Which assessment finding is indicative of right-sided heart failure?

Jugular venous distension is a key indicator of right-sided heart failure. This condition occurs when the right side of the heart is unable to effectively pump blood to the lungs for oxygenation. As a result, blood can back up into the venous system, causing increased pressure in the veins, especially those in the neck, leading to visible distension.

In healthy individuals, the jugular veins should not be distended when they are sitting at a 45-degree angle; however, in the context of right-sided heart failure, elevated pressures cause the veins to visibly bulge. This is a particularly useful clinical sign for healthcare professionals when assessing a patient for heart failure, as it can indicate fluid overload and poor heart function.

Other findings such as frothy sputum (often associated with pulmonary edema), chest discomfort (which could relate to various cardiac conditions), and altered level of consciousness (which may arise from numerous causes, including severe hypoxia or low cardiac output) do not specifically point to right-sided heart failure as clearly as jugular venous distension does. Thus, this assessment finding is crucial for differentiating the particular type of heart failure being evaluated.
