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
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. Skin temperature and color can provide important clues about tissue perfusion and oxygenation, which are critical in pulmonary edema.
B) Incorrect. While urinary output is important, it is not the primary focus when monitoring respiratory status in pulmonary edema.
C) Incorrect. Bowel sounds are unrelated to pulmonary edema and should not be the priority assessment.
D) Incorrect. Peripheral edema may be a sign of fluid retention, but skin color and temperature are more directly related to respiratory status.
Correct Answer is B
Explanation
A) Incorrect. A decreased respiratory rate is not typically associated with pulmonary edema, which often leads to increased respiratory effort.
B) Correct. Inspiratory crackles in the lung bases are indicative of fluid accumulation in the alveoli and are a common physical finding in pulmonary edema.
C) Incorrect. Increased breath sounds are not typically associated with pulmonary edema; instead, crackles or wheezing may be heard.
D) Incorrect. Diminished heart sounds are not a characteristic finding in pulmonary edema.
