What is the priority action a nurse should take when transporting a client with a chest tube to another department?

The priority action when transporting a client with a chest tube is to keep the drainage system below the level of the client's chest at all times. This is critical to ensure that gravity assists in the proper functioning of the chest tube system, allowing for effective drainage of air or fluid from the pleural space. If the system is not kept below the chest level, there is a risk of fluid backflow into the pleural cavity, which could lead to complications such as a compromised lung re-expansion, risk of infection, or increased respiratory distress.

Maintaining this position enhances the efficacy of the tube and minimizes potential complications during transport. It's crucial to recognize that ensuring the drainage system is properly positioned is more important than other actions that could disrupt the function of the chest tube or the drainage system.
