Answer to Question 1

ANS: C
An enlarged liver is called hepatomegaly and may be caused by right-sided heart failure from chronic hypoxemia (cor pulmonale), although many other causes exist.

Answer to Question 2

ANS: A
Pulmonary hyperinflation, pleural effusion, pneumothorax, and obesity make identification of both S1 and S2 difficult. The intensity of S1 and S2 also decreases when the force of ventricular contraction is poor, as in heart failure, or when valvular abnormalities exist.
