样题与解析
以下是本题库中的部分真题与完整解析。完整题库请用上方的刷题工具。
- 1. Disinfection & Safety
What is the primary difference between sanitation and disinfection?
- a.They both destroy all microbial life including spores
- b.Sanitation reduces the number of germs to a safe level, while disinfection destroys most pathogens on non-living surfaces
- c.Sanitation destroys pathogens, while disinfection only removes visible dirt
- d.There is no practical difference between the two terms
答案: b
解析: Sanitation lowers the level of germs on a surface to a level considered safe, typically by cleaning with soap and water. Disinfection goes further, destroying most disease-causing organisms on hard non-porous surfaces, though it does not necessarily kill bacterial spores.
依据: CCR Title 16 §979
- 2. Disinfection & Safety
After a blood spill on a workstation surface, the area must be:
- a.Left to air dry with no cleaning
- b.Covered with a towel and used again
- c.Cleaned and then disinfected with an EPA-registered disinfectant effective against bloodborne pathogens (tuberculocidal or equivalent)
- d.Sprayed only with water
答案: c
解析: Any surface contaminated with blood must be cleaned of visible matter and then disinfected with a product labeled effective against HIV, HBV, and other bloodborne pathogens. Contaminated disposable materials must be double-bagged or placed in a proper container.
依据: CCR Title 16 §979
- 3. Disinfection & Safety
Good ventilation in a barbershop is important because it:
- a.Reduces buildup of chemical fumes and airborne particles
- b.Increases the strength of disinfectants
- c.Eliminates the need to clean tools
- d.Makes hair grow faster
答案: a
解析: Proper ventilation removes vapors from products such as disinfectants, aerosols, and chemical services, protecting the respiratory health of workers and clients. It does not replace disinfection or cleaning duties.
依据: Cal/OSHA General Industry Safety Orders
- 4. Haircutting & Shaving
On a clipper, a longer guard (attachment comb) will:
- a.Cut the hair shorter
- b.Leave the hair longer
- c.Remove the blade
- d.Have no effect on length
答案: b
解析: The guard, or attachment comb, holds the blade farther from the scalp, so a higher-numbered guard leaves more length. Removing the guard cuts closest to the skin.
- 5. Haircutting & Shaving
'Stropping' a straight razor is done to:
- a.Sharpen a very dull blade from scratch
- b.Clean hair from the blade
- c.Smooth, align, and finish the edge just before shaving
- d.Add a disinfectant coating
答案: c
解析: Stropping draws the blade across a leather or canvas strop to true and polish the already-honed edge, aligning the fine metal for a smooth cut. Unlike honing, stropping removes little to no metal and is done right before use.
- 6. Haircutting & Shaving
A 'guideline' in haircutting is:
- a.A line painted on the floor
- b.The first section cut to a chosen length that all following sections are matched to
- c.The manufacturer's warranty
- d.A rule about pricing
答案: b
解析: The guideline (or guide) is the initial cut length that serves as a reference for every subsequent section, keeping the haircut consistent. Losing the guideline leads to uneven length across the head.
- 7. Hair & Scalp Sciences
The active growing phase of the hair growth cycle is called:
- a.Telogen
- b.Anagen
- c.Catagen
- d.Keratin
答案: b
解析: Anagen is the phase of active growth during which the hair is being produced, and it can last several years. Catagen is the brief transition phase and telogen is the resting/shedding phase.
- 8. Hair & Scalp Sciences
Hair elasticity, the ability of hair to stretch and return, is determined mainly by bonds in the:
- a.Cortex
- b.Cuticle
- c.Medulla
- d.Sebaceous gland
答案: a
解析: The cortex contains the hydrogen and disulfide bonds that give hair its strength and elasticity. Damaged cortex bonds leave hair weak and prone to breakage.
- 9. Chemical Services
A permanent wave (perm) changes the hair by:
- a.Only wetting the hair
- b.Removing pigment
- c.Breaking and then reforming the disulfide bonds around a rod to create curl
- d.Coating the cuticle with wax
答案: c
解析: A perm uses a waving lotion to break disulfide bonds while the hair is wrapped on rods, then a neutralizer reforms the bonds in the new curled shape. The size of the rod determines the tightness of the curl.
- 10. California Law
In California, barbering is regulated under the Barbering and Cosmetology Act by the:
- a.Department of Motor Vehicles
- b.Board of Barbering and Cosmetology
- c.Federal Trade Commission
- d.Local police department
答案: b
解析: The California Board of Barbering and Cosmetology, within the Department of Consumer Affairs, licenses and regulates barbers and shops. It enforces the Barbering and Cosmetology Act and its regulations in the Business & Professions Code and CCR Title 16.
