In tension pneumothorax, which statement is true regarding diagnosis and management?

Explanation:
Tension pneumothorax is a life-threatening emergency where the diagnosis is made clinically and treatment must not be delayed for imaging. The danger comes from air entering the pleural space and acting like a one-way valve, so intrapleural pressure rises rapidly, the lung on the affected side collapses, and the mediastinum shifts, impairing venous return to the heart and precipitating shock. In a patient who is acutely short of breath, with signs such as severe distress, hypotension, tachycardia, absent or diminished breath sounds on the involved side, hyperresonance to percussion, and often distended neck veins, you should act immediately. Definitive management is rapid decompression followed by definitive drainage. The common immediate step is needle thoracostomy to relieve the pressure, followed as soon as possible by chest tube placement to re-expand the lung and prevent recurrence. Do not wait for imaging to confirm the diagnosis before decompressing. Imaging such as chest X-ray, CT, or ultrasound can help in stable patients or after initial management to confirm findings, but they should not delay emergent treatment in a suspected tension physiology.
