A 70-kg male patient has a CO2 of 200 ml/min and a VA of 9 L/min. From this information, what can you infer?
 
  a. The patient's carbon dioxide production is abnormally low.
  b. The patient's A is abnormally low.
  c. The patient will have a lower than normal PACO2.
  d. The patient will have a higher than normal PACO2.

Question 2

The lowest PO2 would normally be found in what location?
 
  a. Arterial blood
  b. Atmospheric air
  c. Cells
  d. Venous blood

Answer to Question 1

ANS: C
When the CO2 is normal while the A is elevated, the PACO2 must be lower than normal. Like-wise, the PACO2 will fall if carbon dioxide production decreases or alveolar ventilation increases.

Answer to Question 2

ANS: C
The intracellular PO2 (approximately 5 mm Hg) provides the final gradient for oxygen (O2) diffu-sion into the cell.
