24
Q

It is the collection
of information on the complications of transfusion, analysis
of these data, and subsequent data-driven improvements in
transfusion practices.

A

Hemovigilance

25
Q

It is the development of non-ABO anti -

bodies following RBC transfusion, pregnancy, or transplantation.

A

Alloimmunization

26
Q

some individuals may be more susceptible than others to developing RBC alloantibodies. These persons, called

A

responders

27
Q

is defined as
the combination of signs and symptoms associated with
hemolysis, biochemical evidence of hemolysis, and serologic
evidence of RBC incompatibility occurring during or within 24 hours after transfusion.

A

AHTR Acute hemolytic transfusion reaction

28
Q

AHTR is due to

A 
RBC transfusion (incompatible)
- but they can occur with incompatible plasma-containing products
29
Q

What is the most common symptoms in AHTRs

A

FEVER

30
Q 
What type of acute transfusion reaction, that upon testing will present a positive DAT?
A. allergic severe
B. acute immune hemolytic
C. febrile non-hemolytic
D. transfusion-associated sepsis
A

Q

is a rare event associated with acute respiratory distress but a leading cause of mortality due to adverse reactions to transfusion.

32
Q

T/F “Possible
TRALI” is designated when the above criteria are present
but another cause of ALI is also identified, w

A

TRUE

33
Q

T/F “delayed

TRALI” refers to when criteria for TRALI are present but the onset is 6–72 hours after transfusion.2

35
Q

is an adverse reaction characterized by acute respiratory distress from pulmonary edema caused by increased
intravascular volume due to excessive transfused fluid and/or
too rapid of an infusion rate and the inability of the patient
to accommodate the volume of transfused products due to
impaired pulmonary, cardiac, or renal function.

True

43

B. anaphylactoid reaction
C. both
D. none
A

B. anaphylactoid reaction

47
Q

What is the clinical severity found with ATRs

A

mild skin reaction

48
Q

What is the most common manifestation of ATRs

mucocutaneous reactions including;
urticaria
pruritus
generalized rash

49
Q

What is the most commonly reported symptoms of Adverse Reaction to infusion of Plasma- Derived Products

A

Headache

50
Q

is a rare but devastating event with a very high mortality rate
compared to other transfusion reactions as well as with
GVHD occurring in marrow/hematopoietic and solid organ
transplantation.

Transfusion-Associated Graft-Versus-Host Disease

TA-GVHD

51
Q

the most common symptoms of TA-GVHD

A 
rash
fever
increased liver enzymes 
pancytopenia 
diarrhea
52
Q

is a rare transfusion reaction
in which there is a severe and sudden drop in the platelet
count, usually occurring 5 to 10 days after transfusion due
to alloimmunization to platelet-specific antibodies from
prior transfusion or pregnancy.
