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?
Facilitating gas exchange
Regulating blood pressure
Removing excess interstitial fluid
Producing surfactant
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) Incorrect. Atrial contraction contributes to ventricular filling but is not typically the primary site of impairment in heart failure leading to pulmonary edema.
B) Incorrect. Ventricular relaxation (diastole) is necessary for ventricular filling, but the impaired contraction during systole is a more common issue in heart failure.
C) Correct. Impaired ventricular contraction (systole) in heart failure results in reduced forward flow of blood and leads to fluid backup in the lungs, contributing to pulmonary edema.
D) Incorrect. Electrical conduction in the heart may affect heart rhythm but is not directly related to the development of pulmonary edema.
Correct Answer is A
Explanation
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.
