A nurse is explaining the role of the lymphatic system in pulmonary edema to a client. What is the primary function of the lymphatic system in managing fluid balance in the lungs?

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.

A) Incorrect. The primary role of the lymphatic system in the lungs is not gas exchange but rather fluid removal.

B) Incorrect. While the lymphatic system plays a role in overall fluid balance, it is not primarily responsible for regulating blood pressure.

C) Correct. The lymphatic system helps remove excess interstitial fluid from the lungs, preventing fluid accumulation and contributing to fluid balance.

D) Incorrect. Surfactant production is primarily related to maintaining lung compliance and preventing alveolar collapse but is not a primary function of the lymphatic system.
