Answer to Question 1

ANS: C
The vibration created by percussion penetrates the lung to a depth of 5 to 7 cm below the chest wall.

Answer to Question 2

ANS: A
When auscultating over the lung parenchyma of a healthy individual, soft, muffled sounds are heard. These normal breath sounds, referred to as vesicular breath sounds, are lower in pitch and intensity than bronchovesicular breath sounds. Vesicular sounds are heard primarily during inha-lation, with only a minimal exhalation component (Table 16-2).
