Answer to Question 1

ANS: D
Oxygen transport depends on both the number of circulating RBCs and the amount of normal hemoglobin in the cell. This explains why polycythemia (increase in the number of erythrocytes) occurs in conditions characterized by prolonged tissue hypoxia, such as cyanotic heart defects. Dehydration, severe infections, or immunosuppression will not precipitate polycythemia.

Answer to Question 2

ANS: D
Passive range of motion exercises should never be part of an exercise regimen after an acute episode because the joint capsule could easily be stretched and bleeding could recur. Active range of motion exercises are best so that the patient can gauge his or her own pain tolerance. The child can ambulate to the playroom or the cafeteria.
