ARRT Patient Care Practice Exam

Chest drainage systems should always be kept:

1. Below the level of the patient's chest

2. Above the patient's chest

3. At the level of the patient's diaphragm

4. None of the above

The correct answer is: Below the level of the patient's chest

Keeping chest drainage systems below the level of the patient's chest is crucial for the proper functioning of the system. This positioning utilizes gravity to facilitate the drainage of fluid or air from the pleural space into the collection chamber, which helps prevent backflow into the chest cavity. If the drainage system is positioned above the chest, it can create a situation where fluid or air may not drain effectively, potentially leading to complications such as re-accumulation of fluid or air in the pleural space. Additionally, ensuring the drainage system is below the level of the chest helps maintain negative pressure within the pleural cavity, which is essential for normal lung expansion and function. This principle is vital in clinical settings to promote patient safety and recovery. The other options do not adhere to best practices in managing chest drainage and could compromise the effectiveness of the treatment.
