1. 1A nail technician wipes the manicure table with an EPA-registered disinfectant whose label lists a 10-minute contact time. After 5 minutes the surface is already dry. What should the technician do?

   1. A. Begin the service, because the disinfectant has already been in contact with the surface
   2. B. Apply more of the disinfectant so the surface stays visibly wet for the full 10 minutes
   3. C. Wipe the surface with a dry paper towel to remove the remaining disinfectant residue
   4. D. Spray the surface with isopropyl alcohol to cover the remaining 5 minutes of contact

   Answer: B

   Explanation: EPA explains that "The surface should be visibly wet for the entire contact time." and gives the example: "If after 5 minutes the surface is not visibly wet, more product should be applied to the surface." A surface that dried early has not received the labeled contact time, so the technician must re-apply the same disinfectant rather than start the service or switch to another product.

   Reference: Selected EPA-Registered Disinfectants (U.S. EPA) — Section 'What is a Disinfectant Product Label?', Directions for Use, contact time paragraph

2. 2A cuticle softener used for manicures has a label that includes a product description in French alongside the English text. Under FDA cosmetic labeling rules, what must also be true of this label?

   1. A. All statements required by regulation must also appear in French
   2. B. Only the product name must also appear in French
   3. C. The required English statements may be left off the label
   4. D. The French text must appear only on a separate leaflet

   Answer: A

   Explanation: FDA's Cosmetics Labeling Guide states: "Foreign Language Statements: If the label contains any foreign language representation, all statements required by regulation must also appear on the label in the foreign language." The required English statements stay on the label as well.

   Reference: Cosmetics Labeling Guide (FDA) — Section 'Foreign language statements'

3. 3While preparing the station for a new client, a nail technician notices dried product residue and dust on the table. The disinfectant label does not mention pre-cleaning. What should the technician do before applying the disinfectant?

   1. A. Wash the surface with soap and water first, because it is visibly dirty
   2. B. Apply the disinfectant directly, because the label does not ask for pre-cleaning
   3. C. Apply the disinfectant twice in a row, without any cleaning in between
   4. D. Wipe the surface with acetone first to dissolve the dried product residue

   Answer: A

   Explanation: EPA's third step for disinfectant use is: "Make sure to wash the surface with soap and water if the directions mention pre-cleaning or if the surface is visibly dirty." Visible soil triggers pre-cleaning even when the label does not mention it, so the technician washes the table before disinfecting.

   Reference: 6 Steps for Safe & Effective Disinfectant Use (U.S. EPA) — Step 3: Pre-clean the surface

4. 4Before a nail tip application, a technician checks the label on a professional-use nail adhesive. According to OSHA, which information must a professional-use nail salon product provide at minimum?

   1. A. An expiration date printed beside the batch number
   2. B. The name and address of the manufacturer or distributor
   3. C. A full ingredient list in descending order of predominance
   4. D. An approval seal from a state cosmetology board

   Answer: B

   Explanation: OSHA states: "At minimum, professional-use nail salon products must provide the following information:" and lists first "The name and address of the product manufacturer or distributor." followed by an identity statement, directions for safe use, and warnings. FDA does not require an ingredient list on products used only in salons, and no state seal is required.

   Reference: Health Hazards in Nail Salons - Chemical Hazards (OSHA) — Where to Find Information about the Chemicals Found in Nail Salon Products, product label list

5. 5Under the NIC national practical standard, which requirement applies to the monomer liquid that a candidate brings for the sculptured nail?

   1. A. It may be poured into a labeled dappen dish before the section starts
   2. B. It may have any odor level if its container is labeled in English
   3. C. It must be low-odor and factory sealed in its original labeled container
   4. D. It may be kept in a refillable bottle with a handwritten English label

   Answer: C

   Explanation: The NIC practical bulletin states: "Monomer must be low-odor/less-odor and factory sealed in its original container with manufacturer’s label." The section instructions repeat: "You must use a low-odor/less-odor product." Pre-poured, refillable, or handwritten-label containers do not meet the requirement.

