Select and explain. 
A. Tricuspid regurgitation, B. Right hea failure, C. Decreased after load, D. PS
C: Decreased after load
Answer: C: Decreased after load 
Explanation: Answer is C (Decreased after load) Hepatojugular reflux results from an increase in preload and afterload to the right atrium and ventricle (and not by a decrease in after load). Hepatojugular reflux is a characteristic feature of Right ventricular, failure. Tricuspid regurgitation and Puhnonic stenosis are both causes of right ventricular failure and may hence produce a positive hepatojugular reflux.
