The nurse clarifies that when interstitial edema occurs in the lung tissue, ventilation is inhibited by: (Select all that apply.)
a. thickened alveolar membranes.
b. pus formation.
c. alveoli filling with fluid.
d. surfactant evaporation.
e. failure of gas to diffuse across membrane.
A, C, E
Interstitial edema will cause problems that affect the alveoli: thickened walls and filling with fluid that obstructs gas exchange across the thickened walls. Pus formation is associated with infection. Surfactant decreases surface tension on the alveolar wall, allowing it to expand more easily with inspiration and preventing alveolar collapse on expiration.
