QUESTIONS 1–150
Question 1
A nail technician is preparing to perform a manicure after completing services
for a client with visible blood contamination on a reusable metal implement.
Which procedure is most appropriate?
A. Wipe the implement with alcohol and reuse it
B. Rinse the implement and place it directly in the disinfectant
C. Remove gross contamination using appropriate precautions, then clean and
properly disinfect the implement
D. Spray the implement with a surface sanitizer and allow it to air-dry
🔴 Correct Answer: C. Remove gross contamination using appropriate
precautions, then clean and properly disinfect the implement
🔵 Explanation: Blood and other visible debris must be removed before
effective disinfection can occur. Appropriate personal protective precautions
should be used, followed by cleaning and immersion in an appropriate
disinfectant according to its label instructions.
Question 2
A technician accidentally nicks a client's skin during cuticle work and observes
active bleeding. What should the technician do FIRST?
A. Continue the service while avoiding the injured area
B. Immediately stop the service and follow the salon's exposure-control
procedure
C. Apply nail dehydrator to sterilize the wound
D. Cover the injury with acrylic enhancement material
🔴 Correct Answer: B. Immediately stop the service and follow the salon's
exposure-control procedure
🔵 Explanation: An accidental cut creates a potential blood exposure. The
service should stop immediately, appropriate protective measures should be
used, and the affected area and contaminated materials should be managed
according to established infection-control procedures.
Question 3
,3 NAIL TECHNICIAN
A disinfectant is labeled for use only after instruments have been thoroughly
cleaned. A technician places visibly contaminated implements directly into the
disinfectant. Why is this procedure inadequate?
A. Disinfectants work only on disposable implements
B. Organic debris can interfere with the disinfectant's effectiveness
C. Disinfectants must always be diluted with alcohol
D. Metal instruments cannot be disinfected by immersion
🔴 Correct Answer: B. Organic debris can interfere with the disinfectant's
effectiveness
🔵 Explanation: Cleaning removes debris that can shield microorganisms and
interfere with chemical disinfection. The manufacturer’s cleaning, dilution,
contact-time, and storage directions must be followed.
Question 4
A salon uses a disinfectant requiring a specific concentration and contact time.
The technician notices that the solution is being changed every morning
regardless of contamination level. Which principle is most important?
A. The solution must always remain unchanged for seven days
B. The manufacturer's instructions and applicable regulations determine proper
use and replacement
C. Daily replacement automatically makes incorrect dilution acceptable
D. Contact time is irrelevant if the solution appears clear
🔴 Correct Answer: B. The manufacturer's instructions and applicable
regulations determine proper use and replacement
🔵 Explanation: Disinfectant effectiveness depends on correct preparation,
concentration, contact time, and replacement practices. Appearance alone
cannot establish efficacy, and applicable regulatory requirements must also be
followed.
Question 5
Which item presents the strongest reason for using a single-use disposable
abrasive file?
A. It is difficult to sharpen
B. Its porous surface can be difficult or impossible to adequately disinfect
, 4 NAIL TECHNICIAN
C. It cannot contact natural nails
D. It always contains hazardous chemicals
🔴 Correct Answer: B. Its porous surface can be difficult or impossible to
adequately disinfect
🔵 Explanation: Porous or absorbent materials may retain microorganisms
and cannot necessarily be rendered safe through routine immersion
disinfection. Single-use items should be discarded after use when required by
their construction or applicable rules.
Question 6
A technician places cleaned implements into a disinfectant container but
removes them after only half the labeled exposure time. What is the principal
concern?
A. The instruments will become too clean
B. Required antimicrobial contact may not have occurred
C. The instruments will lose their metallic properties immediately
D. The disinfectant becomes permanently inactive
🔴 Correct Answer: B. Required antimicrobial contact may not have
occurred
🔵 Explanation: Disinfectants require the labeled contact time to achieve their
intended efficacy. Premature removal may result in inadequate disinfection
even when the correct chemical and concentration are used.
Question 7
Which practice best demonstrates effective cross-contamination prevention
during a manicure?
A. Returning unused product from a client's service container to the original
container
B. Using the same towel for several clients if it appears clean
C. Preventing contaminated implements from contacting clean supplies
D. Placing used implements beside clean implements for convenience
🔴 Correct Answer: C. Preventing contaminated implements from
contacting clean supplies
