1. 1A Louisiana barber advertises a service outcome that the barber knows is false. Which licensing consequence is authorized by the barber law?

   1. A. The board may refuse, suspend, or revoke the certificate
   2. B. The board may require a corrective advertisement before acting on the certificate
   3. C. The board may convert the certificate to probation automatically
   4. D. The board may defer all certificate action until the next renewal

   Answer: A

   Explanation: The statute says, "The board may refuse to issue, renew, suspend, or revoke any certificate of registration" and lists "Advertising by means of false or deceptive statements." The knowingly false advertisement therefore exposes the certificate to those disciplinary actions.

   Reference: Rs 37 372 — R.S. 37:372 introductory paragraph and (4)

2. 2After reusable shears are used on a patron, when must Louisiana-required reprocessing occur?

   1. A. After that use and before the shears are reused
   2. B. Immediately before serving the next customer
   3. C. Once each day before the shop closes
   4. D. After an exposure period greater than ten minutes

   Answer: A

   Explanation: The rule states, "The sterilization of all tools and instruments shall be accomplished after use on each customer and before tools and instruments are re-used." The other timings are real neighboring sanitation timings for hand cleansing, daily treatment of specified items, or chemical contact, but they do not replace the tool-between-patrons rule.

   Reference: Lac Title 46 Part Vii — LAC 46:VII §§119

3. 3Immediately before serving each customer, how must a Louisiana barber clean the barber's hands?

   1. A. Thoroughly with soap and water
   2. B. With an ultraviolet cabinet intended for instruments
   3. C. With water alone followed by a clean towel
   4. D. With disinfectant solution only after the service

   Answer: A

   Explanation: The rule states, "Each barber shall cleanse his hands thoroughly with soap and water immediately before serving each customer." Soap-and-water cleansing at that time is mandatory.

   Reference: Lac Title 46 Part Vii — LAC 46:VII §109(B)

4. 4A removable hairpiece is repeatedly clipped to the same area of a client's natural hair. Which risk should the barber discuss?

   1. A. Breakage and traction-related hair loss
   2. B. Temporary flattening without hair breakage
   3. C. Increased shaft diameter at the clip site
   4. D. Accelerated anagen growth at the clip site

   Answer: A

   Explanation: The NLM-hosted review states, "clips used at the same site may cause breakage of the existing hair" and that tugging by a hairpiece "may precipitate traction alopecia." Repeated attachment at one site creates both risks.

5. 5When may a shaving brush be used for more than one person in a Louisiana shop?

   1. A. After proper sterilization between people
   2. B. After cleaning without sterilization between people
   3. C. After cabinet storage without sterilization between people
   4. D. After changing the mug without sterilizing the brush

   Answer: A

   Explanation: The rule prohibits "the use of neck dusters, shaving mugs and shaving brushes in common, or for more than one person without proper sterilization." Proper sterilization is therefore the condition for reuse on another person.

   Reference: Lac Title 46 Part Vii — LAC 46:VII §121(D)

6. 6A client has an itchy, scaly, ring-shaped scalp rash. Which type of organism causes the condition commonly called ringworm?

   1. A. Fungus
   2. B. Virus
   3. C. Bacterium
   4. D. Parasitic worm

   Answer: A

   Explanation: CDC states, "Ringworm is caused by fungi (not a worm)." Fungus is therefore the organism category that causes ringworm.

7. 7Which layer makes up most of the hair shaft and strongly influences its mechanical properties?

   1. A. Cortex
   2. B. Medulla
   3. C. Cuticle
   4. D. Inner root sheath

   Answer: A

   Explanation: NCBI states, "The bulk of this hair fiber belongs to the cortical layer, which plays a vital role in determining the physical and mechanical properties of the hair." The cortex is therefore the shaft layer described.

8. 8Which ingredient name indicates that a smoothing product contains or releases formaldehyde according to FDA?

   1. A. Methylene glycol
   2. B. Sodium chloride
   3. C. Citric acid
   4. D. Glycerin

   Answer: A

   Explanation: FDA says that if a product lists "formaldehyde, formalin, or methylene glycol, then it means the product contains formaldehyde or will release formaldehyde." Methylene glycol is therefore the indicator among these names.

9. 9How much written notice must a new Louisiana barber shop give the board before initially opening?

   1. A. At least 30 days

    2. B. On or before March 31
    3. C. On or before June 30
    4. D. On or before December 31

    Answer: A

    Explanation: The statute says, "All certificates of registration shall expire at midnight on January 31 of each year and shall be renewed on or prior to that date." Renewal is therefore due on or before January 31.
