Answer to Question 1

ANS: C
The presence of gas bubbles within the fluid without prior surgery or needle insertion (which can introduce air) establishes the diagnosis of empyema.

Answer to Question 2

ANS: B
The clinician can easily detect a pneumothorax on the standard chest film in most cases by seeing the lung margin and noting absence of bronchovascular markings between the lung margin and the inner aspect of the chest wall. Visualizing a small pneumothorax may be assisted by taking the chest radiograph when the patient exhales.
