CH Safety & Infection Control 3 — Questions and Answers
Question 1: What is the primary purpose of a biological indicator (spore test) in the context of equipment sterilization?
- To verify that the equipment surface is visually clean
- To confirm that sterilization conditions were sufficient to kill the most resistant microorganisms (Correct answer)
- To measure the chemical concentration of the sterilant
- To check the mechanical function of the sterilizer
Correct answer: To confirm that sterilization conditions were sufficient to kill the most resistant microorganisms
Biological indicators use highly resistant spores (e.g., Geobacillus stearothermophilus) to confirm that the sterilization process achieved lethal conditions.
Question 2: Under OSHA's Bloodborne Pathogens Standard, which of the following must be provided to employees at no cost?
- Personal health insurance
- Hepatitis B vaccination series (Correct answer)
- Annual influenza vaccination
- COVID-19 booster shots
Correct answer: Hepatitis B vaccination series
OSHA 29 CFR 1910.1030 requires employers to offer the Hepatitis B vaccine series free of charge to all employees with occupational exposure.
Question 3: During a session, the speculum becomes dislodged and fecal material splashes. What is the correct immediate response?
- Continue the session and clean up afterward
- Apply pressure and continue while wearing extra gloves
- Stop the session, address the client's safety, remove contaminated PPE, perform hand hygiene, and decontaminate the area (Correct answer)
- Rinse the area with water only and resume
Correct answer: Stop the session, address the client's safety, remove contaminated PPE, perform hand hygiene, and decontaminate the area
Any accidental release of fecal material requires immediate session stoppage, proper PPE removal, hand hygiene, and full surface decontamination to prevent pathogen spread.
Question 4: What does the term 'chain of infection' refer to in infection control?
- The hierarchy of pathogens ranked by lethality
- The sequential steps required for an infection to spread, including infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host (Correct answer)
- The series of disinfection steps required after a session
- The regulatory chain of command for reporting infections
Correct answer: The sequential steps required for an infection to spread, including infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host
Breaking any one of the six links in the chain of infection can prevent disease transmission, which is the basis of all infection control measures.
Question 5: Which of the following client conditions is an absolute contraindication that also raises significant infection control concerns during colonic hydrotherapy?
- Mild constipation
- Active rectal bleeding or hemorrhaging (Correct answer)
- Mild bloating
- History of appendectomy
Correct answer: Active rectal bleeding or hemorrhaging
Active rectal bleeding creates a direct portal of exit for bloodborne pathogens, making the procedure both medically contraindicated and an extreme infection risk.
Question 6: How should a colonic hydrotherapist dispose of liquid waste containing fecal matter from equipment cleaning?
- In a regular trash receptacle with a sealed bag
- Down a sanitary sewer drain connected to a municipal treatment system (Correct answer)
- In a hazardous waste container for incineration only
- Buried on facility grounds per local ordinance
Correct answer: Down a sanitary sewer drain connected to a municipal treatment system
Fecal liquid waste is considered sanitary waste and must be disposed of via a sanitary sewer system connected to a sewage treatment facility.
Question 7: An exposure incident involving potential contact with blood or OPIM must be reported to the employer within what timeframe per OSHA guidelines?
- Within 72 hours
- Immediately or as soon as feasible (Correct answer)
- Within 30 days
- At the next scheduled employee review
Correct answer: Immediately or as soon as feasible
OSHA requires immediate reporting of exposure incidents because post-exposure prophylaxis (PEP) is most effective when started promptly.
