A barber in Virginia uses a straight razor on a client with a known history of
hepatitis B. Which post-service disinfection protocol for the razor is compliant
with current Virginia Board regulations and CDC guidance?
A. Wipe the razor with a 70% isopropyl alcohol wipe and store it in a
closed drawer.
B. Immerse the disassembled razor in an EPA-registered hospital-grade
disinfectant with a tuberculocidal claim for the manufacturer's
recommended contact time.
C. Spray the razor with a quaternary ammonium disinfectant and air-dry
it on a clean towel.
D. Rinse the razor under hot water, then place it in a UV sterilizer for 10
minutes.
Correct Answer: B - Immerse the disassembled razor in an
EPA-registered hospital-grade disinfectant with a tuberculocidal
claim for the manufacturer's recommended contact time.
RATIONALE
Bloodborne pathogens such as hepatitis B require an EPA-registered
hospital-grade disinfectant with a tuberculocidal claim, used for the
full contact time; alcohol wipes, quaternary ammonium sprays, and
UV units do not meet this standard for blood-contaminated
implements. Disassembly ensures all surfaces contact the disinfectant.
Question 2
During a consultation, a client requests a relaxer service but presents with scalp
abrasions and a history of allergic reaction to hair dye. Which action best
reflects Virginia barber scope of practice and client safety?
A. Proceed with a mild relaxer after applying a protective base to the
scalp.
B. Perform a patch test 24 hours before the service and proceed if

, negative.
C. Decline the chemical service, document the contraindications, and
refer the client to a dermatologist or physician.
D. Substitute a no-lye relaxer and proceed with the service immediately.
Correct Answer: C - Decline the chemical service, document the
contraindications, and refer the client to a dermatologist or
physician.
RATIONALE
Scalp abrasions and a history of allergic reaction are contraindications
to chemical relaxing; barbers must not perform services that could
cause harm and should refer when medical evaluation is indicated.
Patch testing does not address open lesions, and no-lye formulas still
contain chemicals that can cause reactions.
Question 3
A barber is designing a sanitation plan for a new shop. Which combination of
practices is required by the Virginia Board for Barbers and Cosmetology for
wet disinfection of non-electrical implements?
A. Clean with soap and water, then soak in a 10% bleach solution for 5
minutes.
B. Clean with a detergent, rinse, then fully immerse in an EPA-registered
disinfectant for the manufacturer's contact time.
C. Wipe with a disinfectant wipe, then store in a sealed container.
D. Spray with a disinfectant, then place in a UV cabinet for 20 minutes.
Correct Answer: B - Clean with a detergent, rinse, then fully
immerse in an EPA-registered disinfectant for the manufacturer's
contact time.

, RATIONALE
The Virginia Board requires cleaning with detergent and water to
remove debris, followed by complete immersion in an EPA-registered
disinfectant for the specified contact time. Wipes, sprays, and UV
cabinets are not substitutes for full immersion of non-electrical
implements.
Question 4
Which statement accurately describes the chemical process of permanent
waving and its effect on hair bonds?
A. The waving lotion breaks hydrogen bonds, and the neutralizer reforms
them in the new shape.
B. The waving lotion breaks disulfide bonds, and the neutralizer reforms
them in the new shape.
C. The waving lotion breaks peptide bonds, and the neutralizer reforms
them in the new shape.
D. The waving lotion breaks salt bonds, and the neutralizer reforms them
in the new shape.
Correct Answer: B - The waving lotion breaks disulfide bonds,
and the neutralizer reforms them in the new shape.
RATIONALE
Permanent waving reduces disulfide bonds with a reducing agent
(waving lotion) and then reforms them with an oxidizing agent
(neutralizer) to lock in the curl. Hydrogen, peptide, and salt bonds are
not the primary bonds altered in permanent waving.
Question 5
A barber must select a shear for slide cutting and point cutting. Which blade
characteristic is most critical for these techniques?
A. Micro-serrated edge to grip hair during cutting.
B. Convex edge for smooth, sharp cuts and reduced tissue trauma.