6. 6The safety data sheet for the acetone used to remove sculptured nails tells the user to wear impervious gloves. What limitation of safety data sheets does OSHA point out in this kind of instruction?

   1. A. It may not specify the glove material the user actually needs
   2. B. It applies only to employers and never to licensed technicians
   3. C. It replaces the warnings printed on the product's own label
   4. D. It is advisory only, because SDS statements are not reviewed

   Answer: A

   Explanation: OSHA explains: "SDSs may not contain all of the information needed to adequately protect yourself, e.g., the manufacturer may state "wear impervious gloves" without specifying the type of glove material needed." The technician may need to look further to choose a glove that holds up to the product.

7. 7A nail technician checks the products in the first aid kit before demonstrating the blood exposure procedure. Under FDA's OTC monograph, which statement of identity marks a product meant to help prevent infection in a minor cut?

   1. A. Hand sanitizer
   2. B. First aid antiseptic
   3. C. Hospital disinfectant
   4. D. Skin protectant

   Answer: B

   Explanation: FDA's monograph requires that the labeling "identifies the product as a “first aid antiseptic.”" and defines that product as one "applied topically to the skin to help prevent infection in minor cuts, scrapes, and burns." Hospital disinfectants are for surfaces, not skin.

   Reference: OTC Monograph M003: First Aid Antiseptic Drug Products for Over-the-Counter Human Use (FDA) — § M003.50(a) Statement of identity; § M003.3(b) definition

8. 8Before seating a client, a nail technician chooses a product to wipe down the manicure table. Which product meets the national standard for disinfecting the work area?

   1. A. An EPA-registered sanitizer labeled to kill bacteria on hard, nonporous surfaces
   2. B. An FDA-regulated alcohol hand sanitizer labeled to kill germs on the skin
   3. C. An EPA-registered disinfectant labeled bactericidal, virucidal, and fungicidal
   4. D. A detergent cleaner labeled to remove dirt and organic matter from surfaces

   Answer: C

   Explanation: The NIC content outline requires that the candidate disinfect the work area with a product that is "EPA-registered disinfectant that is bactericidal, virucidal, and fungicidal". A sanitizer does not meet that standard because, as EPA explains, "Sanitizing kills bacteria on surfaces using chemicals. It is not intended to kill viruses." Hand sanitizer is made for skin, and a detergent cleaner only removes soil without disinfecting.

9. 9A polish remover is sold only to salons and is used only by technicians on clients; it is never sold at retail. Under FDA rules, must its label carry an ingredient declaration?

   1. A. Yes, because every cosmetic label must list its ingredients
   2. B. No, the ingredient declaration does not apply to salon-only products
   3. C. Yes, because it is labeled as being for professional use only
   4. D. No, unless it is packaged in a bottle larger than 8 fluid ounces

   Answer: B

   Explanation: FDA explains: "The requirement for an ingredient declaration does not apply, for example, to products used only at salons and to free samples." FDA adds that products must list ingredients "if they are also sold at retail, even if they are labeled "For professional use only"", so the professional-use wording alone does not create or remove the requirement.

   Reference: Nail Care Products (FDA) — Section on labeling requirements, ingredient declaration paragraph

10. 10A disinfectant bought from a beauty supply distributor shows EPA Reg. No. 1234-12-567, but the EPA disinfectant list shows only product 1234-12. What does the three-part number tell the nail technician?

    1. A. It is a different formula that EPA has not reviewed for the listed pathogens
    2. B. It is a supplemental distributor product with the same composition and efficacy
    3. C. It is an expired registration that the distributor is still allowed to sell
    4. D. It is a diluted version of the primary product with a longer contact time

    Answer: B

    Explanation: EPA explains: "If your product's registration number has three parts (e.g., 1234-12-123), you have a supplemental distributor product. These products have the same chemical composition and efficacy as primary products." The third part identifies the distributor, so the product can be treated as the listed primary product.
