Question

Quizplus · Accepted Answer

A "check-valve" bronchial obstruction is a type of airway obstruction where air can enter during inspiration but become trapped during expiration. This can lead to hyperinflation of the affected lung segment or lobe, which can be better visualized on an expiratory chest radiograph.

Answer: C, D
 A pleural effusion is an accumulation of fluid in the pleural space, which can be better visualized on both inspiratory and expiratory chest radiographs. Air-space consolidation refers to an area of the lung where the alveoli are filled with fluid or debris, and an expiratory chest radiograph can help differentiate between true consolidation and the artifact of overlying soft tissue. Hilar lymphadenopathy refers to enlarged lymph nodes in the hilar region of the lungs, which may not be affected by changes in lung volume and would not be significantly impacted by the use of expiratory chest radiography.
