MULTIPLE CHOICE

1. The second line of defense that leads to local capillary dilation and leukocyte infiltration is known as:

ANS:  B

The second line of defense is the inflammatory response. Inflammation is a local response to cellular injury or infection that includes capillary dilation and leukocyte infiltration. The immune response is the body’s attempt to protect itself from foreign and harmful substances. Humoral immunity is an adaptive immunity and normal flora is a group of non–disease-causing microorganisms (e.g., bacteria, fungi, protozoa) that live in or on the body.

2. The antigen-antibody reaction is an example of what type of immunity?

ANS:  A

Humoral immunity is a defense system that involves antibodies and white blood cells that are produced to fight antigens. Cellular immunity involves defense by white blood cells against any microorganisms that the body does not recognize as its own. The innate (nonspecific) immune system provides immediate defense against foreign antigens. Passive immunity occurs when a person receives an antibody produced in another body.

3. The nurse administers an immunization consisting of antibodies against hepatitis B. The nurse knows this is a form of what type of immunity?

ANS:  C

The body did not have to work to develop the immunity; therefore, it is passive, and the patient was artificially exposed. It is not innate because it was provided. It was not naturally acquired because it was given in the vaccine.

4. A disease-causing organism is known as:

ANS:  A

Infectious agents include any disease-causing agent and are called pathogens. They include bacteria, fungi, viruses, and parasites. Normal flora is a group of non–disease-causing microorganisms that live in or on the body. A microorganism is bacteria, fungi, or protozoa.
