Answer to Question 1

ANS: A
Any process in which alveolar ventilation fails to eliminate CO2 as rapidly as the body produces it causes respiratory acidosis. This could occur in different ways. A person's ventilation may be decreased from a drug-induced central nervous system depression.

Answer to Question 2

ANS: B
If hypercapnia is uncompensated, respiratory acidosis occurs with a low pH, a high PaCO2, and a normal or slightly high HCO3. In this instance, the slightly high HCO3 is not a sign that the kidneys have started compensatory activity; it merely reflects the effect of CO2 hydration reac-tion on HCO3.
