Advanced Patient Assessment Practice Exam

Which radiologic term confirms the presence of intrapulmonary disease?

1. Compression atelectasis

2. Platelike atelectasis

3. Air bronchogram

4. Sulcus sign

The correct answer is: Air bronchogram

The identification of an air bronchogram is pivotal in confirming intrapulmonary disease, particularly conditions such as pneumonia, pulmonary edema, or lung tumors. An air bronchogram occurs when air-filled bronchi are made visible against an opacified alveolar pattern, which typically denotes that the alveoli are filled with fluid, pus, or other materials, thereby indicating pathology within the lung parenchyma. The presence of air bronchograms signifies that while the bronchi themselves are air-filled, the surrounding lung tissue has undergone alteration due to disease, demonstrating the contrast needed to confirm intrapulmonary involvement. This radiologic feature provides insight into the underlying processes affecting lung function, assisting healthcare professionals in diagnosing and determining the severity of various pulmonary conditions.
