If the collection chamber becomes full, what should the nurse do before transport?

When the collection chamber of a chest tube drainage system becomes full, the appropriate action for the nurse is to empty the collection chamber. This is crucial because a full chamber can prevent proper drainage of pleural fluid or air, which can lead to complications such as re-accumulation of fluid or air in the pleural space and diminished respiratory function.

By emptying the collection chamber, the nurse ensures that the drainage system continues to function effectively, allowing for optimal monitoring and facilitating the patient's recovery. It also makes it easier to transport the patient, as a full chamber may lead to spills or further complications during movement.

The other options may not adequately address the situation. Clamping the chest tube could cause a build-up of pressure in the pleural space, potentially leading to lung collapse. Disconnecting from the suction or maintaining fluid levels does not resolve the immediate issue of the full collection chamber and could hinder ongoing drainage. Therefore, emptying the collection chamber is the correct course of action to ensure safe transport and effective management of the patient’s condition.
