Which sign indicates respiratory distress in pulmonary edema?

Which sign indicates respiratory distress in pulmonary edema?

• A. Nasal flaring and retractions
• B. Brisk capillary refill
• C. Clear breath sounds
• D. Normal respiratory rate

Answer: (A)

Pulmonary edema makes breathing work harder as fluid-filled alveoli stiffen the lungs and hinder gas exchange, so the body uses extra muscles to breathe. Nasal flaring and chest wall retractions are clear signs that the patient is pulling to get air in, reflecting this increased work of breathing and indicating respiratory distress. Brisk capillary refill points to perfusion status rather than breathing effort. Clear breath sounds are not typical in edema, where crackles may be heard, and a normal respiratory rate would not reflect distress. Therefore, nasal flaring with retractions best signals respiratory distress in pulmonary edema.
