Answer to Question 1

ANS: A
Subcutaneous emphysema is caused by air trapped in the subcutaneous tissues and is usually due to an air leak from the lung.

Answer to Question 2

ANS: B
When possible, the patient should be sitting upright in a relaxed position. Instruct the patient to breathe a little more deeply than normal through an open mouth. Inhalation should be active, with exhalation passive. Place the bell or diaphragm directly against the chest wall when possible, because clothing may produce distortion. The tubing must not be allowed to rub against any ob-jects, because this may produce extraneous sounds, which could be mistaken for adventitious lung sounds.
