Answer to Question 1

ANS: A, B, C
Causes of microcytic hypochromic anemia are decreased erythrocyte life span, failure of mecha-nisms of compensatory erythropoiesis, or disturbance of the iron cycle. Increased metabolic rate and swelling of tissues does not lead to anemia.

At the time of diagnosis, the individual commonly presents with the classic group of symptoms: fever, sore throat, cervical lymph node enlargement, and fatigue; generalized lymph node en-largement also may develop, as well as enlargement of the spleen and liver.
