BMS FREE BMS Bachelor of Mortuary Science Pathology and Microbiology Questions and Answers 2 — Questions and Answers
Question 1: Which type of necrosis is most commonly associated with Mycobacterium tuberculosis infection?
- Caseous necrosis (Correct answer)
- Coagulative necrosis
- Liquefactive necrosis
- Fat necrosis
Correct answer: Caseous necrosis
Caseous necrosis produces a soft, white, cheese-like appearance characteristic of tuberculosis granulomas.
Question 2: What is the primary virulence factor that allows Staphylococcus aureus to resist phagocytosis?
- Protein A (Correct answer)
- Coagulase
- Hyaluronidase
- Hemolysin
Correct answer: Protein A
Protein A binds the Fc region of IgG antibodies, preventing opsonization and phagocytic killing.
Question 3: In the context of embalming, which pathogen is classified as a CDC Biosafety Level 3 organism?
- Mycobacterium tuberculosis (Correct answer)
- Escherichia coli
- Staphylococcus epidermidis
- Candida albicans
Correct answer: Mycobacterium tuberculosis
M. tuberculosis requires BSL-3 precautions due to its airborne transmission and serious infection risk during embalming procedures.
Question 4: Which immunoglobulin class is the first antibody produced during a primary immune response?
- IgM (Correct answer)
- IgG
- IgA
- IgE
Correct answer: IgM
IgM is the earliest antibody produced and is effective at agglutination due to its pentameric structure.
Question 5: What type of inflammation is characterized by the formation of granulomas with multinucleated giant cells?
- Chronic granulomatous inflammation (Correct answer)
- Acute serous inflammation
- Fibrinous inflammation
- Suppurative inflammation
Correct answer: Chronic granulomatous inflammation
Chronic granulomatous inflammation features organized collections of macrophages that fuse into multinucleated giant cells around persistent irritants.
Question 6: Which microorganism is an obligate anaerobe commonly found in gangrene and is a major concern during tissue preparation?
- Clostridium perfringens (Correct answer)
- Pseudomonas aeruginosa
- Bacillus subtilis
- Streptococcus pyogenes
Correct answer: Clostridium perfringens
Clostridium perfringens produces gas and tissue-destroying toxins that cause gas gangrene, a significant concern in mortuary science.
