1) The light-colored zone adjacent to the nucleus in a plasmacyte is the:
a. ribosome
b. chromatin
c. mitochondria
d. Golgi area
d (Morphological identifiable perinuclear halo.)
2) The majority of the iron in an adult is found as a constituent of:
a. hemoglobin
b. hemosiderin
c. myoglobin
d. transferrin
a (2/3 iron in body bound to Hgb.)
3) The main function of the hexose monophosphate shunt in the erythrocyte is to:
a. regulate the level of 2,3-DPG
b. provide reduced glutathione to prevent oxidation of hemoglobin
c. prevent the reduction of heme iron
,d. provide energy for membrane maintenance
b (Maintains in Fe++ form by way of reduced glutathione.)
4) In order for hemoglobin to combine reversibly with oxygen, the iron must be:
,a. complexed with haptoglobin
b. freely circulating in the cytoplasm
c. attached to transferrin
d. in the ferrous state
d (Functional form of Fe [reduced].)
5) In which of the following disease states are teardrop cells and abnormal
platelets most characteristically seen?
a. hemolytic anemia
b. multiple myeloma
c. G-6-PD deficiency
d. myeloid metaplasia
d (RBC morphology; disease state identification.)
6) In the normal adult, the spleen acts as a site for:
a. storage of RBCs
b. production of RBCs
c. synthesis of erythropoietin
d. removal of imperfect and aging cells
d (Major site of destruction of senescent red blood cells.)
, 7) After the removal of RBCs from the circulation hemoglobin is broken down into:
a. iron, prophyrin, amino acids
b. iron, protoporphyrin, globin
c. heme, protoporphyrin, amino acids
d. heme, hemosiderin, globin
b (Normal degradation products of red blood cells.)
8) Heinz bodies are:
a. readily identified with polychrome stains
b. rarely found in glucose-6-phosphate dehydrogenase deficient erythrocytes
c. closely associated with spherocytes
d. denatured hemoglobin inclusion that are readily removed by the spleen
d (Formed with oxidization of Fe and formation of methemoglobin.)
9) Cells for the transport of O2 and CO2 are:
a. erythrocytes
b. granulocytes
c. lymphocytes
d. thrombocytes
a (Primary functions of red blood cells.)
10) Erythropoietin acts as:
a. shorten the replication time of the granulocytes
b. stimulate RNA synthesis of erythroid cells
