Under what conditions will the alveolar PACO2 rise above normal?
 
  a. If both metabolic rate and ventilation in-crease (e.g., through exercise)
  b. If carbon dioxide production decreases relative to VA
  c. If VA decreases relative to carbon dioxide production
  d. When the patient is febrile

Question 2

What is the approximate normal level of carbon dioxide production (CO2) for an adult?
 
  a. 200 ml/min
  b. 250 ml/min
  c. 4200 ml/min
  d. 6000 ml/min

[Qarqy]

Answer to Question 1

ANS: C
The PACO2 will increase above this level if carbon dioxide production increases while alveolar ventilation remains constant or when alveolar ventilation decreases while CO2 remains constant.

Answer to Question 2

ANS: A
In a healthy individual the normal CO2 of is approximately 200 ml/min.
