Where should the nurse perform the insertion for a chest tube in a client with a left-sided pneumothorax?

• A. Right midaxillary line at the 4th-5th intercostal
• B. Left midaxillary line at the 4th-5th intercostal
• C. Left anterior axillary line at the 2nd-3rd intercostal
• D. Midsternal line at the 6th intercostal

Answer: (B)

The appropriate location for chest tube insertion in a patient with a left-sided pneumothorax is indeed the left midaxillary line at the 4th-5th intercostal space. This region is optimal because it allows access to the pleural space while minimizing risk to nearby structures such as the lung and major blood vessels. When a pneumothorax occurs, particularly if it's a tension pneumothorax, prompt decompression of the pleural space is critical. The midaxillary line location at the 4th-5th intercostal space is a commonly accepted standard for chest tube placement to effectively drain air or fluid from the pleural cavity on the affected side, which in this case is the left. This location is chosen to ensure that the tube is inserted into the correct anatomical space while also being mindful of the underlying structures (like the lungs and heart) that could be injured at higher levels, such as in the anterior axillary or midsternal areas. Therefore, the left midaxillary line provides a safe and effective approach for addressing a left-sided pneumothorax.
