Flashcards in Midterm Deck (11):
1

Primary Hemostasis is characterized as (3) events

1. Vascular constriction 2. Platelet Aggregation 3. Soft aggregate plug

2

During primary hemostasis, adhesion occurs when BLANKK attaches to the sub endothelium.

Von willebrand factor vWf allows glycoproteins to adhere to the sub endothelium

3

Primary hemostasis has a BLANKKK time interval, where as Secondary hemostasis has BLANKK time interval.

Primary=Short lived 20 seconds after injury
Secondary=Long lived

4

Secondary hemostasis is responsible for (2) events

stabilizing the soft clot and maintaining vasoconstriction

5

Vasoconstriction is maintained through the platelet secretion of .... (3)

Serotonin, thromboxane, and prostaglandin

6

As fibrin sets up into a clot, BLANKKK is deposited in to the forming clot until it is activated into plasmin.

Plasminogen

7

Plasmin is a

fibrinolytic enzyme that degrades fibrin to remove the clot.

8

Bleeding Time BT is a BLANKKK test

Platelet Function test

9

Bleeding time is (dependent or independent) on the coagulation

independent, platelet plug will form regardless of fibrin formation

10

How will the bleeding time change during thrombocytopenia?

it will be prolonged due to a decreased platelet number

11

What are the two methods of performing a BT test?

Duke method-Stab method to ear lobe
AND
Ivy Bleeding TIme-incision to the forearm
