recommend?
A. Increase the power of the suction control
B. Withdraw the chest tube about 3-4 cm
C. Check the connecting tubing for leaks
D. Add more water to the suction control chamber

For the TMC Exam, you definitely need to be familiar with chest tubes and pleural drainage systems. Here are a few tidbits that you should remember:
 
➡️ If there is no bubbling in the suction chamber, this means that there could be a leak in the system, or you may just need to increase the vacuum suction pressure. On the other hand, if there is bubbling in the water seal chamber, this is normal when a pneumothorax is present. This lets you know that the air is being drained properly.

➡️ However, the bubbling in the water seal chamber should not be continuous. It should be sporadic. If there is continuous bubbling, it means that a new leak has developed. You should check for a loose connection. If the collection chamber becomes full, you should clamp the chest tube and exchange the system with an empty chamber. If there has been no change in drainage, there may be a kink in the tubing.

So taking this into consideration, since there is no bubbling in the suction chamber, we know that the correct answer has to be either A or C. But the question states that suctioning is turned on, so the best thing to do in this case is to check the tubing to see if it has any leaks.
