Quiz #3 Genetics, Immune and Abnormal Response Disorders

Question 1

To have active immunity, a person must have been exposed to an antigen or

receive a gamma globulin injection

receive the vaccine for that disease

receive antibodies from their mother

receive antibodies from their identical twin

Answer 1

receive the vaccine for that disease

Pg211

Question 2

Incompatible blood transfusions cause a type II hypersensitivity response. What is the result of this response?

autoantibody production with erythrocyte destruction

lymphocyte destruction due to an immunodeficiency

erythrocyte production

erythrocyte hemolysis causing hypoxia

Answer 2

erythrocyte hemolysis causing hypoxia

Pg 215

Question 3

Lymphocytes that do not require sensitization to a specific antigen that respond by directly attacking antigens are
Correct answer:

natural killer cells

beta cells

plasma cells

CD-4 T cells

Answer 3

natural killer cells

Question 4

Which symptoms would cause a nurse to suspect that an HIV positive patient may have developed AIDS?

abdominal pain with clay-colored stools

intense itching with a vesicular body rash

inflamed joints with a butterfly facial rash

recurrent opportunistic infections

Answer 4

recurrent opportunistic infections

pg. 231. Immune suppression makes the patient more susceptible to opportunistic infections.

Question 5

Which abnormality is an example of a type 4/delayed hypersensitivity reaction?

allergic rhinitis

transplant rejection

ABO blood incompatibility

rheumatoid arthritis

Answer 5

transplant rejection

Pg216

Question 6

Misaligned chromosomes can cause changes in the development of the fetus. Which disorder is the most common chromosomal abnormality?

cystic fibrosis

Duchennes muscular dystrophy

Huntington’s disease

Down syndrome

Answer 6

Down syndrome

Question 7

Immune reactions against MHC (HLA) self antigen cause the formation of antibodies against the bodies own tissue known as

immunoglobulin (IgG)

CD 4 cells

T-cells

autoantibodies

Answer 7

autoantibodies

Question 8

The primary role of CD4 T helper cells is

control release of cytokines

influence all immune system cells

kill cancer cells

production of antibodies

Answer 8

influence all immune system cells

Question 9

Jane took the flu vaccine this year but was exposed to her grandson who was diagnosed with flu. Five days later she developed the flu. Which of the following statements explains why Jane developed the flu? (Select 3 that apply)

Janes immune system failed to produce antibodies to the virus

Vaccine did not cover the specific virus

Having the flu vaccine caused her to have the flu

Jane has no prior exposure to the specific virus

Answer 9

Janes immune system failed to produce antibodies to the virus

Vaccine did not cover the specific virus

Jane has no prior exposure to the specific virus

Jane has not had prior exposure to the particular strain of virus and therefore does not have immunity. Flu vaccine does not cover all possible strains making it less than 100% effective against all possible flu viruses.

Question 10

In order for an autosomal recessive trait to be manifested, the trait must be

heterozyous or recessive

homozygous

multifactorial and recessive

x-linked or dominant

Answer 10

homozygous
