Answer to Question 1

ANS: D
The normal range for pulmonary artery occlusion pressure (PAOP) is 5-12 mm Hg. Mitral valve stenosis is the cause of an abnormally high PAOP. Therefore the value of 20 mm Hg is the cor-rect answer.

Answer to Question 2

ANS: B
The normal range for pulmonary artery occlusion pressure (PAOP) is 5-12 mm Hg, for central venous pressure (CVP) 2-6 mm Hg, for pulmonary artery pressure (PAP) 15-35/5-15 mm Hg, and for mean arterial pressure (MAP) 70-100 mm Hg. Right heart failure causes the CVP to increase significantly. Answer B shows a CVP that is greatly increased and is therefore indicative of right heart failure.
