UAMS HEMATOLOGY STUDY GUIDE 5 2026
TEST PAPER QUESTIONS AND SOLUTIONS
GRADED A+
●● PT.
Answer: What is the extrinsic system tested by?
●● HMW kininogen and prekalikrein activate the extrinsic, whereas
exposed collagen that releases thromboplastin activates the intrinsic
pathway..
Answer: What activates the extrinsic pathway? What about the intrinsic
pathway?
●● PT and PTT.
Answer: What is the common system tested by?
●● 2, 7, 9, and 10.
Answer: What factors are associated with Factor K?
●● 1, 5, 8, 13, and 2.
Answer: What are the consumable factors?
,●● Hemostasis.
Answer: What is the process of keeping blood in the fluid state unless
clotting occurs due to vascular injury?
●● Primary hemostasis is the platelet plug formed on damaged vessels,
whereas secondary hemostasis is the fibrin formation from plasma
factors..
Answer: What is the difference between primary and secondary
hemostasis?
●● To form an endothelial layer and prevent RBCs from escaping. The
release of exposed substances such as collagen and Von Willebrands
factor causes a break in the system allowing RBCs to escape which
causing bleeding and bruising. Vasoconstriction occurs to stop the blood
flow..
Answer: What is the role of the vascular system? What causes a break in
this system? What puts a stop to this?
●● Bruising, petechiae, and mucous membrane bleeding.
Answer: What are the vascular disorder symptoms?
●● Inherited, often hereditary teleangiectasia and acquired, often from
drugs such as steroids, estrogen, or just from age.
Answer: What are the two categories for vascular disorder?
, ●● Megakaryocytes, produced in the bone marrow. It is the only cell that
gets bigger as it matures..
Answer: What is the parent cell to platelets and where is it produced?
What is unique about this cell?
●● Thrombopoietin and CSF.
Answer: What influences the number and size of megakaryocytes?
●● Endomitosis, megakaryocytes.
Answer: What is the doubling of DNA without cell division? What cell
does this?
●● When the filament extends through the endothelial cells and
fragments into the cells..
Answer: When do platelets get into the blood?
●● 2/3, the rest are stored in the spleen. If a splenectomy is performed,
the platelet count goes up. 8-12 days..
Answer: How many platelets circulate in the blood? Where are the rest
stored? What is the lifespan of platelets?
●● Platelet plasma membrane or peripheral zone - contains the
glycocalyx that is a receptor for various glycoproteins and
phospholipids.
