Your patient presents with jugular vein distention, absent breath sounds on the left side, diminished breath sounds on the right side, tachycardia, and profound hypotension. You should?

• A. Monitor and transport the patient to a trauma center
• B. Place your patient on his right side
• C. Perform pericardiocentesis
• D. Decompress the left chest immediately

Answer: (D)

Think of this as a life-threatening obstructive shock from a tension pneumothorax. The jugular venous distention shows venous return is being impeded by the rising intrathoracic pressure, while the trauma patient with unilateral absent breath sounds and hypotension points to air trapped in the chest collapsing the lung and shifting the mediastinum. That pressure compromises both ventilation and the heart’s preload, so the blood pressure drops and the heart pumps faster in an attempt to compensate.

Immediate chest decompression is the priority because it quickly relieves the trapped air, allows the lung to re-expand, and restores venous return to the heart. This is typically done with needle decompression or chest tube placement on the affected side—here, the left side—without waiting for imaging.

Monitoring the patient or transporting them does not address the underlying pressure problem and could be fatal if delay occurs. Placing the patient on his right side wouldn’t relieve the tension. Pericardiocentesis would target cardiac tamponade, not a pneumothorax. Decompressing the left chest immediately directly treats the dangerous mechanism at work and stabilizes the patient.
