Question 1

Process of blood clotting to arrest bleeding and re-establishment of blood flow during the healing process

Answer 1

Hemostasis

Question 2

What are the parameters involved in Hemostasis?

Answer 2

• Vascular
• Platelets
• Fibrin clot formations - coagulation cascade
• Control (inhibitory systems)
• Fibrinolysis

Question 3

What is the concept of primary hemostasis vs secondary hemostasis ?

Answer 3

primary hemostasis is the process of platelet aggregation (white thrombus) while secondary hemostasis involves the formation of fibrin strands that incorporate red cells into that mesh (red thrombus)

These process help with stopping a vascular bleed.

Question 4

Decreased number of platelets

Answer 4

Thrombocytopenia

Question 5

increased number of platelets

Answer 5

Thrombocytosis

Question 6

blood in the urine

Answer 6

Hematuria

Question 7

bleeding into the joints

Answer 7

Hemathralgia

Question 8

bleeding into the brain

Answer 8

Intracranial hemorrhage

Question 9

bruise

(a collection of small blood pools beneath the skin)

Answer 9

Purpura

Question 10

bruise

(a small bruise caused by blood leaking from broken blood vessels into the tissue of the skin or mucous membranes)

Answer 10

Ecchymoses

Question 11

bruise

(a pool of mostly clotted blood that forms in a an organ, tissue, or body space)

Answer 11

Hematoma

Question 12

fancy term for a nose bleed

Answer 12

Epistaxis

Question 13

heavy menstrual bleeding

Answer 13

Menorrhagia

Question 14

a clot

Answer 14

Thrombus

Question 15

a clot

(abnormal)

Answer 15

Thrombosis

Question 16

Abnormal clotting happens in the deep veins

(usually in the legs)

Answer 16

Deep Vein Thrombosis (DVT)

Question 17

heart attack

(a clot lodging in the heart can cause this)

Answer 17

Myocardial infarct (MI)

Question 18

another word for stroke

(a blood clot lodging in the brain can cause this)

Answer 18

Cerebral Vascular Accident (CVA)

Question 19

substance that is prepared from human plasma that can be transfused and it has certain constituents in it, but not all of the coagulation factors.

Answer 19

Cryoprecipitate

Question 20

this is given to individuals (when they are bleeding) to help replenish their coagulation factors to help them stop bleeding

Answer 20

Fresh frozen plasma

Question 21

What happens when there is damage or injury to a blood vessel?

Answer 21

When there is vessel that is damage, blood is pouring out of the blood vessel and epithelial cells are disrupted.

First thing that happens is primary hemostasis where the platelets come together (aggregate). Thus you have the damage blood vessel interaction with the platelets and they forma platelet plug to stop the hole.

Next is secondary hemostats where fibrin develops to strengthen the plates by stabilized and close the gap so blood can’t get through that damage vessel anymore.
