Hematology exam 4 MLT-MLS UAMS UPDATED ACTUAL Questions and
CORRECT Answers
How can a blast be differentiated from a Nuclear Chromatin clumping
lymph?
Which cell is usually seen in viral Reactive Lymphocyte
infections?
Which cell is seen in parasitic infections? Eosinophils
Are plasma cells normally seen in nope
peripheral blood?
What happens to hematocrit if a patient is Increase
dehydrated?
If you notice 3 NRBCs on a newborn normal (ref: 0-20)
peripheral smear, is this normal or
abnormal?
If you notice 3 NRBCs on an adult abnormal (ref: 0-5, should always include in count)
peripheral smear, is this normal or
abnormal?
Are 60% lymphs found on a 6 month old normal
peripheral smear considered normal?
Are 3% Blasts found in the peripheral abnormal
blood of a newborn normal?
Are 3% blasts found on the peripheral abnormal
blood of an adult considered normal or
abnormal?
What may be seen in the blasts of AML? auer rods
Should Plasma cells be found in the Not in a healthy patient. You will see these in: BM, lymph nodes, spleen unless
peripheral blood? patient has MM.
What is the expected platelet count on a Approximately 10,000/µL (incredibly low)
patient with chemotherapy?
, What is the platelet count of a patient with >1,000,000/µL
essential thrombocythemia?
increase in neutrophils
Neutrophilia Associated with bacterial infections, stress, tissue necrosis, inflammation and
malignancies
decrease in neutrophils
Neutropenia
Associated with leukemia, chemotherapy, aplastic anemia, or infection
increase in eosinophils
Eosinophilia
Associated with allergies, parasitic infections, some leukemias
increase in basophils
Basophilia
Associated with CML and other myeloproliferative disorders
increase in monocytes
Monocytosis
Associated with leukemias, bacterial infections, and rickettsial infections
What morphological anomaly is this leukocyte
displaying?
Toxic granulation
What morphological anomaly is this leukocyte
displaying?
Dhole bodies
What morphological anomaly is this leukocyte
displaying?
Vacuoles
Very serious condition (probably will die before
adulthood)
Autosomal recessive
-Will turn into anime character (albinism, melanin
affected)
Chediak-Higashi Recurrent pyrogenic infections
Cells contain huge, fused lysosomes that can't kill
bacteria
Large inclusions will be seen in granulated cells
Neutropenia present because many jacked up
cells won't even leave the bone marrow
What would you find in a PBS of a patient Tear drop-shaped rbc, Large bizarre plts, Micromegakaryocytes
with primary myelofibrosis?
A patient has a platelet count of 700 x 10^3 Essential thrombocythemia
per microliter, with abnormalities in size,
shape, granularity of platelets; a wbc # of
12x10^3 per microliter, and hgb of 11g/dL.
The philadelphia chromosome is not
present. What is the likely diagnosis?
