Answer to Question 1

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: The relationship between the CO2 production and the alveolar ventilation in terms of the alveolar partial pressure of CO2 is as follows:
CO2/ A  PACO2
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.

Answer to Question 2

ANS: A
A. Correct response: The PACO2 is linearly related to the CO2, and inversely related to the A. Therefore, doubling the CO2 doubles the PACO2. Similarly, doubling the A halves the PACO2.
B. Incorrect response: See explanation A.
C Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
