Answer to Question 1

ANS: A
Perfusion relates to the ability of the blood to deliver oxygen to the cellular level and return the carbon dioxide to the lung for removal. COPD and asthma are examples of a ventilation problem. Severe anemia is an example of a transport problem of gas exchange.

Answer to Question 2

ANS: A
Respiratory acidosis is caused by an increase in retention of carbon dioxide, regardless of the underlying disease. A decrease in carbon dioxide retention may lead to respiratory alkalosis. An increase in production of lactic acid leads to metabolic acidosis. Removal of an acid (gastric secretions) will lead to a metabolic alkalosis.
