MULTIPLE CHOICE
1. The nurse recognizes which term to identify the second line of defense that leads to local
capillary dilation and leukocyte infiltration?
a. Normal flora
b. Inflammatory response
c. Immune response
d. Humoral immunity
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. Normal
flora is the body‘s first line of defense. The immune response is the body‘s attempt to protect
itself from foreign and harmful substances. Humoral immunity is a defense system that
involves white blood cells (B lymphocytes) that produce antibodies in response to antigens or
pathogens circulating in the lymph and blood.

2. The nurse knows that the antigen-antibody reaction is an example of what type of immunity?
N R I G B.C M
a. Humoral U S N T O
b. Cellular
c. Innate
d. Passive
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.

, DAWIT
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. Germ is a term used for microorganism. A
microorganism is bacteria, fungi, or protozoa.

4. The nurse is explaining to the patient why antibiotics are being administered. The answer
would be correct if the nurse stated antibiotics are effective against which microorganism?
a. Viruses
b. Fungi
c. Parasites
d. Bacteria
ANS: D
Antibiotics are effective against bacteria, and exact antibiotic sensitivity is tested so that
appropriate antibiotics are prescribed. Infections that are caused by fungi are treated with
antifungal medications. Certain antiviral medications are used to manage the symptoms of a
viral infection. These medications, if given during the early phases of illness, can decrease the
amount of time that the patient has viral symptoms. Treatment for parasitic infections varies
depending on type of parasite.

5. The nurse anticipates correctly that what medication category would be ordered to treat
athlete‘s foot?
a. Antiviral
b. Antibiotic
c. Antihelminth
d. Antifungal
ANS: D
The nurse would expect to treat athlete‘s foot with an antifungal because it is a fungal
infection. An antibiotic treats bacterial infections, antivirals treat viral infections, and
antihelminth treats parasitic worms.
