While assessing a patient with ascites, the nurse notes jugular venous distention with the head of the bed at 45 degrees. This finding indicates:

• A. Decreased fluid volume
• B. Jugular vein atherosclerosis
• C. Increased right atrial pressure
• D. Incompetent jugular vein values

Answer: (C)

Jugular venous distention is a sign of elevated central venous pressure, reflecting increased right atrial pressure. When the patient’s head is elevated to 45 degrees, observing a distended jugular vein indicates that the right atrial pressure is high, meaning there is venous congestion. In the context of ascites, this pattern commonly points to right-sided heart failure or systemic venous congestion, where blood backs up into the venous system. So the finding best indicates increased right atrial pressure.

This isn’t due to decreased fluid volume, which would lower venous pressure, nor is it due to jugular vein atherosclerosis or valve incompetence in this acute context.
