Final: Module 13

Question 1

the intravenous administration of whole blood, its components, or blood-based products for therapeutic purposes

Answer 1

Blood therapy

Question 2

Blood donated from someone else

Answer 2

allogenic blood

Question 3

substances that elicit specific immune responses when they come in contact with foreign substances

Answer 3

antigens

Question 4

essential element in immune function, based on antigens present on leukocytes and platelets and is important to determine prior to repeated platelet transfusions

Answer 4

Human Leukocyte Antigens (HLA)

Question 5

collection, filtration, and reinfusion of patient’s own blood

Answer 5

autologous transfusion

Question 6

process where blood is withdrawn from teh pateitn immediately prior to surgery and replaced with an IV infusion of crystalloid/colloid solution to maintain volume for adequate circulation. Collected blood is infused after bleeding is controlled

Answer 6

hemodilution

Question 7

contains RBC, WBC, platelets, and plasma

Answer 7

whole blood

Question 8

living tissue able to transprot electrolytes, proteins, hormones, vitamins, antibodies, ehat and oxygen to tissues of the bdoy

Answer 8

whole blood

Question 9

hormone produced by kidnies when they sense inadequate RBC. Causes bone marrow to make RBC

Answer 9

Erythropoietin

Question 10

Important in hemostasis, cessation of blood flow, coagulation blood clotting, and are natural source of growth factors

Answer 10

Platelets

Question 11

single donor’s platelets are harvested and the RBC are returned to the donor yielding 6-10 units of transferable platelets

Answer 11

Apharesis

Question 12

straw colored protion of blood- acts as carrier for blood cells, nutrients, enzymes, and hormones. Contains antibodies to fight infection

Answer 12

Plasma

Question 13

fraction of the plasma that separates out when FFP is slowly thawed in the refrigerator. Contains several clotting factors found in plasma but is a smaller amount of liquid. Decreases microvascular bleeding during special procedures

Answer 13

Cryoprecipitate

Question 14

the replacement of the patient’s total blood volume within 24 hours

Answer 14

Massive transfusion

Question 15

systemic response to the administration of blood product that is incompatible iwth that of the recipient, contains allergens to which the recipient is sensitive or allergic or is contaminated with pathogens

Answer 15

Hemolytic reaciton

Question 16

syndrome of acute respiratory distress, often associated with fever, noncardiogenic pulmonary edema, and hypotension. Assocaited with HLA antibodies

Answer 16

Transfusion realted acute lung injury

Question 17

donor lymphocytes are identified as foreign but immune system not capable in destroying them (immunocompromised)- patient’s lymphocytes are destroyed

Answer 17

Graft vs Host Disease

Question 18

patient has developed antibodies against human leukocyte antigen (HLA) or platelet antigens- makes cross matching difficult and often results in febrile allergic reaction.

Answer 18

Alloimmunization

Question 19

stimulates the sympathetic nervous system to relieve resipratory distress and combat vasodilation in anaphylaxis

Answer 19

epinephrine

Question 20

diminishes some aspects of allergic response by blocking histamine receptors

Answer 20

antihistamine

Question 21

administered when bacterial contamination/sepsis is suspected

Answer 21

antibiotics

Question 22

administered to relieve fever and discomfort in acute hemolytic reactions, febrile non-hemolytic reactions, graft vs host disease, and bacterial sepsis

Answer 22

Antipyretics/analgesics

Question 23

may be administered in cases of circulatory overload to reduce intravascular volume and decrease vascular tone

Answer 23

diuretics/morphine

Question 24

stabilize cell membranes and decrease histamine release. Administered incase of severe allergic reactions

Answer 24

corticosteriods

Question 25

rapid administration of this may help counteract some fo the symptoms of anaphylactic shock

Answer 25

IV fluids
