Which condition is most likely to present with pink, frothy sputum?

• A. Pneumonia
• B. COPD
• C. Asthma attack
• D. Pulmonary Edema

Answer: (D)

Pink, frothy sputum points to fluid filling the alveoli and airways in the lungs, a hallmark of pulmonary edema. When excess fluid accumulates in the lungs—often from left-sided heart failure or fluid overload—the fluid mixes with air and red cells as it is coughed up, creating a foamy, pink appearance. This sign often accompanies shortness of breath and crackles on exam, reflecting fluid in the lungs. Pneumonia can cause a productive cough with colored mucus, but it’s not typically described as pink and frothy. COPD usually involves chronic mucus production and coughing, not this pink frothy sputum. An asthma attack produces wheezing and airway constriction with mucus, but pink frothy sputum is not characteristic. So the presence of pink, frothy sputum most strongly points to pulmonary edema.
