A nurse is caring for a client suspected of having pulmonary edema. Which diagnostic test is commonly used to assess the severity and underlying 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.

A) Correct. Diuretics are commonly used in the management of pulmonary edema to reduce fluid volume, preload, and afterload on the heart.

B) Incorrect. Antibiotics are used to treat bacterial infections and are not typically used as a primary treatment for pulmonary edema.

C) Incorrect. Bronchodilators are used to relieve airway constriction and are not the primary treatment for pulmonary edema.

D) Incorrect. Anticoagulants are used to prevent blood clot formation and are not the primary treatment for pulmonary edema.
