Which condition will cause increase in bone marrow production of neutrophils resulting to neutrophils?
a. Strenuous exercise
b. Pregnant woman in labor
c. Acute infection
d. Tachycardia
c. Acute infection
Which finding is not consistent with leukemoid reaction?
a. Absence of eosinophils
b. LAP score of more than 100

The following are performed to determine the LAP score, except:
a. 100 neutrophils are counted
b. Grading the staining reaction from 0-4+
c. Band forms are also counted to complete 100 cells
d. None of the choice

Severe chronic neutropenia is defined as
a. Agranulocytosis for at least 6 months
b. Neutrophil count of <2 x 10^9/L for 1 month
c. Neutrophil count of <2 x 10^9/L for at least 6 Months
d. None of these
a. Agranulocytosis for at least 6 months
Frequently this is the first sign of recovery from an acute overwhelming infection with agranulocytosis
a. Absolute monocytosis
b. Relative monocytosis
c. Toxic granules
d. Absolute count of < 1.1 x 10^9/L
b. Relative monocytosis
Lymphocytosis with morphologic alteration will be seen in the following cases except in
a. Infectious mononucleosis
b. Viral influenza
c. Pertussis
d. CMV Infection
c. Pertussis
Eosinophils may be seen in the following cases except in
a. CML
b. Parasitic infection
c. Allergic conditions
d. None of these
d. None of these
A patient who is on steroid therapy will have
a. Monocytopenia
b. Lymphocytosis
c. Monocytosis
d. B and C
a. Monocytopenia
Small, oval, pale blue structures that are peripherally located in the cytoplasm and seen only in neutrophils are most probably
a. Dohle inclusion bodies
b. Inclusions in May-hegglin anomaly
c. Phagocytic vacuoles
d. Autophagocytic vacuoles
a. Dohle inclusion bodies
True of toxic granulations except:
a. They are peroxidase positive
b. Inversely proportional to CRP level
c. Seen also in band form and metamyelocytes
d. Should be differentiated from Reiley bodies
b. Inversely proportional to CRP level

a. Mild left shift
b. Moderate left shift
c. Marked left shift
d. No left shift
c. Marked left shift
Vacuoles in neutrophils that are formed due to effect of EDTA are
a. Smaller than phagocytic vacuoles
b. Usually 6 um in size
c. Formed only in patients with spesis d. None of these
a. Smaller than phagocytic vacuoles
Reactive lymphocytes appear with increased basophilia of the cytoplasm due to:
a. Increased cytoplasmic RNA
b. Engulfed bacteria in the cytoplasm
c. Defective fusion of phagosome and lysosome
d. None of these
a. Increased cytoplasmic RNA
Pince nez appearance in Pelger_huet anomaly is due to mutation in:
a. LYST gene
b. Lamin B receptor gene
c. NADPH oxidase gene
d. IL-2 receptor gene
b. Lamin B receptor gene
Which finding will favor Pelger-Huet anomaly over other conditions that will cause neutrophils to have pince-nez appearance?
a. >20% of neutrophils are with bilobed
b. >80% of neutrophils are with bilobed nuclei
c. <50% of neutrophils are with bilobed nuclei
d. >40% of neutrophils are with bilobed nuclei
b. >80% of neutrophils are with bilobed nuclei
