Disorders Of Hemoptysis

Question 1

Bleeding and clotting

Answer 1

Coag- process by which blood clots via coag cascade

Disorders—> bleeding or obstructive clotting

Question 2

Bleeding time

Answer 2

Plt eval- how long did it take the pt to clot

Question 3

Activated partial thrombophlebitis time (aPTT)

Answer 3

Evals the intrinsic pathway

Increase in heparin use, hemophilic, DIC, APS

Question 4

Prothrombin time (PT)

Answer 4

Evals the extrinsic pathway

Increase in warfarin use, liver dysfunction, Vit K def, DIC

Question 5

Fibrinogen

Answer 5

Protein precursor in fibrin

Decrease= greater bleeding risk

Question 6

D-dimer

Answer 6

Product of clot breakdown

Question 7

Coag factors

Answer 7

Factor VIII, vWF

Question 8

Hemostasis- mechanisms: primary

Answer 8

Plt adhesion
Activation
Aggregation creates hemostatic plug

Question 9

Hemostasis- mechanisms: secondary

Answer 9

Clotting factors are activated to form a fibrin complex- stabilizes platelet plug

Question 10

Hemostasis- mechanisms: liver

Answer 10

If it doesn’t work—> increase bleeding events
