A patient with tricuspid valve stenosis is experiencing systemic edema and jugular vein distension. Which nursing intervention is most crucial?

Tricuspid valve stenosis causes impaired right atrial emptying, leading to right atrial pressure elevation, systemic venous congestion, jugular venous distension, hepatomegaly, and peripheral edema. Reduced forward flow results in fluid accumulation in dependent tissues and progressive volume overload. Rationale: A. Increasing fluid intake worsens venous congestion by expanding intravascular volume. In tricuspid stenosis, right-sided filling is already impaired. This intervention increases preload burden and exacerbates systemic edema and jugular venous distension. B. Frequent ambulation may assist circulation in some conditions but does not address fixed valvular obstruction. Excess activity can increase cardiac demand. This does not correct right atrial pressure elevation or fluid retention. C. Potassium supplementation is not indicated unless hypokalemia is documented. It does not influence valvular obstruction or venous congestion. This intervention does not address fluid overload or systemic edema. D. Daily weight monitoring provides the most sensitive and objective indicator of fluid status changes. It allows early detection of worsening systemic congestion. This is crucial for assessing progression of volume overload in tricuspid stenosis.
