Answer to Question 1

ANS: C
Polycythemia increases the blood viscosity, which makes it more difficult for the heart to pump the blood, resulting in an increase in systemic vascular resistance. Moderate hypoxemia, hydrala-zine, and nitroglycerin all reduce systemic vascular resistance.

Answer to Question 2

ANS: A
The pulmonary vascular resistance can increase significantly during periods of alveolar hypoxia.
