A client is being evaluated for pulmonary edema. Which cardiac condition is a common etiological factor for the development of pulmonary edema?

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.

A) Correct. Pink, frothy sputum, often described as "pink froth," is indicative of severe pulmonary edema with the presence of blood-tinged fluid in the alveoli.

B) Incorrect. A low-grade fever is not a typical sign of pulmonary edema and may indicate another underlying condition.

C) Incorrect. Clear breath sounds throughout the lung fields are not indicative of severe pulmonary edema, which often presents with crackles.

D) Incorrect. The absence of peripheral edema does not necessarily reflect the severity of pulmonary edema; it may be related to factors other than heart failure.
