,### Question 1 cf cf




The coagulation cascade involves each of the following except:
cf cf cf cf cf cf cf cf




- Make thrombocytes
cf cf




Verified Explanation: cf cf cf




The coagulation cascade is responsible for the conversion of soluble plasma proteins into
cf cf cf cf cf cf cf cf cf cf cf cf




cf an insoluble fibrin clot. It includes activation of intrinsic and extrinsic pathways,
cf cf cf cf cf cf cf cf cf cf cf




cf conversion of prothrombin to thrombin, and fibrinogen to fibrin. Thrombocyte (platelet)
cf cf cf cf cf cf cf cf cf cf




cf formation is a process called thrombopoiesis, primarily taking place in the bone marrow,
cf cf cf cf cf cf cf cf cf cf cf cf




cf and is not a direct function of the coagulation cascade.

Which of the following increases the chance of clotting? Select all that apply.
cf cf cf cf cf cf cf cf cf cf cf cf cf cf




- Protein C deficiency
cf cf cf




Verified Explanation: cf cf cf




Protein C is a natural anticoagulant that degrades factors Va and VIIIa. Its deficiency results
cf cf cf cf cf cf cf cf cf cf cf cf cf cf




cf in a loss of inhibitory control of the coagulation cascade, thus increasing clotting risk. In
cf cf cf cf cf cf cf cf cf cf cf cf cf cf




cf contrast, vitamin K deficiency, vWF deficiency, and thrombocytopenia impair coagulation
cf cf cf cf cf cf cf cf cf




cf and increase bleeding risk.

The three stages of hemostasis include each of the following except:
cf cf cf cf cf cf cf cf cf cf cf cf

,- Vascular dilation
cf cf




Verified Explanation: cf cf cf




Hemostasis refers to the cessation of bleeding and consists of: (1) vascularcf cf cf cf cf cf cf cf cf cf cf




cf constriction, (2) formation of a platelet plug, and (3) blood coagulation. Vascular dilation is
cf cf cf cf cf cf cf cf cf cf cf cf cf




cf not a component of hemostasis and would, in fact, promote rather than prevent bleeding.

### Question 2 cf cf




Which of the following medications would decrease a person’s risk for clotting? Select
cf cf cf cf cf cf cf cf cf cf cf cf




cf all that apply.
cf cf cf cf




- Heparin
cf cf cf




- Warfarin
cf cf cf




- Lovenox (enoxaparin)
cf cf




Verified Explanation: cf cf cf cf




Heparin, warfarin, and Lovenox are anticoagulants that interfere with different aspects of
cf cf cf cf cf cf cf cf cf cf cf




cf coagulation. Heparin and Lovenox (a low-molecular-weight heparin) enhance
cf cf cf cf cf cf cf




cf antithrombin III activity, while warfarin inhibits vitamin K-dependent synthesis ofcf cf cf cf cf cf cf cf cf




cf clotting factors. Vitamin K is needed for clotting factor synthesis and could promote
cf cf cf cf cf cf cf cf cf cf cf cf




cf clotting if used in excess. cf cf cf cf

A deficiency in which of the following would lead to a hypercoagulable state? Select all
cf cf cf cf cf cf cf cf cf cf cf cf cf cf




cf that apply. cf cf cf




- Protein C
cf cf cf cf

, - Protein S
cf cf cf cf




- Antithrombin III
cf cf




Verified Explanation: cf cf cf




Protein C, Protein S, and Antithrombin III are endogenous anticoagulants. Deficiencies in
cf cf cf cf cf cf cf cf cf cf cf




cf these increase the risk for hypercoagulable states. Factors II, VII, IX, X, and prothrombin
cf cf cf cf cf cf cf cf cf cf cf cf cf




cf deficiencies lead to bleeding disorders, not clotting. cf cf cf cf cf cf

### Question 3 cf cf




Which of the following is NOT a hypercoagulable state? Select all that apply.
cf cf cf cf cf cf cf cf cf cf cf cf cf cf




- Hemophilia A
cf cf cf cf




- Hemophilia B
cf cf cf cf




- Thrombocytopenia
cf




Verified Explanation: cf cf cf




Hemophilia A and B are bleeding disorders caused by deficiencies of clotting factors VIII
cf cf cf cf cf cf cf cf cf cf cf cf cf




cf and IX, respectively. Thrombocytopenia is a condition of decreased platelet number and is
cf cf cf cf cf cf cf cf cf cf cf cf




cf associated with bleeding, not thrombosis (hypercoagulability).
