NR 507 Anemia (Questions with 100% correct answers)

Anemia correct answers _______ is a hematological disorder characterized by a reduction in the total number of circulating red blood cells (RBCs) and/or a decrease in hemoglobin (Hb) amount or function. Anemia can be caused by? correct answers 1) impaired RBC production, 2) excessive blood loss, 3) increased RBC destruction OR any combination of the three. Red Blood Cell (RBC) correct answers The number of erythrocytes in 1 cubic mm of whole blood. Normal for men is 4.7-6.1 mcL. Normal in women is 4.5-5.2 mcL. Hemoglobin (Hgb) correct answers The oxygen carrying pigment of red cells. Normal for men is 13.5-17.5 g/dL. Normal for women is 12.0-15.5 g/dL. Hematocrit (Hct) correct answers The volume of cells as a percentage of the total volume of cells and plasma in whole blood. Normal for women is 37-48%. Reticulocyte correct answers Immature RBCs. Used to assess bone marrow function. Normal in adults is approximately 3%. Mean Cell Volume (MCV) correct answers This measures the average size of the RBC. Normal is 80-100 fL. Mean Corpuscular Hemoglobin (MCH) correct answers Average weight of hemoglobin per red cell. Normal is 27-33 pg Mean Corpuscular Hemoglonin Concentration (MCHC) correct answers Average concentration of hemoglobin per erythrocyte. Normal is 32-36%. Red Cell Distribution Width correct answers The index of a quantitative estimate of the uniformity of individual cell size. Normal is 11.5-14.5% Anemia Classification correct answers Anemias can be classified into 3 categories based on the average size of the RBCs (MCV): Microcytic anemia (MCV<80 fL) describes RBCs that are small. Macrocytic anemia (MCV>100 fL) describes RBCs that are large. Normocytic anemia (MCV 80-99 fL) describes RBCs that are normal in size.
