  c. 1, 3, and 4 only
  d. 1, 2, 3, and 4

Question 2

While percussing a patient's chest wall, you encounter an area that produces a decreased reso-nance to percussion. Which of the following are potential causes of this finding?
 
  1. Pneumothorax
  2. Pleural effusion
  3. Pneumonia
  4. Atelectasis
  a. 2 and 3 only
  b. 2 and 4 only

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.
