Finals Exam Review (Qns & Ans)
2025
1. Which pathogen is most commonly associated with post-
surgical infections?
- A) Staphylococcus aureus
- B) Escherichia coli
- C) Clostridium difficile
- D) Streptococcus pyogenes
Correct ANS: A) Staphylococcus aureus
©2025
, Rationale : Staphylococcus aureus is a leading cause of post-
surgical infections due to its ability to enter through incision sites
and its frequent presence on skin.
2. Which of the following is a confirmatory test for
Mycobacterium tuberculosis?
- A) Gram stain
- B) Acid-fast bacilli (AFB) smear
- C) Catalase test
- D) Coagulase test
Correct ANS: B) Acid-fast bacilli (AFB) smear
Rationale : The AFB smear specifically targets the
characteristic lipid-rich cell wall of Mycobacterium species,
especially tuberculosis.
3. Which of the following antibiotic classifications inhibits
protein synthesis?
- A) Beta-lactams
- B) Macrolides
- C) Fluoroquinolones
- D) Sulfonamides
Correct ANS: B) Macrolides
©2025
, Rationale : Macrolides inhibit bacterial protein synthesis by
binding to the 50S ribosomal subunit, thereby blocking peptide
bond formation.
4. During which phase of the bacterial growth cycle does the
population double in number?
- A) Lag phase
- B) Log phase
- C) Stationary phase
- D) Death phase
Correct ANS: B) Log phase
Rationale : The log phase is characterized by rapid cell
division and exponential growth of bacteria, leading to a doubling
in population.
Fill-in-the-Blank Questions
5. The three main shapes of prokaryotic bacteria are
__________, __________, and __________.
Correct ANS: coccus, bacillus, spirillum
Rationale : These shapes define the basic morphology of
bacteria and are critical for identification and classification.
