What nursing action is essential when caring for a patient with a chest tube?

Ensuring the collection chamber is below the level of the chest is a crucial nursing action when caring for a patient with a chest tube because it promotes effective drainage of fluid or air from the pleural cavity. Gravity plays an essential role in the drainage process; having the collection chamber positioned below the chest ensures that any accumulated fluid or air can flow freely into the chamber rather than re-entering the thoracic cavity. This positioning helps to prevent complications such as tension pneumothorax and allows for proper monitoring of the output.

In addition to supporting drainage, maintaining the appropriate height of the collection chamber can also aid in achieving the desired pressure within the pleural space. If the collection chamber is too high, it may lead to a situation where the tube can become obstructed, reducing the efficacy of the chest tube.

The other choices involve practices that may either be inappropriate or could pose risks. For instance, positioning a patient in a prone position is generally not recommended because it can impede the drainage of air or fluid and may increase the risk of complications. Clamping the tube intermittently can be risky unless specifically ordered by a healthcare provider, as it can result in a build-up of air or fluid in the pleural space.
