Which description is consistent with acute lymphocytic
leukemia (ALL)?
a. ALL is a progressive neoplasm defined by the presence of
greater than 30%lymphoblasts in the bone marrow or blood.
b. Leukocytosis and a predominance of blast cells
characterize the bone marrow and peripheral blood. As the
immature blasts increase, they replace normal myelocytic
cells, megakaryocytes, and erythrocytes.
c. B cells fail to mature into plasma cells that synthesize
immunoglobulins.
d. The translocation of genetic material from genes 9 and 22
create an abnormal,fused gene identified as BCR-ABL. -
...ANSWER...a
RATIONALE: ALL is a progressive neoplasm defined by
the presence of greater than 30% lymphoblasts in the bone
marrow or blood. None of the other options provide an
accurate description of ALL.
Which description is consistent with chronic myelogenous
leukemia (CML)?
a. Defects exist in the ras oncogene, TP53 tumor-suppressor
gene, and INK4A, the gene encoding a cell-cycle regulatory
protein.
b. Leukocytosis and a predominance of blast cells
characterize the bone marrow and peripheral blood. As the
immature blasts increase, they replace normal
myelocyticcells, megakaryocytes, and erythrocytes.
c. B cells fail to mature into plasma cells that synthesize
immunoglobulins.
d. The translocation of genetic material from genes 9 and 22
creates an abnormal,fused protein identified as BCR-ABL1.
- ...ANSWER...ANS: D
RATIONALE: The Philadelphia chromosome is present in
more than 95% of those with CML, and the presence of the
BCR-ABL1 protein is responsible for the initiation of CML.
The other options do not accurately describe CML.
Which description is consistent with chronic lymphocytic
leukemia (CLL)?
a. Defects exist in the ras oncogene, TP53 tumor-suppressor
gene, and INK4A, thegene encoding a cell-cycle regulatory
protein.
b. Leukocytosis and a predominance of blast cells
characterize the bone marrow andperipheral blood. As the
immature blasts increase, they replace normal
myelocyticcells, megakaryocytes, and erythrocytes.
c. B cells fail to mature into plasma cells that synthesize
immunoglobulins.
d. The translocation of genetic material from genes 9 and 22
creates an abnormal,fused protein identified as BCR-ABL. -
...ANSWER...c
RATIONALE: CLL is derived from transformation of a
partially mature B cell that has not yet encountered antigen.
The other options do not accurately describe CLL.
Which term is used to describe a red-purple discoloration
caused by diffuse hemorrhage into the skin tissue?
a. Petechiae
b. Hematoma
c. Ecchymosis
d. Purpura - ...ANSWER...ANS: D
RATIONALE: Diffuse hemorrhage into skin tissues that is
visible through the skin causes a red-purple discoloration
identified as a purpura. None of the other options are used to
identify this symptom.
Immune thrombocytopenia (ITP) is a(n) condition in adults
and a(n) condition in children.
a. Acute; acute
b. Chronic; chronic
c. Acute; chronic
d. Chronic; acute - ..
