After at least 10 minutes of circulation, drain, rinse, dry with a new clean paper towel, and log the cleaning.Option B: Treating only the rim does not disinfect the circulating basin system required by this rule.Option C: Drying without the disinfectant cycle skips the required step; final drying happens only after disinfection and rinsing.Option D: The disinfectant must circulate for at least 10 minutes; five minutes is too short.2 / 25 Consultation and nail analysis In a nail-anatomy review, a technician is asked which structure produces the nail plate. What should they identify? Choose one answer

Emery boards are listed among client-contact supplies that cannot be disinfected and must be discarded immediately after use on a single client.6 / 25 Consultation and nail analysis During pedicure consultation, the technician sees an open scrape on the client’s heel where the planned exfoliation would occur. What is the proper decision for that area? Choose one answer

Answer and explanations Correct answer: C. Postpone heel exfoliation until the skin has healed.
Option A: Gauze does not permit service over the client’s broken skin; the rule’s covering exception concerns the worker’s own hands.Option B: Changing to massage still means performing a service on the broken skin.Option C · Correct answer: Correct. California §984(e) prohibits service on broken skin; reassess the skin before resuming.Option D: A single-use foot file does not permit service on broken skin.7 / 25 Skin care A client requests a hand and lower-arm massage as part of a manicure.

Answer and explanations Correct answer: B. Buff or file; soak if directed, then remove.
Option A: Pulling or peeling gel off tears layers from the natural nail; removal follows the product directions.Option B · Correct answer: Correct. For this damaged enhancement, prepare and remove the gel according to the product directions, which determine whether soaking is used. In California, discard a file or buffer that cannot be disinfected immediately after this client (§981(a)).Option C: Gel products differ, so removal follows the particular product's instructions rather than one standard soak time.Option D: Layering over damaged gel leaves the damage in place and does not meet the client's request for removal.9 / 25 Safety and infection control A pipe-less footspa has a removable footplate. After a pedicure, the technician drains the basin. What must happen before the disinfectant is circulated? Choose one answer

Answer and explanations Correct answer: D. Leave the nail untreated; suggest a medical opinion.
Option A: Digging out the embedded nail corner would be treating the ingrown toenail, outside the manicurist’s scope.Option B: Declining is appropriate, but home-treatment advice is not the medical opinion listed in the consultation outline.Option C: More experience does not expand a nail technician’s scope to treating an ingrown toenail.Option D · Correct answer: Correct. The Board excludes treatment of ingrown toenails from manicurist scope; the PSI consultation outline lists recommending a medical opinion.11 / 25 Skin care A client wants a pedicure exfoliation that removes living tissue below the epidermis.

Answer and explanations Correct answer: C. Brush away the excess powder before the next dip.
Option A: Loose excess powder is brushed off between dips, not built into the nail.Option B: Powder layers are built first; top coat belongs to the finishing steps.Option C · Correct answer: Correct. Brushing off loose powder finishes this layer so the next dip bonds evenly, and the separate portion keeps the jar uncontaminated as Art.12 §988(c) requires.Option D: Filing and buffing belong to finishing; between dips, loose powder is simply brushed off.13 / 25 Safety and infection control Before using a new nail monomer, a technician wants its signal word and warning pictograms.

Answer and explanations Correct answer: D. Use an OTC peel according to its directions.
Option A: Consent does not make a physician-only exfoliant permissible.Option B: Skin thickness does not remove the product restriction.Option C: Mixing does not turn a physician-only product into an allowed one.Option D · Correct answer: Correct.

California §989(b) prohibits methyl methacrylate monomer in establishments and schools, regardless of the narrower federal position.Option D: The California rule identifies methyl methacrylate monomer; it does not ban every acrylic monomer.18 / 25 Consultation and nail analysis During nail analysis, a trainee points to the tissue directly beneath most of the attached nail plate.
