What is the most likely reason for placing a chest tube?

Placing a chest tube is primarily indicated for managing pleural effusion or pneumothorax. A pleural effusion occurs when excess fluid accumulates in the pleural space, leading to difficulty breathing and potential lung collapse. A chest tube allows for the drainage of this fluid, helping to restore normal lung function and alleviate symptoms.

In the case of a pneumothorax, where air enters the pleural space and can cause the lung to collapse, a chest tube is inserted to remove the air, allowing the lung to re-inflate and function properly. The chest tube creates a pathway for drainage to occur, either through suction or gravity, ensuring that air or fluid can be continuously evacuated from the pleura.

Other options do not align with the primary function of a chest tube. Monitoring heart rhythm involves the use of an electrocardiogram (ECG) or telemetry systems, not a chest tube. Administering medications typically occurs through different routes such as intravenous (IV) or intramuscular (IM) injections, while supplemental oxygen is delivered through devices like nasal cannulas or masks, and does not require a chest tube. The specific purpose of chest tube placement is centered around addressing the complications involving the pleural space, which subst
