1. 1Which activity claim distinguishes Oregon's definition of a high-level disinfectant from its low-level disinfectant definition?

   1. A. Tuberculocidal
   2. B. Bactericidal
   3. C. Fungicidal
   4. D. Limited virucidal

   Answer: A

   Explanation: Tuberculocidal is correct because Oregon's high-level definition requires "demonstrated tuberculocidal activity" plus EPA registration. Bactericidal, fungicidal, and limited virucidal are genuine activity claims found in the low-level definition, so they are credible adjacent classifications but do not distinguish the high level.

2. 2Which sink location is excluded as a qualifying water source for an Oregon cosmetology facility located in a residence?

   1. A. Dispensing area
   2. B. Facility work area
   3. C. Restroom
   4. D. Shampoo area

   Answer: C

   Explanation: Restroom is correct because Oregon states: "Sinks in the restroom do not qualify as a water source for a facility located within a residence." The other choices are plausible facility locations but are not the location expressly excluded by this rule.

   Reference: Cos Rules — OAR 817-007-0075(3)

3. 3Who is responsible for determining whether a practice is prohibited under Oregon's cosmetology practice standards?

   1. A. The client receiving the service
   2. B. The certificate or registration holder
   3. C. The product manufacturer
   4. D. The facility's landlord

   Answer: B

   Explanation: The certificate or registration holder is correct because Oregon states: "An authorization holder is responsible for determining if any practice would be prohibited by law." A client, manufacturer, or landlord does not carry that duty.

   Reference: Cos Rules — OAR 817-120-0005(3)

4. 4In an Oregon shared facility, who is responsible for the cleanliness and sanitary condition of common areas?

   1. A. The most senior authorization holder
   2. B. The facility license holder
   3. C. Each authorization holder
   4. D. A designated independent contractor

   Answer: C

   Explanation: Each authorization holder is correct because Oregon states: "All shared or common areas must be clean and sanitary and are the responsibility of each authorization holder." The other choices are genuine facility actors but improperly narrow the shared responsibility.

5. 5What minimum percentage is required to pass each Oregon Board of Cosmetology examination?

   1. A. 70 percent
   2. B. 75 percent
   3. C. 80 percent
   4. D. 85 percent

   Answer: B

   Explanation: Seventy-five percent is correct because Oregon's examination rule sets that minimum for each written examination. The other percentages are not the rule's passing threshold.

   Reference: Cos Rules — OAR 817-006-0075(3)

6. 6Unless otherwise specified, when does a newly issued Oregon Health Licensing Office authorization become not current?

   1. A. On the last day of the month one year after issuance
   2. B. On the last day of the month two years after issuance
   3. C. On the last day of the month three years after issuance
   4. D. On the last day of the month four years after issuance

   Answer: B

   Explanation: The last day of the month two years after issuance is correct for a certificate issued under Oregon's cosmetology statutes. The other time periods do not match the cited HLO rule's certificate term.

   Reference: Hlo Rules — OAR 331-030-0010(4)

7. 7When one gallon or less of each reactive chemical is stored in the same Oregon facility cabinet, what minimum separation is given as the rule's example?

   1. A. 6 inches
   2. B. 12 inches
   3. C. 18 inches
   4. D. 24 inches

   Answer: B

   Explanation: Twelve inches is correct because Oregon gives separation "for example at least 12 inches apart or on different shelves" when the stated small quantities share storage. The other distances are not the rule's example.

   Reference: Cos Rules — OAR 817-060-0020(5)(a)

8. 8Which Oregon disinfectant classification requires bactericidal, germicidal, fungicidal, and limited virucidal activity?

   1. A. High-level disinfectant
   2. B. Low-level disinfectant
   3. C. Chemical sterilant
   4. D. Skin antiseptic

   Answer: B

   Explanation: Low-level disinfectant is correct because Oregon defines it as a chemical agent with "bactericidal, germicidal, fungicidal, and limited virucidal activity" that is EPA registered. The other classifications describe different antimicrobial uses or levels.

   Reference: Cos Rules — OAR 817-005-0005(26)

9. 9Whom must an Oregon cosmetology facility license holder allow to inspect the facility or conduct an investigation?

   1. A. The Office's representative
   2. B. An Oregon OSHA compliance officer
   3. C. A local fire-code inspector
   4. D. A county public-health inspector

   Answer: A

   Explanation: The Office's representative is correct because the facility standard requires the holder to "Allow the Office’s representative to inspect the facility or conduct an investigation." The other choices are genuine public inspection roles, but they are not the actor to whom this particular HLO rule assigns that access.

   Reference: Cos Rules — OAR 817-007-0050(1)(b)

10. 10Which government level is included with city, county, and state requirements that Oregon authorization holders must observe?

    1. A. City, county, state, and federal
    2. B. City, county, state, and tribal
    3. C. City, regional, state, and federal
    4. D. Municipal, county, territorial, and federal

    Answer: A

    Explanation: City, county, state, and federal is correct because Oregon requires authorization holders to observe applicable "city, county, state and federal regulations and requirements." Each distractor substitutes another genuine governmental level for one level in the controlling four-part sequence.
