A cell with an MCV of 69 fL is called:
Anisocyte
Normocyte
Macrocyte
Microcyte

Classify the cells with the following indices: MCV 106 fL, MCH 35, MCHC=33:
Macrocytic, Hypochromic
Macrocytic, Normochromic
Normocytic, Normochromic
Microcytic, Hypochromic

Which of the indices description best fit the following results? RBC count 3.0 x 1012/L; Hb 9 g/L; HCT 0.25L/L.
macrocytic, normocytic
microcytic, hypochromic
normocytic, normochromic
microcytic, normochromic

What is the RPI given the following? HCT 0.33 L/L, Retic count 10%.
A- 4.8
B- 3.7
C- 2.9
D- 9.0

Which of the following is a characteristic finding on the blood smear of a specimen that has a retic count of 21.5%?
Hypochromic macrocytes
Polychromatophilic macrocytes
Howell-Jolly bodies
Basophilic stippling

A patient with anemia has an RDW of 14.0 and an MCV of 120 fL. However, examination of the blood smear reveals significant anisocytosis. How do you explain these results?
The high MCV causes the falsely normal RDW
The instrument needs to be recalibrated
The MCV is falsely elevated
The RDW is only elevated if there is anisocytosis and a normal MCV

Upon review of a stained blood smear, you note that erythrocytes appear to form irregular clusters, like grapes. What CBC parameter of the following is unreliable based on this observation?
WBC count
Platelet count
Hemoglobin
MCV

A male patient has a Hb of 5.0 g/dL and a HCT of 0.14 L/L. His retic count is 25%. There are numerous polychromatophilic RBCs on the blood smear. How would you describe this patient’s BM response?
Hypoproliferative bone marrow response
Absent bone marrow response
Compensatory bone marrow response
Impaired erythropoietic response

Upon review of a stained blood smear, you note that most erythrocytes appear to be stacked on one another. What laboratory test should you look up on this patient to help verify that this is not an artifact?
Total protein
Haptoglobin
Vitamin B12
Serum iron

A 6-year-old patient has a Hb of 8.0 g/dL, RBC count 3.83 x 1012/L, HCT 0.25 L/L, RDW 15, PLT 156 x 109/L, WBC 10 x 109/L. What is the morphologic classification of this anemia?
Macrocytic
Microcytic hypochromic
Normocytic normochromic
Survival defect


What laboratory test should be done on the above patient to help determine the functional classification of the anemia?
Haptoglobin
Reticulocyte count
Bone marrow examination
Serum ferritin

A patient has the following results: Hb 9 g/dL, HCT 0.29 L/L, RBC count 2.6 x 1012/L, retic count 12%. What is the morphologic and functional classification of this anemia?
Normocytic, survival defect
Macrocytic, non-megaloblastic defect
Macrocytic, survival defect
Macrocytic, nuclear maturation defect

Which laboratory test is essential to determine if an anemia is due to hemolysis?
Serum ferritin
Reticulocyte count
Vitamin B12
RDW

A patient has a macrocytic anemia. A bone marrow aspirate is obtained and examined. The marrow is 60% cellular and the M:E ratio is 1: 2. These findings indicate:
Hypoplasia
Increased fat to cell ratio
Increased erythropoiesis
Dysplasia
