,Chapter 1: A Brief History of Microbiology (5th Ed., Bauman).
1. The Early Years of Microbiology (Questions 1–4)
1. Which scientist is credited with first observing
microorganisms using a primitive microscope?
A. Louis Pasteur
B. Robert Koch
C. Antonie van Leeuwenhoek
D. Ignaz Semmelweis
Rationale: Leeuwenhoek made the first detailed observations
of bacteria and protozoa using handcrafted lenses. Pasteur and
Koch came later; Semmelweis worked on hand hygiene.
2. The concept of spontaneous generation was widely accepted
until experiments by:
A. Robert Hooke
B. Edward Jenner
C. Francesco Redi
D. Ferdinand Cohn
Rationale: Redi’s meat-and-maggot experiments challenged
spontaneous generation. Hooke described cells; Jenner
developed vaccination; Cohn classified bacteria.
3. Early contributions to microbiology by Robert Hooke
included:
,A. Describing the cell as the fundamental unit of life
B. Observing mold structures in a cork slice
C. Establishing pasteurization
D. Defining bacterial taxonomy
Rationale: Hooke coined “cell” after viewing cork.
Pasteurization was Pasteur’s work; bacterial taxonomy
developed later.
4. Which statement best reflects the nursing importance of
early microscopy?
A. It led to immediate antibiotic therapy.
B. It allowed visualization of pathogens, reinforcing infection
control.
C. It prevented all hospital-acquired infections.
D. It made vaccines obsolete.
Rationale: Microscopy enabled nurses to appreciate unseen
pathogens and practice hand hygiene and disinfection.
Antibiotics and vaccines came later; infections remained a risk.
2. Microbial Classification: Bacteria, Archaea, Fungi, Protozoa,
Algae (Questions 5–8)
5. Which group of organisms lacks a nucleus and has
peptidoglycan in its cell wall?
A. Bacteria
B. Archaea
,C. Fungi
D. Protozoa
Rationale: Bacteria are prokaryotes with peptidoglycan.
Archaea lack peptidoglycan. Fungi and protozoa are eukaryotic.
6. Methanogens belong to which domain?
A. Bacteria
B. Archaea
C. Fungi
D. Protozoa
Rationale: Methanogens are archaea that produce methane
under anaerobic conditions. Bacteria do not produce methane.
7. Yeasts and molds are classified as:
A. Algae
B. Protozoa
C. Fungi
D. Bacteria
Rationale: Yeasts and molds are fungal organisms; algae
perform photosynthesis; protozoa are motile eukaryotes.
8. Which microbial group is most likely to perform
photosynthesis in aquatic nursing facility water sources?
A. Protozoa
B. Algae
C. Archaea
D. Fungi
,Rationale: Algae are eukaryotic photosynthesizers. Protozoa
are heterotrophic; archaea and fungi do not photosynthesize.
3. Spontaneous Generation Experiments: Redi, Needham,
Spallanzani, Pasteur (Questions 9–12)
9. In Needham’s experiment, boiled broth was left open, and
microorganisms appeared because:
A. His boiling destroyed all organisms
B. His boiling time was insufficient to kill spores
C. He sealed the flasks too tightly
D. He used sterile instruments
Rationale: Needham’s short boil left heat-resistant spores,
allowing microbial growth. Spallanzani later improved on
boiling time and sealing.
10. Spallanzani’s experiment improved on Needham’s by:
A. Showing microbes generate spontaneously
B. Using unboiled broth
C. Boiling longer and sealing flasks
D. Observing fermentation
Rationale: Spallanzani boiled longer and sealed flasks to
prevent air entry, stopping microbial growth and challenging
spontaneous generation.
11. Pasteur’s swan-neck flask experiment demonstrated:
,A. Microbes arise only in boiled broth
B. Fermentation produces disease
C. Airborne microbes can be trapped without broth
contamination
D. Broth spoils only in sealed vessels
Rationale: Pasteur showed that microbes from air settle in the
neck bend, not reaching the broth, disproving spontaneous
generation.
12. A nursing implication of Pasteur’s work on airborne
microbes is:
A. All bacteria are airborne
B. Handwashing is unnecessary
C. Sterile gowns prevent epidemics
D. Proper air filtration reduces infection spread
Rationale: Understanding airborne transmission led to using
filters and ventilation to reduce hospital-acquired infections.
Gowns and handwashing address contact transmission.
4. The Scientific Method (Questions 13–15)
13. Which step of the scientific method involves forming a
testable statement?
A. Observation
B. Experimentation
, C. Hypothesis
D. Conclusion
Rationale: A hypothesis is a predictive, testable statement.
Observations lead to hypotheses; experiments test them.
14. A nurse researcher suspects hand sanitizer reduces surgical
site infections. Testing this is an example of:
A. Theory development
B. Hypothesis testing
C. Data collection without hypothesis
D. Publication
Rationale: Testing the effect of hand sanitizer on infection rates
directly tests a hypothesis.
15. If data do not support a hypothesis, the scientific method
dictates you should:
A. Modify or reject the hypothesis
B. Hide the data
C. Declare it a theory
D. Repeat experiments or revise the hypothesis
Rationale: Negative results lead to revision and further testing.
Hiding data violates scientific ethics.
5. Fermentation: Pasteur and Buchner (Questions 16–18)
16. Pasteur showed that fermentation is caused by:
