Chapter 06: Innate Immunity: Inflammation and Wound HealingMULTIPLE CHOICE
1. A public health nurse is teaching the community about health promotion. Which
information should the nurse include for innate immunity? Innate immunity is gained:
a. following an illness.
b. at birth.
c. via injection of specific antibodies.
d. in adulthood.
ANS: B
Innate immunity is present at birth. It is not dependent on illness or injection.
REF: p. 134
2. Which statement indicates teaching was successful regarding collectins? Collectins
are produced by the:
a. kidneys.
b. bowel.
c. lungs.
d. integument.
ANS: C
Collectins are produced by the lungs. Collectins are not associated with the kidneys, bowel, or
integumentary system.
REF: p. 135
3. A 20-year-old male received a knife wound to the arm during an altercation. Which of
the following types of immunity was compromised?
a. Innate immunity
b. Inflammatory response
c. Adaptive immunity
d. Specific immunity
ANS: A
The epithelial cells of the skin are a part of innate immunity. The inflammatory response is
not a type of immunity. Adaptive immunity is represented by the normal flora of the bowel.
Specific immunity is a type of adaptive immunity and is not associated with a break in skin
integrity.
REF: pp. 134-135
4. Biochemical secretions that trap and kill microorganisms include:
a. hormones.
b. neurotransmitters.
c. earwax.
d. gastric acid.
, ANS: C
Epithelial cells secrete several substances that protect against infection, including earwax.
Hormones do not contain biochemical secretions that trap and kill microorganisms.
Neurotransmitters carry important messages, and gastric acid helps break down food into its
component parts, but neither contains biochemical secretions.
REF: p. 135
5. A 25-year-old female presents to her primary care provider reporting vaginal discharge of a
white, viscous, and foul-smelling substance. She reports that she has been taking antibiotics
for the past 6 months. Which finding will the nurse most likely see on the microorganism
report?
a. Clostridium difficile overgrowth
b. Decreased Lactobacillus
c. Streptococcus overgrowth
d. Decreased Candida albicans
ANS: B
Diminished colonization with Lactobacillus that occurs as a result of prolonged antibiotic
treatment increases the risk for vaginal infections, such as vaginosis. Clostridium difficile and
Candida albicans occur in the colon, not the vagina. Streptococcus overgrowth will occur in
the mouth.
REF: p. 136
6. When an aide asks the nurse about the purpose of the inflammatory process, how should
the nurse respond? N R I G B.C M
a. To provide specific responsUes tSowaNrd aTntigensO.
b. To lyse cell membranes of microorganisms.
c. To prevent infection of the injured tissue.
d. To create immunity against subsequent tissue injury.
ANS: C
One purpose of the inflammatory process is to prevent infection and further damage by
contaminating microorganisms. Specific response toward antigens is a part of the complement
system that assists in the inflammatory response, but not its purpose. Lysis of cell membranes
is part of the process of phagocytosis, which removes foreign material. Immunity cannot be
achieved against future tissue injury.
REF: p. 137
7. A child fell off a swing and scraped his right knee. The injured area becomes painful.
What else will the nurse observe upon assessment?
a. Vasoconstriction at injured site
b. Decreased RBC concentration at injured site
c. Pale skin at injured site
d. Edema at injured site
ANS: D
Increased vascular permeability and leakage of fluid out of the vessel cause edema at the
site of injury. Vasodilation occurs, bringing increased RBCs to the site and causing redness.
