Week 6 Content quiz
Question 1
What is the role of thromboxane A (TXA2) in the secretion stage of
hemostasis?
Stimulates the synthesis of serotonin.
Promotes vasodilation.
Stimulates platelet aggregation.
Promotes formation of cyclooxygenase.
Question 2
What does the student learn about erythrocytes?
Erythrocytes contain a nucleus, mitochondria, and ribosomes.
Erythrocytes synthesize proteins.
Erythrocytes have the ability to change shape to squeeze through
microcirculation.
Erythrocytes are more abundant in women than men.
Question 3
What is the fundamental physiologic manifestation of anemia?
Hypotension
Hyperesthesia
Hypoxia
Ischemia
Question 4
A patient has been diagnosed with acute lymphocytic leukemia (ALL) and
asks the healthcare professional to describe it. What description by the
professional is most accurate?
, ALL is a progressive neoplasm defined by the presence of greater
than 30%
lymphoblasts in the bone marrow or blood.
In ALL, immature blasts cells replace normal myelocytic cells,
megakaryocytes,
and erythrocytes.
B cells fail to mature into plasma cells that synthesize immunoglobulins.
The translocation of genetic material from genes 9 and 22 create an
abnormal,
fused gene identified as BCR-ABL.
Question 5
What is the life span of an erythrocyte (in days)?
20 to 30
60 to 90
100 to 120
200 to 240
Question 6 point
What term is used to describe the capacity of some erythrocytes to
vary in size, especially in relationship to some anemias?
Poikilocytosis
Isocytosis
Anisocytosis
Microcytosis
Question 7 point
What does the student learn about the role of collagen in the clotting
process?
Initiates the clotting cascade
Activates platelets
Stimulates fibrin
