Which symptom is most characteristic of pulmonary edema?

• A. Dyspnea
• B. Fever
• C. Rash
• D. Syncope

Answer: (A)

Pulmonary edema causes fluid to accumulate in the alveoli and interstitial spaces, which hinders gas exchange and leads to shortness of breath. The most characteristic symptom is dyspnea, often with rapid breathing and exertional or resting difficulty, and it can progress to hypoxemia. You may also hear crackles on lung auscultation and, in more severe cases, see pink frothy sputum as fluid shifts into the airways. Fever would point toward infection, rash toward an inflammatory or allergic process, and syncope is not a primary feature of edema. In pregnancy, recognizing dyspnea as a sign of fluid overload is especially important because it could indicate pulmonary edema related to conditions like preeclampsia or volume overload.
