BMS FREE BMS Funeral Service Microbiology and Pathology Questions and Answers 2 — Questions and Answers
Question 1: Which type of bacteria is most commonly associated with gas gangrene in deceased remains?
- Clostridium perfringens (Correct answer)
- Staphylococcus aureus
- Escherichia coli
- Bacillus subtilis
Correct answer: Clostridium perfringens
Clostridium perfringens produces gas in tissues through anaerobic fermentation, causing the characteristic bloating seen in gas gangrene.
Question 2: What is the primary purpose of a disinfectant used on embalming instruments between cases?
- To destroy pathogenic microorganisms on surfaces (Correct answer)
- To sterilize instruments completely
- To remove visible organic matter
- To neutralize formaldehyde residue
Correct answer: To destroy pathogenic microorganisms on surfaces
Disinfectants are applied to destroy pathogenic microorganisms on instrument surfaces, reducing the risk of cross-contamination.
Question 3: Which bloodborne pathogen poses the greatest occupational risk to embalmers due to its environmental stability?
- Hepatitis B virus (Correct answer)
- HIV
- Hepatitis A virus
- Influenza virus
Correct answer: Hepatitis B virus
Hepatitis B virus can survive on dry surfaces for up to seven days, making it the most persistent bloodborne threat in the preparation room.
Question 4: During autolysis, which cellular organelle releases enzymes that begin breaking down the cell from within?
- Lysosomes (Correct answer)
- Mitochondria
- Golgi apparatus
- Endoplasmic reticulum
Correct answer: Lysosomes
Lysosomes contain hydrolytic enzymes that, upon cell death, rupture and digest cellular components in the process of autolysis.
Question 5: What condition results when anaerobic bacteria in the intestines migrate through tissue walls after death?
- Translocation (Correct answer)
- Livor mortis
- Rigor mortis
- Desiccation
Correct answer: Translocation
Translocation is the postmortem migration of intestinal bacteria through weakened tissue barriers into surrounding organs and tissues.
Question 6: Which personal protective equipment is considered MOST critical when handling remains with suspected Mycobacterium tuberculosis?
- N95 respirator (Correct answer)
- Latex gloves
- Face shield
- Disposable gown
Correct answer: N95 respirator
An N95 respirator is essential because M. tuberculosis is transmitted via airborne droplets that standard surgical masks cannot adequately filter.
