### Question 1
The coagulation cascade involves each of the following except:
- Make thrombocytes
,Verified Explanation:
The coagulation cascade is responsible for the conversion of soluble
plasma proteins into an insoluble fibrin clot. It includes activation of
intrinsic and extrinsic pathways, conversion of prothrombin to thrombin,
and fibrinogen to fibrin. Thrombocyte (platelet) formation is a process
called thrombopoiesis, primarily taking place in the bone marrow, and is
not a direct function of the coagulation cascade.
---
Which of the following increases the chance of clotting? Select all that
apply.
- Protein C deficiency
Verified Explanation:
Protein C is a natural anticoagulant that degrades factors Va and VIIIa. Its
deficiency results in a loss of inhibitory control of the coagulation
cascade, thus increasing clotting risk. In contrast, vitamin K deficiency,
vWF deficiency, and thrombocytopenia impair coagulation and increase
bleeding risk.
---
The three stages of hemostasis include each of the following except:
- Vascular dilation
, Verified Explanation:
Hemostasis refers to the cessation of bleeding and consists of: (1)
vascular constriction, (2) formation of a platelet plug, and (3) blood
coagulation. Vascular dilation is not a component of hemostasis and
would, in fact, promote rather than prevent bleeding.
---
### Question 2
Which of the following medications would decrease a person’s risk for
clotting? Select all that apply.
- Heparin
- Warfarin
- Lovenox (enoxaparin)
Verified Explanation:
Heparin, warfarin, and Lovenox are anticoagulants that interfere with
different aspects of coagulation. Heparin and Lovenox (a low-molecular-
weight heparin) enhance antithrombin III activity, while warfarin inhibits
vitamin K-dependent synthesis of clotting factors. Vitamin K is needed for
clotting factor synthesis and could promote clotting if used in excess.
