Q

reverse

stoppage of bleeding resulting from breaking in a blood vessel

A

Hemostasis

19
Q

reverse

vascular spasm

platelet plug formation

coagulation (blood clotting)

A

phases of hemostasis

20
Q

reverse

occurs immediatly if a vessel is cut or broken

spasm narrows the vessel decreasing blood loss

A

Vascular spasms

21
Q

reverse

collagen fibers are exposed by break in vessel

platelets become “sticky” and cling to fibers

anchored platelets release chemicals to attract more platelets

platelets pile up to for a plug

A

platelet plug formation

22
Q

reverse

most effective homeostatic mechanism

final step conversion of fibrogen into insoluable fibrin threads

Thrombin: enzyme that converts fibrinogen into fibrin

fibrin forms meshwork that traps RBC

blood usually clots in 3-6 min

clot remains as endothelium regenerates

clot is broken down after tissue repair

A

Coagulation

blood clotting

23
Q

reverse

loss of 15-30% causes weakness

loss of over 30% causes shock which can be fatal

A

Blood loss

24
Q

reverse

transfusions are the only way to replace blood quickly

transfused blood must be of the same blood group

A

Blood Transfusion

25
Q

reverse

antigens: proteins found on surface of RBC
antibodies: clumping of RBC due to interaction of antigens and antibodies

A

Blood group genetic proteins

26
Q

reverse

grouped based on presence or absence of 2 major protein antigens on the RBC membrane

4 ypes: A, B, AB and O

2-8 mos after birth the body may synthesize certain antibodies

Antibodies A or B

found within plasma

A

Blood groups

27
Q

reverse

Antigens: both A and B

Antibodies: neither A or B

A

Type AB blood

28
Q

reverse

Antigens: A is present

Antibodies: B is present

A

Type A blood

29
Q

reverse

Antigens: B is present

Antibodies: A is present

A

Type B blood

30
Q

reverse

Antigens: lack A and B

Antibodies: A and B are present

A

Type O blood

31
Q

reverse

can receive A, B, AB or O blood

Universal recipient

A

AB transfusion

32
Q

reverse

can receive A and O blood

A

A transfusion

33
Q

reverse

can receive B and O blood

A

B transfusion

34
Q

reverse

can receive O blood

universal donor

A

O transfusion

35
Q

reverse

presence or absence of antigen D

Rh negative: RBC lasck Rh antigen

Rh positive: RBC has antigen

person with rh neg blood does not make anti Rh unless exposed to Rh positive blood

A

RH blood groups

36
Q

reverse

person with negative blood receives transfusion of positive blood

initial is not problme but anti body cells begin synthesizing anti-Rh antibodies

person is now sensitized to Rh-positive blood

next exposure wo Rh positive blood will cause recipients blood to agglutinate with donors RBC

A

Rh Sensitization

37
Q

reverse

when mother is Rh- and father is Rh+

Erythroblastosis Fetalis

A

Rh pregnance dangers

38
Q

reverse

Rh- mother carrying Rh+ baby

first child no problem

after mother is sensitized to Rh+ and will produce anti Rh antibodies

2nd pregnancy will attack Rh+ blood of fetus

A

Erythroblastosis Fetalis

39
Q

reverse

shot to prevent buildup of anti Rh+ antibodies in mothers blood

A

RhoGAM shot

40
Q

reverse

blood type is determinede by finding which antigens are present on RBC membrane

blood is typed by using antibodies that will cause blood with certain antigens to clump

ABO and Rh typing are done in similar manner

A

Blood Typing

41
Q

reverse

testing for agglutination of donors RBC by the recipients serum and vice versa

A

Cross matching

42
Q

reverse

expose sample to anti A antibodies and anti B antibodies

look for clumping (agglutination)]

if clumping present the antigen is present on the RBC

A

Agglutination testing

43
Q

reverse

always best to give person their own blood

A

Blood Transfusions

44
Q

reverse

agglutination of donor RBC because recipients plasma contains antibodies against the antigens on donor RBC

A

Transfusion reaction
