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?
Complete blood count (CBC)
Electrocardiogram (ECG)
Chest X-ray
Urinalysis
The Correct Answer is C
A) Incorrect. While a complete blood count (CBC) may provide some information, it is not the primary diagnostic test for pulmonary edema.
B) Incorrect. An electrocardiogram (ECG) may be used to evaluate cardiac function but does not directly assess pulmonary edema.
C) Correct. A chest X-ray is a key diagnostic tool for assessing the presence, severity, and underlying causes of pulmonary edema by visualizing lung and heart structures.

Correct Answer is B
Explanation
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.
