Which of the Following is Correct Regarding Inflammation

Question

Which of the following is correct regarding inflammation?
A) The cardinal signs include rash.
B) Some of the phagocytes are stimulated to secrete antibodies specific for the invading pathogen.
C) There is increased blood volume.
D) Differentiation of B cells into plasma cells occurs at the site of infection.
E) AIDS patients have little or no inflammatory responses when they are infected.

Accepted Answer

Inflammation is characterized by increased blood flow and blood volume to the affected area, which leads to redness, warmth, and swelling.

Answer: E
 AIDS patients, whose immune systems are severely compromised, may have little or no inflammatory response when they are infected with pathogens. This can be dangerous because inflammation is an important way that the body responds to infection and helps to eliminate pathogens.

Answers A, B, and D are incorrect.
 None of these choices are accurate statements about inflammation. The cardinal signs of inflammation include redness, warmth, swelling, pain and loss of function (not rash). Phagocytes, such as neutrophils and macrophages, can engulf and destroy pathogens but they do not secrete antibodies. B cells differentiate into plasma cells in lymphoid organs, not at the site of infection.
