A client with pulmonary edema is receiving oxygen therapy. What should the nurse assess to ensure the client's oxygenation needs are met effectively?

A) Incorrect. Nausea and vomiting are not typically associated with pulmonary edema.

B) Correct. Orthopnea, or difficulty breathing when lying flat, is a common symptom of pulmonary edema related to heart failure.

C) Incorrect. While sweating and diaphoresis can occur in response to respiratory distress, they are not specific to pulmonary edema.

D) Incorrect. Sharp, stabbing chest pain is not a common manifestation of pulmonary edema but may occur with other cardiac or respiratory conditions.

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.
