MNT Infection Control & Sanitation 2 — Questions and Answers
Question 1: Which term describes a chemical that kills or inhibits the growth of microorganisms on living tissue?
- Disinfectant
- Antiseptic (Correct answer)
- Sterilant
- Sanitizer
Correct answer: Antiseptic
Antiseptics are formulated for use on living skin or tissue, while disinfectants are for inanimate surfaces.
Question 2: A nail technician notices a client has a green discoloration under a nail enhancement. What is the most likely cause?
- Fungal infection
- Pseudomonas bacterial infection (Correct answer)
- Viral infection
- Allergic reaction to monomer
Correct answer: Pseudomonas bacterial infection
Green discoloration under nail enhancements is a classic sign of Pseudomonas aeruginosa bacterial infection.
Question 3: What is the minimum contact time typically required for an EPA-registered disinfectant to be effective on implements?
- 30 seconds
- 1 minute
- 10 minutes
- The full time listed on the product label (Correct answer)
Correct answer: The full time listed on the product label
The EPA requires that disinfectants be used according to label directions, which specify the required contact time for efficacy.
Question 4: Which hepatitis virus is most commonly associated with occupational exposure risk through needlesticks or blood contact in a salon setting?
- Hepatitis A
- Hepatitis B (Correct answer)
- Hepatitis C
- Hepatitis D
Correct answer: Hepatitis B
Hepatitis B is highly transmissible through bloodborne contact and is the primary occupational concern in environments where skin breaks can occur.
Question 5: When using a disinfectant solution, implements should be completely submerged to ensure:
- Faster chemical reaction
- All surfaces are exposed to the disinfectant (Correct answer)
- The solution changes color to indicate activation
- The implement is sterilized
Correct answer: All surfaces are exposed to the disinfectant
Complete submersion ensures that all surfaces, including crevices, come into full contact with the disinfectant for proper decontamination.
Question 6: A client arrives with an active cold sore (herpes labialis). What is the safest course of action?
- Proceed with service using gloves
- Apply antiseptic to the area and continue
- Reschedule the appointment until the sore has healed (Correct answer)
- Cover the sore with a bandage and proceed
Correct answer: Reschedule the appointment until the sore has healed
Active herpes lesions are highly contagious; service should be rescheduled to prevent cross-contamination of tools and spread to others.
Question 7: What does OSHA's Bloodborne Pathogens Standard primarily require nail salons to maintain?
- A log of all chemical products used
- An Exposure Control Plan (Correct answer)
- A weekly disinfection schedule
- A client health history database
Correct answer: An Exposure Control Plan
OSHA's Bloodborne Pathogens Standard mandates that employers with occupational exposure risk maintain a written Exposure Control Plan.
