Infection Control and Management of Hazardous Materials for the Dental Team 7th Edition Test Bank

Chapter 01: Scope of Microbiology and Infection Control
Miller: Infection Control and Management of Hazardous Materials for the Dental
Team, 7th Edition

MULTIPLE CHOICE

1. Who is reported to have first observed microbes?

a.
b. Oliver Wendell Holmes
c. Lister
d. Leeuwenhoek
ANS: D
Pasteur, Oliver Wendell Holmes, and Lister made other important contributions to
microbiology. Leeuwenhoek first observed microbes and called them “animalcules.”

PTS: 1 DIF: Recall REF: p. 2 OBJ: 2
TOP: CDA, Infection Control, Does not apply

2. What year were microbes first observed?
a. 1667
b. 1880
c. 1956
d. 1975
ANS: A
Leeuwenhoek first observed microbes and called them “animalcules” in 1667, 1880, 1956,
and 1975 are all too recent.

PTS: 1 DIF: Recall REF: p. 2 OBJ: 2
TOP: CDA, Infection Control, Does not apply

3. Choose the microbial killing method referred to as pasteurization.
a. 121C for 20 minutes
b. 212F for 5 minutes
c. 63C for 30 minutes
d. 37C for 10 minutes

, Infection Control and Management of Hazardous Materials for the Dental Team 7th Edition Test Bank

ANS: C
121C for 20 minutes achieves sterilization. 212F for 5 minutes is the temperature of boiling
water. 63C for 30 minutes achieves pasteurization which kills harmful microbes in liquids
such as milk. 37C for 10 minutes is body temperature.

PTS: 1 DIF: Application REF: p. 2 OBJ: 2
TOP: CDA, Infection Control, III.A. Instrument/device processing

4. When was the “Golden Age of Microbiology”?
a. Mid to late 1600s
b. Mid to late 1700s
c. Mid to late 1800s
d. Mid to late 1900s
ANS: C
Mid to late 1600s and mid to late 1700s were too early. Mid to late 1800s was the time when
many new discoveries in microbiology were made. Mid to late 1900s was too late.

PTS: 1 DIF: Recall REF: p. 2 OBJ: 2
TOP: CDA, Infection Control, Does not apply

5. What microbes are used to make vinegar, vitamins, drain cleaners, enzymes, and other
products?
a. Fungi
b. Viruses
c. Protozoa
d. Bacteria
ANS: D
Fungi can make antibiotics but not these products. Viruses grow inside living cells and do not
make such products. Protozoa are not very efficient in making such products. Bacteria make
these and other products when they are grown in large vats.

PTS: 1 DIF: Recall REF: p. 3 OBJ: 3
TOP: CDA, Infection Control, Does not apply

6. Which microbes are used to make pickles out of cucumbers?
a. Bacteria or fungi
b. Fungi or viruses
c. Viruses or yeasts
d. Bacteria of viruses
ANS: A
Bacteria or fungi make certain extracellular products that change cucumbers into pickles.
Viruses do not produce products that affect cucumbers.

PTS: 1 DIF: Recall REF: p. 3 OBJ: 3
TOP: CDA, Infection Control, Does not apply

7. What microbe is used to make bread dough rise?
a. Bacteria
b. Yeasts
c. Viruses

, Infection Control and Management of Hazardous Materials for the Dental Team 7th Edition Test Bank

d. Protozoa
ANS: B
Bacteria do not produce enough carbon dioxide (CO2) to make the dough rise. Yeasts
metabolize carbohydrates to produce the gas bubbles of CO2 which causes the dough to rise.
Viruses only grow inside of living cells and do not have a regular metabolism. Protozoa do
not produce enough carbon dioxide (CO2) to make the dough rise.

PTS: 1 DIF: Recall REF: p. 3 OBJ: 3
TOP: CDA, Infection Control, Does not apply

COMPLETION

1. Louie Pasteur and John Tyndall first recognized the use of ___________ to destroy bacteria
and resistant spores.

ANS:
heat

Other physical procedures were found not to be as efficient as heat for killing microbes.

PTS: 1 DIF: Recall REF: p. 2 OBJ: 2
TOP: CDA, Infection Control, III.A. Instrument/device processing

2. In 1915 it was discovered that bacteria can be infected with viruses called
________________.

ANS:
bacteriophages

Animal viruses had been previously discovered, so they gave bacterial viruses a different
name – bacteriophages – phage means “to eat.”

PTS: 1 DIF: Recall REF: p. 3 OBJ: 1
TOP: CDA, Infection Control, Does not apply

3. Microbiology is the study of bacteria, molds, yeasts, protozoa, certain algae, viruses and
_________.

ANS:
archaea

Archaea are single cell microbes morphologically similar to bacteria, but their genes and
metabolic pathways are more closely related to eukaryotes. While they may be present in the
human body, there have been no clear examples of archaeal human pathogens.

TRUE/FALSE

1. The disease of smallpox was involved in the discovery of immunizations in the 1790s by
Edward Jenner.

ANS: T
Edward Jenner is credited with recognizing the concept of immunization when he realized in
the 1790s that milkmaids who caught cowpox, a mild disease, were protected from the more
serious disease of smallpox.

MULTIPLE CHOICE

1. Under what conditions do regular bacteria, excluding Rickettsia and Chlamydia, multiply?
a. In the absence of nutrients
b. Only when they are inside of living cells
c. When they are outside of living cells
d. Only when the temperature is below 7C

ANS: C
Nothing can grow in the absence of nutrients. Rickettsia and Chlamydia are the only bacteria
that can grow inside living cells. Regular bacteria do not need to be inside living cells to
grow. They can obtain their nutrients from the environment. Only the special bacteria called
psychrophiles can grow at these low temperatures.

PTS: 1 DIF: Application REF: p. 12 OBJ: 1
TOP: CDA, Infection Control, Does not apply

2. Select an environment in which viruses can multiply.
a. Only in the absence of nutrients
b. Only when they are inside of living cells
c. Only when they are outside of living cells
d. Only when the temperature is below 7C

ANS: B
Nothing can grow in the absence of nutrients. Viruses need the nutrients and metabolic
machinery of living cells to multiply. Viruses cannot obtain their nutrients from the
environment. Only the special bacteria called psychrophiles can grow at these low
temperatures.

PTS: 1 DIF: Application REF: p. 14 OBJ: 2
TOP: CDA, Infection Control, I.A. Standard precautions and the prevention of disease transmission

3. Which of the following microbes is a yeast?
a. Streptococcus mutans
b. Trichomonas vaginalis
c. Candida albicans
d. Staphylococcus aureus
