A. Poikilocytosis B. Anisocytosis C. Hypochromia D. Polychromasia (Answer: - A. Variation in shape of the erythrocytes on a peripheral blood smear is poikilocytosis. Anisocytosis refers to a change in size. Hypochromia is an increase in central pallor in erythrocytes. Polychromasia describes the bluish tinge of the immature erythrocytes (reticulocytes) circulating in the peripheral blood. Calculate the mean cell hemoglobin concentration (MCHC) using the following values: Hgb: 15 g/dL (150 g/L) Hct: 47 mL/dL (0.47) RBC: 4.50 × 106/μL (4.50 × 1012/L) A. 9.5% (.095) B. 10.4% (.104) C. 31.9% (.319) D. 33.3% (.333) (Answer: - C. MCHC is the average concentration of Hgb in red cells expressed as a percentage. It expresses the ratio of the weight of Hgb to the volume of erythrocytes and is calculated by dividing Hgb by the Hct, and then multiplying by 100. A decreased MCHC indicates that cells are hypochromic. In this example, (15 ÷ 47) × 100 = 31.9%. The reference range for MCHC is 32%-36%. A manual white blood cell (WBC) count was performed. A total of 36 cells were counted in all 9-mm^2 squares of a Neubauer-ruled hemacytometer. A 1:10 dilution was used. What is the WBC count? A. 0.4 × 10^9/L B. 2.5 × 10^9/L C. 4.0 × 10^9/L D. 8.0 × 10^9/L (Answer: - A. The formula used for calculating manual cell counts using a hemacytometer is: Number of cells counted × dilution factor × depth factor (10) divided by the area. In this example, 36 × 10 × 10 = 3600 ÷ 9 = 400/mm^3 or 0.4 × 10^9/L. When an erythrocyte containing iron granules is stained with Prussian blue, the cell is called a: A. Spherocyte B. Leptocyte C. Schistocyte D. Siderocyte (Answer: - D. Siderocytes are red cells containing iron granules and are visible when stained with Prussian blue.
