Answer to Question 1

ANS: A
Increased resonance can be detected in patients with hyperinflated lungs. Hyperinflation can re-sult from acute or chronic bronchial obstruction, such as asthma or emphysema.

Answer to Question 2

ANS: C
Any abnormality that increases lung tissue density, such as pneumonia, tumor, or atelectasis, re-sults in a loss of resonance and decreased resonance to percussion over the affected area. Pleural spaces filled with fluid, such as blood or water, also produce decreased resonance to percussion.
