Immunologic Disorder (CWP Down) Flashcards

Damage occurs from immune complexes that form with either class IgM
or _____ antibodies because they have complement binding sites.

IgG

People with type A blood ______ anti-A antibodies in their plasma.

Lack

A RhoGAM shot during pregnancy and right after the birth of each
Rh-positive child helps prevent the formation of anti-Rh antibodies in
an Rh negative mother so she will not develop ________ cells.

Memory

Blood pressure _____ when histamine cause vasodilatation and
increased capillary permeability.

Drops

An example of Type II (Cytotoxic) hypersensitivity is _______ _______;
Hapten molecules of a drug (like aspirin) accumulate on the surface
of erythrocytes and stimulate an immune response that lyses them.

Hemolytic Anemia

Histamine release initiates ____________.

Inflammation

Hemolytic disease of the newborn can occur when an Rh ______ mother
is carrying her second or later Rh positive fetus.

Negative

Type I hypersensitivity reactions are referred to as __________
because they occur quickly (20-30 minutes average)

Immediate

Hypersensitivity refers to an ___________ reaction (over reaction)
that ends up damaging the host.

Allergic

Allergic contact dermatitis occurs when haptens bind to skin proteins;
Urushiol oils (_____) of poison ivy, cosmetics, deodorants, metals
in jewelry, and latex may all be responsible.

Catechols

An example of Type II (cytotoxic) hypersensitivity is a __________
transfusion reaction if the wrong ABO blood type is given to a patient;
Too many RBC's lyse too quickly, too much hemoglobin is released and
the liver can't handle it all at once; increase bilirubin and
biliverdin levels are toxic to tissues, resulting in jaundice, nausea,
chills, fever, shock, and death.

Hemolytic

A RhoGAM shot during pregnancy and right after the birth of each Rh
____ child helps prevent the formation of anti-Rh antibodies in an Rh
negative mother.

Positive

For a successful packed red cell transfusion, the ABO antigens on the
erythrocyte of the _______ must be complementary to the naturally
occurring plasma antibodies of the recipient.

Donor
