Pulmonary Edema

Pulmonary Edema ( 33 Questions)

A nurse is explaining the pathophysiology of pulmonary edema to a group of nursing students. Which physiological mechanism underlies the development of pulmonary edema?


Correct Answer: B

A) Incorrect. Increased lung compliance would not contribute to pulmonary edema; in fact, it might reduce the risk of fluid accumulation in the lungs.

B) Correct. Impaired alveolar fluid clearance, often due to altered pulmonary capillary permeability, is a key factor in the pathophysiology of pulmonary edema.

C) Incorrect. Constricted pulmonary blood vessels (vasoconstriction) would reduce blood flow to the lungs and are not a primary factor in pulmonary edema.

D) Incorrect. Enhanced left ventricular contractility, while beneficial for cardiac function, is not directly related to the development of pulmonary edema.
