MULTIPLE CHOICE

 

BASIC CONCEPTS

 

1. What is the role of the T lymphocyte (T cell) in the development of long-lasting antibody-mediated immunity?

a.	Enhancing the sensitized B lymphocyte’s production of antibodies on second and subsequent exposure to the same antigen
b.	Preventing general immune responses from becoming excessive and leading to autoimmunity
c.	Distinguishing sensitized B lymphocytes from unsensitized B lymphocytes
d.	Assisting unsensitized B lymphocyte to recognize new antigens

 

 

ANS:  D

The T lymphocyte has many roles in cell-mediated immunity. Its major role in antibody-mediated immunity is helping unsensitized B lymphocytes to recognize foreign invaders (antigens) and learn to make antibodies against them. T lymphocytes do not prevent autoimmunity and do not promote the memory function of increased antibody production on reexposure to the same antigen. T lymphocytes do not distinguish between sensitized and unsensitized B lymphocytes.

2. With which disorder or organism is a killed vaccine used to trigger immunity?

a.	Tetanus
b.	Influenza
c.	Hepatitis B
d.	Human papilloma virus

 

 

ANS:  B

The vaccines for tetanus, hepatitis B, and human papilloma virus are all toxoids. Only the vaccine for influenza has been inactivated and is considered a “killed” vaccine.

3. Which statement regarding artificially acquired active immunity is true?

a.	It requires “boosting” on a regular schedule.
b.	It is present in only children and not in adults.
c.	It can be used for vaccinations but not for immunizations.
d.	It has the shortest duration of effectiveness of any type of immunity.

 

 

ANS:  A

Artificially acquired active immunity is long-lasting but requires boosting on a specific schedule to remain effective. This type of immunity can develop in adults as well as in children.

4. What is definition of a toxoid that can be used for vaccination?

a.	A vaccine containing antibodies that were produced by other animals in response to the administration of human white blood cells.
b.	A vaccine that contains a modified toxin that an organism produces or a small part of the actual organism.
c.	A vaccine designed to be toxic to or inhibit the excessive functioning of the immune system.
d.	A vaccine that contains artificially created antibodies that will generate passive immunity.

 

 

ANS:  B

A toxoid is a vaccine, not an antibody, that contains either a modified toxin an organism produces or a small part of the actual organism. It does not contain any type of antibodies and does not inhibit immune functioning.

5. Which vaccination is routinely administered to infants at ages 2 months, 4 months, and 6 months?

a.	HyperTET
b.	RhoGAM
c.	TdaP
d.	DTaP

 

 

ANS:  D

HyperTET is only given to a person who is heavily exposed to the tetanus organism and does not have adequate immunity to the organism. RhoGAM is only given to an Rh-negative woman who has given birth to an Rh-positive newborn. TdaP is a modified vaccination of tetanus, diphtheria, and pertussis given to older children and adults who have already received the DTaP series. DTaP is the vaccination given in infancy and early childhood to develop immunity to diphtheria, tetanus, and pertussis.
