Which condition is NOT a sign of fluid overload requiring diuretic use?

High blood pressure is not a direct sign of fluid overload requiring diuretic use in the context of heart failure. While it is true that fluid overload can contribute to elevated blood pressure, it does not specifically indicate that diuretics are immediately necessary.

In heart failure, fluid overload leads to symptoms like shortness of breath due to pulmonary congestion, peripheral edema as excess fluid accumulates in the tissues, and signs like a pulsatile liver which may reflect increased venous pressure. These conditions are more direct indicators of excess fluid retention and can signal the need for diuretics to help remove the excess fluid from the body, alleviating the pressure on the heart and lungs.
