Question: 1 / 400

Pink, frothy sputum is most characteristic of which condition?

Pulmonary embolism

Pulmonary edema

Pink, frothy sputum is most characteristic of pulmonary edema, which occurs when excess fluid accumulates in the lungs. This condition can arise from various causes, most commonly heart failure, where the heart is unable to pump effectively, leading to fluid leakage into the alveoli. The presence of blood mixed with the fluid gives the sputum a pink coloration, and the frothy nature is due to the type of fluid that is produced, which includes air bubbles mixed with fluid.

In cases of pulmonary edema, patients often present with symptoms such as shortness of breath, a feeling of suffocation, and the aforementioned pink, frothy sputum. This distinctive sputum serves as a critical clinical sign that helps differentiate pulmonary edema from other respiratory conditions.
