Answer to Question 1

ANS: 4, 5, 6
Three things influence the capacity of the blood to carry oxygen: the amount of dissolved oxygen in the plasma, the amount of hemoglobin, and the tendency of hemoglobin to bind with oxygen. The remaining options are not directly involved.

Answer to Question 2

ANS: 2, 3, 5, 6
Clinical findings of left-sided heart failure include crackles on auscultation, hypoxia, shortness of breath on exertion and often at rest, cough, and paroxysmal nocturnal dyspnea. The remaining options are more reflective of right-sided failure.
