Question 1

What is the primary function of fibrinogen in the coagulation process?

Accepted Answer

To form fibrin, which creates a mesh to stabilize blood clots

Answer

To transport oxygen in the blood

Answer

To activate platelets in the coagulation cascade

Answer

To break down clots after they have formed

Question 2

Which condition is characterized by low levels of fibrinogen?

Accepted Answer

DIC (Disseminated Intravascular Coagulation)

Answer

Hemophilia

Answer

Answer

400-600 mg/dL

Answer

50-100 mg/dL

Answer

100-200 mg/dL

Question 4

What laboratory test is commonly used to measure fibrinogen levels?

Accepted Answer

Fibrinogen assay

Answer

Activated partial thromboplastin time (aPTT)

Answer

Prothrombin time (PT)

Answer

Platelet count

Question 5

What effect does an increase in fibrinogen levels typically have on coagulation?

Accepted Answer

It enhances clot formation and may lead to thromboembolic events

Answer

It has no effect on the coagulation process

Answer

It causes rapid breakdown of clots

Answer

It decreases clotting ability

Question 6

Answer

Excessive bleeding

Answer

Aspirin use

Answer

Hemophilia

Question 7

What is the role of fibrinogen in the process of wound healing?

Accepted Answer

It helps form a stable clot to control bleeding

Answer

It reduces inflammation at the wound site

Answer

It transports nutrients to the wound site

Answer

It enhances the immune response

Question 8

Which laboratory test would show a prolonged prothrombin time (PT) if fibrinogen levels are low?

Accepted Answer

Fibrinogen assay

Answer

Basic metabolic panel (BMP)

Question 9

What condition can result from significantly high fibrinogen levels?

Accepted Answer
