Answer to Question 1

D
As cardiac output increases, less oxygen is extracted from the blood. Because of this, the C(a-v)O2 decreases and SvO2 increases. Increased cardiac output would also increase total oxygen delivery and decrease the oxygen extraction ratio.

Answer to Question 2

D
Alveolar consolidation, airway obstruction, mucus accumulation, and atelectasis are structural changes in the lungs associated with a myasthenia crisis.
