NURS 3550 - Week 6 Questions with Detailed Verified
Answers
Hemostasis Ans: ✓ ✓ ✓ The process that prevents and stops bleeding, involving the formation of a
platelet plug.
Platelet Plug Formation Ans: ✓ ✓ ✓ Occurs when blood vessel damage exposes collagen,
activating platelets to change shape, release ADP and TXA2, and aggregate to stop bleeding.
Coagulation: Extrinsic Pathway Ans: ✓ ✓ ✓ Activated by tissue factor outside the blood, leading to
the activation of factor VII, which activates factor X and catalyzes prothrombin into thrombin.
Thrombin Ans: ✓ ✓ ✓ An enzyme that catalyzes fibrinogen into fibrin, activates factor V into Va,
and converts factor VIII into its active form VIIIa.
Coagulation: Intrinsic Pathway Ans: ✓ ✓ ✓ Activated by factors within the blood, starting with
factor XII exposed to collagen, leading to the activation of factor X.
Thrombosis Ans: ✓ ✓ ✓ The formation of a blood clot within a blood vessel.
Anticoagulants Ans: ✓ ✓ ✓ Drugs that disrupt the coagulation cascade and suppress fibrin
production, primarily used for venous thrombosis.
Antiplatelets Ans: ✓ ✓ ✓ Medications that prevent platelet aggregation, primarily used for arterial
thrombosis.
Thrombolytics Ans: ✓ ✓ ✓ Drugs that break up fibrin and dissolve thrombi.
Unfractionated Heparin Ans: ✓ ✓ ✓ A long polysaccharide chain drug that binds to antithrombin
to inactivate thrombin and factor Xa, preventing venous thrombosis.
Low Molecular Weight Heparins (LMWHs) Ans: ✓ ✓ ✓ Heparins with smaller molecular
composition that preferentially inactivate factor Xa and do not require lab monitoring.
