HEMATOLOGY: Chapter 1; Rodak's
Romanowsky-type stains - Correct answer-polychromatic, stain more than 1 color, a
mixture of acidic and basic dyes
Morphology - Correct answer-scientific term for cell appearance
plasma and formed elements - Correct answer-What are the two main components of
blood?
92% water, 7% plasma proteins, 1% other solutes - Correct answer-Plasma
Composition
Albumin - Correct answer-protein in blood; maintains the proper amount of water in the
blood and osmolarity. Transport substances
Globulins - Correct answer-Plasma antibodies
Fibrinogen - Correct answer-A blood protein essential to blood clotting. The conversion
of fibrinogen to its active form (fibrin) is among the final steps in clot formation, and is
triggered by thrombin.
Erythrocyte - Correct answer-appears pink to red and measures 6-8 micrometer in
diameter with a zone of pallor at the center
zone of pallor - Correct answer-occupies 1/3 of RBC center
Anemia - Correct answer-A condition in which the blood is deficient in red blood cells, in
hemoglobin, or in total volume. Means loss of oxygen-carrying capacity
Polycythemia - Correct answer-A disorder characterized by an abnormal increase in the
number of red blood cells in the blood
5 l - Correct answer-How much blood does the average adult have?
hematology - Correct answer-study of blood and blood forming tissues
Erythrocyte, Leukocyte, Thrombocyte - Correct answer-the 3 categories of blood cells
Athanasius Kircher - Correct answer-Described "worms" in blood
, Anton van Leeuwenhoek - Correct answer-Invented the microscope, fave the first
account of RBCs
Giulio Bizzozero - Correct answer-First coined "petites plaques"
0.85% normal saline - Correct answer-mixed with blood for testing; matches the
osmolality of blood that prevents cell swelling or shrinking
1:200 - Correct answer-A typical dilution for RBC counting
Hematocytometer - Correct answer-device for counting blood cells microscopically
microliter, milliliter, liter - Correct answer-units in reporting RBC count
Coulter counter - Correct answer-The first electronic counter; electronically scans a fluid
as it passes through a tiny pipette
RBC count, HGB, HCT - Correct answer-3 numerical results used to compute RBC
indices
Mean Cell Volume - Correct answer-recorded in femtoliters, reflects RBC diameter on a
Wright-stained blood
Mean Cell Hemoglobin Concentration (MCHC) - Correct answer-expressed in g/dL,
reflects RBC staining intensity and amount of central pallor
Mean Cell Hemoglobin (MCH) - Correct answer-expressed in picograms, expresses the
mass of hemoglobin and parallels the MCHC
RBC distribution width (RDW) - Correct answer-expresses degree of variation of RBC
size in RBC volume
anisocytosis - Correct answer-presence of red blood cells of unequal size
RBC count, HGB, HCT, indices, morphology - Correct answer-parameters employed to
detect, diagnose, assess the severity and monitor treatment of anemia, polycythemia
and other conditions that affect RBCs
polychromatic erythrocyte - Correct answer-1. Polychromatic erythrocytes have a faintly
blue or purple coloring
2. Larger than normal RBC
3. stains slightly blue-gray
4. Reticulocyte stage*
