Which of the following shows a correct cause and effect sequence in the development of acute respiratory distress syndrome (ARDS)?
A) Impaired alveolar compliance causing decreased surfactant production
B) Alveolocapillary membrane injury causing a massive inflammatory response
C) Hyaline membrane formation and fibrosis causing pulmonary edema
D) Increased alveolocapillary membrane permeability causing metabolic alkalosis

Question

Quizplus · Accepted Answer

All disorders causing ARDS cause massive pulmonary inflammation that injures the alveolocapillary membrane and produces severe pulmonary edema and inflammation.
All disorders causing ARDS cause massive pulmonary inflammation that injures the alveolocapillary membrane and produces severe pulmonary edema and inflammation.It does not affect surfactant.
ARDS does not cause hyaline formation.
Metabolic alkalosis occurs late,but inflammation occurs first.
