Which finding would indicate acute decompensated heart failure presenting with pulmonary edema?

• A. Fatigue, orthopnea, and dependent edema
• B. Severe dyspnea and blood-streaked, frothy sputum
• C. Temperature 100.4 F and pulse 102 beats/min
• D. Respirations 26 breaths/min despite oxygen by nasal cannula

Answer: (B)

Pulmonary edema from acute decompensated heart failure causes fluid to rapidly accumulate in the lungs, leading to sudden, severe shortness of breath and impaired gas exchange. A classic sign is severe dyspnea accompanied by blood-streaked, frothy sputum, which reflects fluid and red cells being expelled from edematous alveoli. This combination is the most specific indication of acute pulmonary edema in the setting of heart failure, because it directly shows the fluid overload in the lungs. While fatigue, orthopnea, and dependent edema can occur with chronic heart failure, they don’t capture the abrupt pulmonary congestion. A fever with tachycardia might point toward infection, and a higher respiratory rate on supplemental oxygen indicates distress but isn’t as diagnostic for pulmonary edema as the frothy, blood-tinged sputum pathognomonic sign.
