A nurse is assessing a patient who has heart failure. Which of the following findings indicate worsening heart failure? (Select all that apply)

Choice A reason: Elevated CVP/right atrial pressure indicates right-sided heart failure, where the right ventricle fails to pump blood effectively, causing venous congestion. This increases pressure in systemic veins, reflecting fluid overload, a key sign of worsening heart failure, as it shows the heart’s inability to manage volume. Choice B reason: Decreased BNP is not associated with worsening heart failure. BNP rises in heart failure due to ventricular stretch from increased preload, signaling fluid overload. A decrease suggests improved cardiac function or treatment response, not exacerbation, making this an incorrect indicator of worsening condition. Choice C reason: Increased PAWP reflects left-sided heart failure, where left ventricular dysfunction causes fluid backup into the pulmonary circulation. Elevated pressure in the pulmonary veins and capillaries indicates pulmonary congestion, a critical sign of worsening heart failure, leading to symptoms like dyspnea and edema. Choice D reason: Decreased specific gravity suggests dilute urine, often from diuretic use in heart failure, not worsening. In worsening heart failure, reduced renal perfusion may increase specific gravity due to concentrated urine. This finding does not directly indicate heart failure exacerbation compared to CVP or PAWP.
