Accepted Answer

A)   innate immunity
B)   adaptive immunity
C)   production of T & B cells
D)   the production of complements and interferons

Question 2

Identify the precautions and concerns that are required in order to do a tissue transplant.

Accepted Answer

Ideally the donor and recipient MHC antigens will be a perfect or near perfect match allowing the recipient to accept the donated tissue. Since it is very difficult to find a donor with the identical MHC match then immunosuppressive drugs can be administered to help decrease the potential for rejection.

Which of the following treatments can benefit from the use of monoclonal antibodies?

Accepted Answer

A)   Determining if a woman is pregnant or not.
B)   Diagnosis of respiratory tract infections in young children.
C)   Detection and treatment of various forms of breast cancer.
D)   All of these treatments can benefit from the use of monoclonal antibodies.

Question 5

What specific part of the antibody determines the class of the antibody?

Accepted Answer

A)   variable region of the light chain and heavy chain
B)   antigen binding sites
C)   constant region
D)   All of these are correct.
E)   None of these are correct.

Question 6

Which is NOT part of a description of an antibody molecule?

Accepted Answer

A)   contains two light chains and two heavy chains
B)   contains an antigen-binding site on each arm
C)   contains a constant and a variable region on each chain
D)   forms an X-shaped protein molecule

Question 7

Accepted Answer

A)   X-linked agammaglobulinemia (XL
A)  
B)   AIDS
C)   Asthma
D)   None of these disorders can be treated by gene therapy during the embryological stage.

Question 10

Which of these statements is NOT true about complement?

Accepted Answer

A)   Complement is a complex of plasma proteins that are activated in the presence of pathogens.
B)   Complement is required for formation of antigen-antibody complexes.
C)   Complement forms holes in bacterial membranes and allows fluid and salts to enter a bacterial cell.
D)   Complement attracts phagocytes to the bacterial cell and increases its likelihood of being engulfed.

Question 11

Complement and interferon are specific kinds of antibodies.

Accepted Answer

A) True 
 B)False

Question 12

Antigens are

Accepted Answer

A)   proteins produced by virus-infected cells that stimulate an immune response.
B)   molecules produced by white blood cells that stimulate other white blood cells, namely T cells.
C)   chemicals that enhance all lymphatic organs.
D)   proteins produced by plasma cells that stimulate the clotting of blood.

Question 13

Innate immunity is a defense system that becomes fully functional after it has undergone a period of exposure to various pathogens.

Accepted Answer

A) True 
 B)False

Question 14

The presence of antibodies in a newborn baby is most often due to

Accepted Answer

A)   exposure of the baby to antigens after birth.
B)   antibodies that crossed the placenta from the mother's blood.
C)   immunity developed after birth.
D)   natural immunity developed in the baby before birth.
E)   antibodies are inherited from the father.

Question 15

If a person is bitten by a highly venomous snake and receives a dose of venom sufficient to kill several people, that person does not have the time to build up his immunity over the next week to neutralize the venom. However, hospitals carry "antivenin" made from injecting horses with small-to-larger dosages of snake venom, and then harvesting the antibodies from the horse plasma. This is an example of

Accepted Answer

A)   passive immunity.
B)   active immunity.
C)   developing an inflammatory response to increase the IgG production.
D)   receiving high levels of complement.
