1. In a case of Acute Lymphoblastic Leukemia, the lymphoblasts demonstrated strong
localized positivity with acid phosphatase.
The cells were positive for CD2 and CD7 and negative for CD19, CD24, and CD20.
These blasts are most likely :
(A) Lymphoid stem cells ൯ T lymphoblasts
(0) 8 lymphoblasts மு) Undifferentiated blasts

2. A patient with anemia of chronic disease is most likely to have which set of laboratory
test results ?
(A) MCV decreased, serum iron decreased, serum ferritin decreased, TIBC and %
saturation decreased
(B) MCV normal, serum iron increased, serum ferritin decreased, TIBC and %
saturation decreased
(C) MCV normal, serum iron decreased, serum ferritin increased, TIBC and %
saturation decreased
(0) MCV decreased, serum iron increased, serum ferritin increased, TIBC and %
saturation increased

8. An increase in the reticulocyte count is accompanied by :
(A) Suppressed maturation of normoblasts in the bone marrow
(B) A shift to the left in the oxygen dissociation curve
(0) Polychromasia on the Romanovsky stained blood smear
(D) An increase in direct serum bilirubin

4. A 8-year-old boy presents with intramuscular hematomas and recurrent hemarthroses.
Laboratory tests reveal normal platelet count bleeding time, and PT, but the PTT is
prolonged. This condition most likely results from an abnormality involving :

(A) Chromosome 8 (B) Chromosome 14
(C) Chromosome 21 (D) X Chromosome

5. A patient is suspected of having hemolytic anemia. Numerous spherocytes are present
in the blood smear, and the reticulocyte count is 18%. What test should be done to
determine whether this is an autoimmune process ?

(A) Direct Antiglobulin Test (DAT) (B) Osmotic Fragility Test
(C) Urinalysis (D) Serum Bilirubin

6. 4 joint aspiration is performed on a 60 year old lady with painful swollen elbow, and a
sample is sent to the laboratory. A cytocentrifuged slide is examined with polarized
light shows needlelike intracellular and extracellular crystals which exhibit negative
birefringence compensator. These crystals would be best identified as which of the

following ?
(A) Calcium pyrophosphate (B) Cholesterol
(0) Monosodium urate (D) Steroids
