A nurse is explaining the pathophysiology of pulmonary edema to a group of nursing students. Which physiological mechanism underlies the development of pulmonary edema?

Increased lung compliance

Impaired alveolar fluid clearance

Constricted pulmonary blood vessels

Enhanced left ventricular contractility

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

A) Correct. Atrial fibrillation is a cardiac arrhythmia that can lead to heart failure, which is a common etiological factor for pulmonary edema.

B) Incorrect. Hypothyroidism is not typically a direct cause of pulmonary edema.

C) Incorrect. While COPD can lead to respiratory-related symptoms, it is not a direct cause of pulmonary edema.

D) Incorrect. Rheumatoid arthritis is not a known cause of pulmonary edema.

A. High-sodium diet to maintain blood pressure B. Low-potassium diet to prevent electrolyte imbalances C. Low-sodium diet to reduce fluid retention D. High-protein diet to promote muscle strength

Correct Answer is C

Explanation

A) Incorrect. A high-sodium diet is not recommended for clients with pulmonary edema, as it can exacerbate fluid retention.

B) Incorrect. Low-potassium diets are not typically recommended for clients with pulmonary edema, as potassium is important for heart and muscle function.

C) Correct. A low-sodium diet is essential to reduce fluid retention and manage pulmonary edema.

D) Incorrect. While adequate protein intake is important for overall health, it is not the primary dietary concern in pulmonary edema.
