Washington Cosmetology License Exam — All Questions

A nail file, buffer, or wooden orangewood stick has been used on one client. What do Washington rules require next?

• a.Disinfect it and reuse it on the next client
• b.Wash it with soap and water and keep using it
• c.Discard it — porous, single-use items cannot be disinfected and must not be reused✓
• d.Store it in a UV drawer to sterilize it for reuse

Porous and disposable items — nail files, buffers, orangewood/cuticle sticks, disposable wax applicators, and similar — absorb moisture and cannot be reliably disinfected. Washington rules require these to be used on one client and then thrown away. Only non-porous, cleanable implements may be disinfected and reused.

During a service a client is nicked and bleeds. What is the correct exposure-incident response expected by the Washington State Department of Licensing (DOL)?

• a.Stop, put on gloves and give basic first aid, then clean and disinfect any surfaces and tools that contacted blood and discard contaminated single-use items in a lined container✓
• b.Continue the service and clean up afterward
• c.Reuse the tool on the next client since the blood was minor
• d.Rinse the tool under water and place it back in service immediately

Blood or body-fluid exposure triggers a defined procedure: stop the service, protect yourself with gloves, apply first aid, then clean and disinfect the workstation and any contaminated implements, and dispose of single-use contaminated materials properly. This limits transmission of bloodborne pathogens and is a core public-health duty enforced by the Washington State Department of Licensing (DOL).

Why do Washington sanitation standards prohibit re-dipping a used wax applicator back into the wax pot ('double-dipping')?

• a.It cools the wax too quickly
• b.It wastes product and slows the service
• c.It changes the color of the wax
• d.The applicator carries skin cells and microorganisms into the pot, contaminating the wax for every later client✓

Once a stick touches a client's skin it picks up bacteria and cells; returning it to the pot contaminates all remaining wax. A fresh applicator must be used for each withdrawal of wax. This single-use discipline is why double-dipping is treated as a sanitation violation.

How do Washington rules expect towels, capes, and other linens to be handled in a licensed salon?

• a.One towel per day is fine as long as it looks clean
• b.A clean towel/drape is used for each client, and soiled linens are stored in a closed/covered container away from clean supplies✓
• c.Used towels may be shaken out and reused on the next client
• d.Linens do not need laundering if only used for drying hands

Fresh, laundered linens must be provided for each client, and anything that has touched a client is 'soiled' until laundered. Clean and used linens must be kept separate, with soiled items in a covered receptacle. This prevents cross-contamination between clients.
