Answer to Question 1

ANS: D
The final O2 content, also arrived at by averaging the high and low / points, is shown as point X on the O2 curve (Figure 12-20). Whereas the averaged value for carbon dioxide was normal, the PaO2 resulting from averaging the O2 content of the high and low / units is well below normal (point a on the O2 curve of Figure 12-20).

Answer to Question 2

ANS: C
imbalances have a greater effect on oxygenation than on carbon dioxide removal.
