Answer to Question 1

ANS: D
In aplastic anemia, erythrocyte stem cells are underdeveloped, defective, or absent; iron is not deficient, there are no excess levels of erythropoietin, nor do cells undergo hemolysis.

Answer to Question 2

ANS: B
The rate and depth of breathing increase in an effort to increase oxygen availability accompanied by an increase in the release of oxygen from hemoglobin. Bronchodilation occurs, not con-striction. Dyspnea is not a compensatory mechanism but a side effect of the body's attempt to increase oxygen. The respiratory system does not activate the renin-angiotensin response; the kidneys are involved.
