Which of the following will cause an increase in systemic vascular resistance?
 
  a. Hydralazine c. Polycythemia
  b. Nitroglycerin d. Moderate hypox-emia

Question 2

Which of the following can increase pulmonary vascular resistance?
 
  a. Alveolar hypoxia c. Decreased para-sympathetic tone
  b. Moderate hypox-emia d. Recruitment of pulmonary vessels

[Ahernandez18]

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.
