A person has a severe pharyngitis (sore throat). He is most likely to develop:

A.

Enlarged, painful cervical lymph nodes

B.

Enlarged thymus gland

C.

Enlarged inguinal lymph nodes

D.

Cervical lymph node cancer

Answer and Explanation

The Correct Answer is A

A. Enlarged, painful cervical lymph nodes:

The cervical lymph nodes drain the area of the throat. Infection leads to inflammation and enlargement of these nodes.

B. Enlarged thymus gland:

The thymus is primarily active in children and does not respond to infections like lymph nodes do.

C. Enlarged inguinal lymph nodes:

Inguinal lymph nodes drain the lower extremities and genital area, not the throat.

D. Cervical lymph node cancer:

Cancer is not a typical complication of pharyngitis. Lymph node enlargement here is due to immune response, not malignancy.

Correct Answer is C

Explanation

A. The failure of the body to function normally

This is too general and applies to any illness, not specifically infection.

B. A diseased section of the body

This is vague and doesn’t identify causative factors like pathogens.

C. The invasion of the body by a pathogen and the subsequent symptoms in response to the invasion

This accurately defines infection as a host response to pathogen invasion.

D. The invasion of the body by a disease

Diseases don’t invade; pathogens do. This option is not scientifically accurate.

Correct Answer is B

Explanation

A. Naturally acquired passive immunity

Passive immunity occurs when antibodies are transferred (e.g., from mother to baby); it does not involve the person’s immune system actively responding.

B. Naturally acquired active immunity

This occurs when a person is exposed to a pathogen, like the measles virus, and their body mounts an immune response, producing long-lasting immunity.

C. Artificially acquired active immunity

This is obtained through vaccination, not from infection.

D. Artificially acquired passive immunity

This refers to receiving antibodies (e.g., through injection of immune globulin), not through natural infection.
