1
Serum is plasma that has been altered in the laboratory to remove
fibrinogen or some other elements that is unnecessary in the sample.
true - plasma differs from serum in that serum is plasma that been
allowed to clot in the laboratory in order to remove fibrinogen and other
clotting factors that may interfere with some diagnostic tests.
2
Erythropoietin induces the selective proliferation of proerythroblasts.
true - in the confines of bone marrow erythoid progenitor cells
proliferate and differentiate into large, nucleated proerythroblasts that
are committed into producing cells of the erythroid series (figure 25-12)
3
In the clotting process, collagen provides a particularly strong stimulus
to activate platelets.
true - other stimuli of platelet activation include epinephrine, thrombin,
and collagen. Thrombin and collagen are particularly strong stimuli.
4
Once activated, the clotting cascade is immediately controlled by
counteracting anticoagulants.
true - the major regulatory factors that control hemostasis reside where
the greatest probability of clotting would occur: on the endothelial cell
surface (figure 25-17). the primary anticoagulant mechanisms include
thrombin inhibitors (e.g., antithrombin III), tissue factor inhibitors (e.g.,
NURS 6050
, NURS 6050
tissue factor pathway inhibitor), and mechanisms for degrading
activated clotting factors (e.g., protein C).
5
The surface of the endothelium produces plasma protease inhibitors to
resist clot formation.
true - thrombomodulin is a membrane thrombin-binding protein matter
and is converted to activated protein C (Figure 25-17) on the surface of
endothelial cells. Protein C in the circulation binds to thrombomodulin.
Activated protein C inhibits the adhesion of neutrophils to the
endothelium.
6
the neruologic symptoms in vitamin B12 deficiency anemia are not
reversed even with appropriate treatment.
true - neurologic manifestations result from nerve demyelination that
may produce neuronal death. these complications pose a serious threat
because they are not reversible, even with appropriate treatment.
7
DIC is a paradoxical condition in which clotting and hemorrhage occur
within the vascular system simultaneously.
true - most symptoms are the result of either hemorrhage or thrombosis.
8
In DIC, a large amount of microvascular and macrovascular occlusion
may occur that is not clinically obvious.
true
