So-called heart failure cells found in sputum are caused by:
A) Right ventricular failure
B) Left ventricular failure
C) Cardiac hemorrhage
D) Aortic hemorrhage
E) Cyanosis

Question

Quizplus · Accepted Answer

Heart failure cells, also known as hemosiderin-laden macrophages, are typically found in the sputum of patients with left ventricular failure. These cells result from the accumulation of hemoglobin breakdown products in lung tissue due to the congestion and increased pressure caused by the heart's failure to effectively pump blood out of the left ventricle. Right ventricular failure and cardiac or aortic hemorrhage are not typically associated with the presence of heart failure cells in sputum, and cyanosis is a clinical sign of oxygen deprivation that may be present in heart failure but is not directly related to the formation of heart failure cells.
