A 29-year-old woman was found to have a hemoglobin level of 7.8 mg/dl, with a reticulocyte count of 0.8%. The peripheral blood smear showed microcytic hypochromic anemia. On high-performance liquid chromatography (HPLC), hemoglobin A2 and hemoglobin F were 2.4% and 1.3%, respectively. The serum iron and total iron-binding capacity (TIBC) were 15 mg/dl and 420 micrograms per deciliter, respectively. What is the most likely cause of anemia in this patient?
AIron deficiency anemia
BBeta thalassemia minor
CSideroblastic anemia
DAnemia due to chronic infection
Which of the following statements is true regarding anemia of prematurity?
ALow reticulocyte response
BHemoglobin level <10 gm/dL
C10 ml/kg packed cell transfusion
DMicrocytic hypochromic type
All of the following are characteristic features of treatment of iron deficiency anemia with oral iron supplements, except which of the following?
ABioavailability is enhanced with vitamin C
BThe proportion of iron absorbed reduces as hemoglobin improves
CThe reticulocyte count should begin to increase within 7-10 days and peak at 2-4 weeks; this suggests good response to treatment
DThe treatment should be discontinued immediately once hemoglobin normalizes to prevent side effects of iron
