NURS 5433 Mock Test: Coagulation Cascade (ANCC AGANCP Testing Format)
Questions And Answers With Complete Solution
1. Which of the following correctly describes the intrinsic pathway in the coagulation
cascade?
A) Activated by external tissue damage, leading to the activation of Factor VII.
B) Initiated by the exposure of blood to foreign surfaces and involves Factors XII, XI, IX, and X.
C) Begins with the activation of Factor VII by Tissue Factor and culminates in the conversion of
Prothrombin to Thrombin.
D) Involves the activation of Factor X by the prothrombinase complex, leading to fibrinogen
cleavage.
2. What is the role of Factor VII in the extrinsic pathway?
A) It activates Factor IX in the intrinsic pathway.
B) It is activated by Tissue Factor to form the TF-VIIa complex, which then activates Factor X.
C) It activates Factor XI in the intrinsic pathway.
D) It binds with Factor X to form the prothrombinase complex.
3. In the coagulation cascade, which factor is essential for the formation of the tenase
complex?
A) Factor VIII
B) Factor V
C) Factor XII
D) Factor IX
4. Which of the following describes the function of thrombin in the coagulation cascade?
A) It activates Protein C to inhibit Factors Va and VIIIa.
B) It directly activates Factor VII to initiate the extrinsic pathway.
C) It converts fibrinogen to fibrin, forming the blood clot.
D) It forms the prothrombinase complex to convert Prothrombin to Thrombin.
5. Which of the following is a primary regulator of the coagulation cascade by inhibiting
activated Factor X and Factor IXa?
A) Protein S
B) Tissue Factor Pathway Inhibitor (TFPI)
C) Antithrombin III
D) Protein C
6. Which coagulation factor is responsible for converting fibrinogen into fibrin during the
coagulation cascade?
,A) Factor X
B) Factor XII
C) Thrombin
D) Factor XIII
7. What is the role of Factor XIII in the coagulation cascade?
A) Activates Factor X to Xa
B) Converts fibrinogen to fibrin
C) Stabilizes the fibrin mesh by crosslinking fibrin strands
D) Initiates the intrinsic pathway
8. Deficiency of which of the following factors is most commonly associated with
Hemophilia A?
A) Factor IX
B) Factor VIII
C) Factor VII
D) Factor X
9. The intrinsic pathway is activated when which of the following occurs?
A) Factor VII binds with Tissue Factor and activates Factor X.
B) Factor XII comes into contact with exposed collagen and activates Factor XI.
C) Prothrombin is converted to Thrombin.
D) Factor X is converted to Xa by the prothrombinase complex.
10. What is the final product of the coagulation cascade that stabilizes the blood clot?
A) Platelet plug
B) Fibrin meshwork
C) Factor XIIIa
D) Thrombin
Answer Key with Rationales:
1. B) Initiated by the exposure of blood to foreign surfaces and involves Factors XII, XI, IX,
and X.
Rationale: The intrinsic pathway is activated by contact with negatively charged surfaces, such
as collagen, which leads to the activation of Factor XII, followed by Factor XI, IX, and
ultimately Factor X.
2. B) It is activated by Tissue Factor to form the TF-VIIa complex, which then activates
Factor X.
, Rationale: Factor VII is activated by Tissue Factor (TF) and forms the TF-VIIa complex, which
is crucial for activating Factor X in the extrinsic pathway.
3. D) Factor IX
Rationale: Factor IX is essential for the formation of the tenase complex when it activates Factor
X in the intrinsic pathway, along with Factor VIIIa and calcium.
4. C) It converts fibrinogen to fibrin, forming the blood clot.
Rationale: Thrombin is a key enzyme that cleaves fibrinogen into fibrin, which then forms a
stable mesh to solidify the blood clot.
5. C) Antithrombin III
Rationale: Antithrombin III is a natural anticoagulant that inhibits Factor Xa and IXa, helping to
regulate the coagulation cascade.
6. C) Thrombin
Rationale: Thrombin cleaves fibrinogen into fibrin monomers, which polymerize to form the
fibrin mesh that stabilizes the clot.
7. C) Stabilizes the fibrin mesh by crosslinking fibrin strands
Rationale: Factor XIIIa, activated by thrombin, crosslinks fibrin strands to form a stable,
insoluble clot, crucial for long-term clot stability.
8. B) Factor VIII
Rationale: Hemophilia A is most commonly caused by a deficiency in Factor VIII, which is
essential for the activation of Factor X in the intrinsic pathway.
9. B) Factor XII comes into contact with exposed collagen and activates Factor XI.
Rationale: The intrinsic pathway is initiated when Factor XII is activated by contact with
exposed collagen, leading to a cascade of activations, including Factor XI and IX.
10. B) Fibrin meshwork
Rationale: The final product of the coagulation cascade is a stable fibrin mesh, which forms the
blood clot and prevents further blood loss.
