a. it is caused by injury to the bronchioles

b. it can cause severe pulmonary edema

c. it is most commonly caused by exposure to inhaled irritants

d. macrophages are not involved in response

b. it can cause severe pulmonary edema

Rationale: Acute respiratory distress syndrome (ARDS) is characterized by damage that is done to the alveolar capillary membrane and causes severe pulmonary edema.

Which of the following is TRUE regarding the pathophysiology of asthma?
a. IgA is the major factor.
b. There is decreased vascular permeability.
