Correct Answer is A
Explanation
A) Correct. Increased hydrostatic pressure in pulmonary capillaries, often due to left ventricular failure, leads to the filtration of fluid from the capillaries into the alveoli and interstitial spaces, causing pulmonary edema.
B) Incorrect. Decreased capillary permeability is not typically a primary factor in the development of pulmonary edema.
C) Incorrect. Enhanced lymphatic drainage from the lungs is not a primary mechanism responsible for the accumulation of fluid in pulmonary edema.
D) Incorrect. Elevated colloid osmotic pressure in pulmonary vessels would oppose fluid accumulation in the alveoli and is not a primary cause of pulmonary edema.
