CPE Safety & Sanitation Standards 4 — Questions and Answers
Question 1: Sterilization differs from disinfection in that sterilization:
- Kills only bacteria and fungi
- Destroys all microbial life including spores (Correct answer)
- Requires chemical solutions rather than heat
- Is only required for non-critical items
Correct answer: Destroys all microbial life including spores
Sterilization destroys all forms of microbial life, including highly resistant bacterial endospores, whereas disinfection kills most but not all microorganisms.
Question 2: An electrologist notices the autoclave reached the correct temperature but the cycle timer failed to complete. What is the correct action?
- Use the items since temperature was reached
- Re-run a full sterilization cycle before using the items (Correct answer)
- Disinfect items with hospital-grade liquid as a substitute
- Quarantine items for 24 hours and then use them
Correct answer: Re-run a full sterilization cycle before using the items
Both correct temperature AND sufficient time are required to ensure sterilization; if the timer fails, the cycle must be rerun to guarantee efficacy.
Question 3: Which pathogen is most commonly associated with improper probe sterilization in electrolysis, posing a serious infection risk?
- Streptococcus pyogenes
- Staphylococcus aureus (Correct answer)
- Candida albicans
- Rhinovirus
Correct answer: Staphylococcus aureus
Staphylococcus aureus, including MRSA strains, is the most commonly reported pathogen in skin-penetrating cosmetology-related infections from improperly sterilized instruments.
Question 4: What does OSHA's Exposure Control Plan (ECP) require an employer to review and update?
- Every five years or when regulations change
- Annually and whenever new tasks or procedures create additional exposure risk (Correct answer)
- Only when a new employee is hired
- Only after an actual exposure incident occurs
Correct answer: Annually and whenever new tasks or procedures create additional exposure risk
OSHA mandates that the ECP be reviewed and updated at least annually and whenever new tasks or procedures could create additional exposure risks.
Question 5: Which disinfection method is NOT appropriate for electrology probes that will be reused?
- Steam autoclave at 250°F (121°C) for 30 minutes
- Dry heat oven at 320°F (160°C) for 1 hour
- Immersion in 70% isopropyl alcohol for 10 minutes (Correct answer)
- Chemical vapor sterilizer (chemiclave)
Correct answer: Immersion in 70% isopropyl alcohol for 10 minutes
Alcohol immersion achieves only intermediate-level disinfection, not sterilization, and is not an accepted method for reusable items that penetrate skin.
Question 6: Hand hygiene in electrology should be performed using which technique to be most effective?
- Quick rinse with water only between clients
- Antimicrobial soap scrub for at least 20 seconds covering all hand surfaces (Correct answer)
- Hand sanitizer applied only to palms
- Single-use wet wipes before gloving
Correct answer: Antimicrobial soap scrub for at least 20 seconds covering all hand surfaces
CDC guidelines call for washing all surfaces of both hands with soap for at least 20 seconds, which mechanically removes and kills transient pathogens effectively.
Question 7: If a client experiences a local skin infection following electrolysis, what is the electrologist's primary professional obligation?
- Prescribe an antibiotic cream from their supply
- Refer the client to a licensed healthcare provider for evaluation and treatment (Correct answer)
- Apply a stronger antiseptic at the next appointment
- Wait two weeks to see if the infection resolves naturally
Correct answer: Refer the client to a licensed healthcare provider for evaluation and treatment
Electrologists practice within their scope of practice, which does not include diagnosing or treating infections; referral to a healthcare provider is the appropriate action.
