A condition in which part or all of the lung collapses is called?

• A. Atelectasis
• B. Adenoids
• C. Bronchoscopy
• D. Pleuritis

Answer: (A)

Lung collapse occurs when part or all of the lung cannot stay inflated and deflates, a condition known as atelectasis. This happens when air within the alveoli is not maintained, either because the airways are blocked by mucus or a foreign object or because external pressure (such as fluid, air, or a mass) compresses the lung tissue. When alveoli collapse, gas exchange drops in the affected area, leading to faster breathing and possibly lower oxygen levels. Clinically, you may hear reduced breath sounds over the involved region and notice dullness to percussion; chest imaging often shows loss of volume in the affected part of the lung. Adenoids are enlarged lymphatic tissue in the nasal passages, not related to lung collapse. Bronchoscopy is a procedure to look inside the airways, not a condition. Pleuritis is inflammation of the pleura and chest wall pain, not the collapse of lung tissue.
