Where should the chest drain tip be located to effectively drain pleural contents?

• A. The chest drain tip should be in the mediastinum.
• B. The chest drain should cross to the contralateral chest.
• C. The chest drain tip should be within the pleural space, directed toward the lung base to facilitate drainage.
• D. The chest drain tip should terminate in the chest wall.

Answer: (C)

To drain pleural contents effectively, the chest drain tip must stay inside the pleural space and be directed toward the lung base. This positioning uses gravity to help fluids collect at the dependent base and ensures the tube can continuously remove air or fluid. Placing the tip in the mediastinum risks injury to the heart and great vessels and won’t provide proper pleural drainage. Crossing to the opposite chest would misplace the tube and could injure structures on the other side. Ending the tip in the chest wall means the drain is outside the pleural space, so nothing relevant is drained.
