Q1Which process reduces the number of pathogens on a surface to a safe level but does NOT kill all microorganisms?
Show answer
✓ Correct answer: Sanitation
Sanitation (cleaning) lowers microbial counts to safe public-health levels but does not eliminate all pathogens; disinfection destroys most pathogens, and sterilization destroys all microbial life including spores.
Q2An esthetician finishes a facial and places reusable metal implements in a covered container of EPA-registered disinfectant. What is the MINIMUM contact time required for most hospital-grade disinfectants to be effective?
Show answer
✓ Correct answer: 10 minutes
EPA-registered hospital-level disinfectants used in salons typically require a full 10-minute immersion contact time to achieve the stated kill claim, as specified on the product label.
Q3Which of the following is classified as an Other Potentially Infectious Material (OPIM) under OSHA's Bloodborne Pathogens Standard?
Show answer
✓ Correct answer: Cerebrospinal fluid
OSHA's Bloodborne Pathogens Standard lists cerebrospinal fluid as an OPIM because it can carry HIV and HBV, while sweat, tears, and intact skin are not considered infectious under the standard.
Q4A client accidentally nicks themselves during a treatment and blood is visible on the treatment table. Which approach does Standard Precautions require?
Show answer
✓ Correct answer: Treat ALL blood and body fluids as if infectious, regardless of the client's health status
Standard Precautions (formerly Universal Precautions) require treating every client's blood and body fluids as potentially infectious, regardless of known disease status, to prevent occupational exposure.
Q5Which of the following implements MUST be discarded after a single use on one client?
Show answer
✓ Correct answer: Wooden cuticle pusher
Porous or absorbent single-use implements such as wooden sticks cannot be adequately disinfected and must be discarded after each client; non-porous metal and glass tools can be disinfected and reused.
Q6Before immersing implements in an EPA-registered disinfectant, the esthetician must first:
Show answer
✓ Correct answer: Thoroughly clean implements to remove all visible debris
Disinfectants cannot penetrate organic matter such as blood, skin cells, or product residue; implements must be pre-cleaned to remove all visible debris before disinfection can be effective.
Q7An esthetician needs to look up the safe handling, storage, and first-aid procedures for a chemical peeling agent. Which document provides this information?
Show answer
✓ Correct answer: The Safety Data Sheet (SDS)
OSHA's Hazard Communication Standard requires that a Safety Data Sheet (SDS) accompany every hazardous chemical and detail health hazards, safe handling, PPE requirements, and emergency first-aid procedures.
Q8Which level of decontamination is required to render surgical instruments completely free of ALL microbial life, including bacterial spores?
Show answer
✓ Correct answer: Sterilization
Sterilization is the only process that destroys all forms of microbial life including highly resistant bacterial endospores; disinfection destroys most but not necessarily all spore-forming organisms.
Q9Which type of EPA-registered disinfectant is considered the most appropriate for general salon/spa use and is effective against HIV and HBV?
Show answer
✓ Correct answer: Hospital-level (intermediate-level) disinfectants effective against mycobacteria
The NIC and Milady curriculum specify that hospital-level (intermediate-level) EPA-registered disinfectants, which are effective against Mycobacterium tuberculosis, HIV, and HBV, are the standard required in professional esthetics settings.
Q10During a waxing service, the esthetician breaks skin on a client. What is the FIRST action the esthetician should take?
Show answer
✓ Correct answer: Stop the service, put on gloves, and follow exposure-control procedures
When blood or open skin is present, Standard Precautions require the esthetician to immediately don gloves and follow the facility's exposure-control plan before any further contact, to protect both client and practitioner.
