BSNC 3000 - Module 8: Perfusion &
Venous Thromboembolism Exam
Questions & Answers (Grade A+)
What is the breakdown word of hemostasis? -
correct answer ✅Stopping bleeding
What is the hemostasis? -
correct answer ✅Physiological process in response to vascular
injury in which platelets and fibrin form a clot to stop bleeding
What is required for effective hemostasis? -
correct answer ✅platelets (bone marrow function), clotting factors
(liver function), calcium, vitamin K
Why do we want to regulate clotting? -
correct answer ✅To prevent the clot from getting bigger or staying
too long during process
Why is effective and appropriate hemostasis an important
component of the physiological process for perfusion? -
correct answer ✅Inappropriate clotting can lead to
perfusion/blood flow being blocked or ineffective clotting can lead
to hypovolemia

Venous Thromboembolism Exam
Questions & Answers (Grade A+)
What can excessive hemostasis lead to? -
correct answer ✅Thrombosis
What can insufficient hemostasis lead to? -
correct answer ✅Bleeding
What does vascular injury cause? -
correct answer ✅Blood loss and exposes subendothelial collagen
What is step 1 of building a clot? -
correct answer ✅Platelet adhesion and activation
What are the steps of platelet adhesion and activation? -
correct answer ✅- blood vessels injury and vasoconstriction cause
a disturbance in laminar blood flow, and this allows platelets to
contact the blood vessel wall
- platelets have receptors that adhere to sub endothelial collagen
that is exposed due to vascular injury
- von willebrand factor (vWF) from endothelial cells bridges the
binding of platelets to collagen
- the adhesion of platelets to collagen stimulates platelet activation

Venous Thromboembolism Exam
Questions & Answers (Grade A+)
What happens to the shape of activated platelets? -
correct answer ✅Form cytoplasmic extensions that extend toward
other platelets
What is step 2 of the platelet plug? -
correct answer ✅Platelet aggregation and secretion
What are the steps of platelet aggregation and secretion? -
correct answer ✅- platelet activation causes a change in shape of
fibrinogen receptors exposing the binding site for fibrinogen
- activated platelets secrete substances stored in granules (calcium,
fibrinogen, ADP, vWF)
What does vWF do? -
correct answer ✅Assists in platelet adhesion
What does ADP do? -
correct answer ✅Binds to ADP receptors to activate and allow
aggregation
