Correct Answer is B

Explanation

A. A systemic infection

A systemic infection would involve symptoms throughout the body (e.g., fever, malaise, elevated heart rate).

B. A localized infection

The signs-redness, warmth, swelling, drainage-are localized to the site of injury, indicating a local infection.

C. A normal response to the injury

While some redness or swelling is expected, greenish drainage is a sign of infection, not normal healing.

D. An allergic reaction

Allergic reactions typically involve itching, hives, or rash-not purulent drainage or warmth.

A. The failure of the body to function normally B. A diseased section of the body C. The invasion of the body by a pathogen and the subsequent symptoms in response to the invasion D. The invasion of the body by a disease

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.
