During the assessment of a client the nurse finds jugular venous distention (JVD) with the head of the bed elevated 45 degrees and an enlarged liver upon palpation. The nurse interprets that these findings may indicate:

A. JVD is usually a sign of systemic venous congestion rather than a localized blockage in the jugular vein. B. Right-sided heart failure causes blood to back up into systemic circulation, leading to JVD and hepatomegaly due to liver congestion. C. Slight decrease in cardiac output does not typically cause visible JVD and liver enlargement. D. Decreased tissue perfusion is a general term and does not specifically explain JVD and enlarged liver findings.
