◉ "It will decrease the risk of obtaining white blood cells from the
donor that could make it harder for your transplanted kidney to
function.". Answer: A 37-year-old man with polycystic kidney
disease is on the kidney transplant list. He is to receive 2 units of
leukocyte-poor packed red blood cells to treat a low hemoglobin. He
asks the nurse why he needs this type of blood. What is the nurse's
best response?
"It causes fewer blood reactions for pre-transplant patients."
"It is less likely to causes hemolysis, or destruction of the blood cells,
after transfusion."
"All pre-transplant patients receive leukocyte-poor blood because it
is absorbed better by the body."
"It will decrease the risk of obtaining white blood cells from the
donor that could make it harder for your transplanted kidney to
function."
,◉ false. Answer: True or False: Inflammation means that an
infection is always present.
True
False
◉ hypersensitivities/ allergies. Answer: Increased/excessive
response to presence of antigen exposure
Degree of reaction ranges from:
Uncomfortable (itchy, watery eyes; sneezing)
Life threatening (allergy asthma, anaphylaxis, bronchoconstriction,
circulatory collapse)
◉ Type I: Rapid Hypersensitivity Reactions (immediate). Answer:
Also called atopic allergy
Most common type
Some reactions occur only in areas of antigen exposure
Caused by increased production of immunoglobulin E (IgE) antibody
class
Allergens contracted by:
Inhalation (pollens, spores, animal dander, dust, grass, ragweed)
Ingestion (foods, food additives, drugs)
Injection (bee venom, drugs, biologic substances)
,Contraction (latex, pollens, foods, environmental proteins)
Anaphylaxis (medical emergency)
Blood vessel dilation
Decreased cardiac output
Bronchoconstriction
◉ allergic rhinitis. Answer: Also known as hay fever
Triggered by reaction to airborne allergens:
Plant pollens
Molds
Dust
Animal dander
Wool
Food
Air pollutants
◉ anaphylaxis. Answer: Life-threatening type I hypersensitivity
reaction
Rapid, systemic
Can be fatal
◉ 1. Answer: latex allergy is a type ____ allergy.
, ◉ type 2: cytotoxic reactions (myasthenia gravis). Answer: Body
makes special autoantibodies directed against self cells that have
some form of foreign protein attached to them
Clinical examples:
Hemolytic anemias
Immune thrombocytopenic purpura
Hemolytic transfusion reactions
Goodpasture's syndrome
Drug-induced hemolytic anemia
◉ type 3: immune complex reactions (rheumatoid arthritis).
Answer: Excess antigens cause immune complexes to form in blood
Circulating complexes lodge in small blood vessels
Usual sites: Kidneys, skin, joints
Deposited complexes trigger inflammation, resulting in tissue or
vessel damage
Examples:
Rheumatoid arthritis
Systemic lupus erythematosus
◉ type 4: delayed hypersensitivity (poison ivy). Answer: Reactive
cell is T-lymphocyte (T-cell)
