What should be readily available at the bedside of a client with a chest tube in place to ensure safety?

Having a bottle of sterile water readily available at the bedside of a client with a chest tube is essential for safety because it serves a critical function in maintaining the patency and proper functioning of the chest tube drainage system. In the case of a disconnection between the chest tube and the drainage system, the sterile water can be used to submerge the end of the chest tube. This creates a water seal, preventing air from entering the pleural space, which could lead to tension pneumothorax or other complications.

The sterile water also can be utilized to make adjustments to the drainage system, such as ensuring that the water seal chamber has the appropriate level to facilitate effective drainage and prevent backflow or air leaks. It is a simple yet vital measure that enhances patient safety in case of emergencies related to the chest tube.

In contrast, the other items listed are not designed for the immediate needs associated with a chest tube's functionality. A tracheostomy tray is used for airway emergencies unrelated to chest tube placement. Having another sterile chest tube at the bedside may not be practical or necessary, as this scenario would typically require clinical intervention beyond simply having a replacement. A spirometer, while beneficial for promoting lung expansion and preventing atelectasis, does not directly
