Immunity

An infant receives a diphtheria, tetnus, and acellular pertussis (DTaP) immunization at a well-baby clinic. The parent returns home and calls the clinic to report that the infant has developed swelling and redness at the site of injection. Which intervention should the nurse suggest to the parent?

• Monitor the infant for a fever
• Bring the infant back to the clinic
• Apply a hot pack to the injection site?
• Apply a cold pack to the injection site

The first vaccines for humans against viruses used killed or attenuated viruses to generate immunity without causing serious illness.

• True
• False

Special proteins produced by the body to attack foreign invaders.

• antibodies
• antigen

Unlike active immunity, passive immunity causes

• long term resistance to disease
• short and long term resistance to disease
• no resistance to disease
• short term resistance to disease

Two types of lymphocytes (white blood cells) include

• A cells and B cells
• T cells and B cells
• C cells and Z cells
• eukaryotes and prokaryotes

An immune response is triggered by a(an)

• antibiotic.
• antibody.
• antigen.
• histamine.

When a person receives a vaccine, his or her body

• receives antibodies against a specific pathogen.
• creates plasma cells that can produce antibodies against the specific pathogen.
• creates antigens to fight the specific pathogen.
• immediately begins fighting the infection caused by the pathogens.

If a person has memory B cells against a certain pathogen, the person is

• likely to develop that disease.
• much less likely to develop the disease a second time.
• able to spread the disease to others through physical contact.
• probably still sick with the disease.

Substances that causes the body to produce antibodies are:

• antigens
• pandemic
• pathogen
• epidemic

A person who develops antibodies against the flu vaccine is generating

• cell-mediated immunity.
• active immunity
• passive immunity
