Mycobacterium tuberculosis is particularly damaging to the lungs because of the:
 
  a. healing of a tubercle.
  b. formation of micropulmonary emboli.
  c. increased mucus production.
  d. irreversible bronchospasm that it causes.

Question 2

The respiratory therapist is performing palpation on a patient recently admitted to the medical ward. The therapist notes decreased tactile fremitus over the right lung.
 
  Which of the following could MOST likely be the cause for this physical exam finding?
  a. Right-sided atelectasis
  b. Right-sided pneumothorax
  c. Right-sided pleural effusion
  d. Right-sided pleural tumor

Answer to Question 1

A
As the lung undergoes the healing process, tissue fibrosis and calcification occur in each of the tubercle sites. This results in lung retraction and scarring and the distortion of bronchi.

Answer to Question 2

A
Tactile fremitus decreases when anything obstructs the transmission of vibration. Such conditions include tumors or thickening of the pleural cavity, pleural effusion, and pneumothorax. Tactile fremitus increases in patients with atelectasis.
