The findings associated with right heart failure typically include an increase in central venous pressure (CVP), due to the inability of the right heart to effectively pump blood into the pulmonary circulation. This stagnation of blood leads to a backlog, which can raise the pressure in the right atrium and subsequently the CVP.

In right heart failure, the pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) may appear normal or even decreased because the left side of the heart is functioning adequately, allowing for normal pressures in the pulmonary circulation, assuming there is no left-sided heart failure concurrently affecting those readings. Moreover, cardiac output can remain within the normal range for a time, as the body may adapt to the conditions up to a certain point.

The correct answer reflects these typical pressure changes seen in right heart failure, showcasing the relationship between CVP and the pressures in the pulmonary artery and capillary wedge. The other choices do not align with these common physiological responses observed in patients with right heart failure.
