Answer to Question 1

ANS: C
The total CO2 represents the level of HCO3 in venous blood.

Answer to Question 2

ANS: A
The potassium level is of particular interest in the patient being weaned from mechanical ventila-tion, because both hyperkalemia and hypokalemia may render the diaphragm weak and less ef-fective.
