Nail disorders: when to refuse the service

The exam does not ask you to diagnose. It asks you to sort what you see into two piles: conditions you may work over, and conditions that end the appointment with a referral. The sorting rule is whether there is any sign of infection or inflammation.

Questions and answers, explained

All 9 questions above, with the correct answer and why it is correct. Everything here is on nail disorders: when to refuse the service.

1. A client's toenail is thickened, discolored and crumbling at the edge. What should the cosmetologist do?

   • ADecline to service that nail and refer her to a physicianCorrect
   • BFile the damaged area smooth and apply a polish over it
   • CSoak the nail in an antifungal solution before continuing
   • DService the nail using implements reserved for that client

   Why: Thickening, discoloration and crumbling suggest a fungal infection, which is a disease rather than a disorder — it is not serviced, not treated, and the client is referred. Filing or polishing over it spreads spores through the salon and hides the problem. Soaking in an antifungal is treating a condition, which is outside the license.

2. A cosmetologist declines to service a client with a visible contagious condition. How should this be handled?

   • ABy explaining loudly enough that waiting clients understand the delay
   • BBy naming the condition so the client knows what to tell a doctor
   • CBy completing the service and privately disinfecting afterwards
   • DPrivately and courteously, referring the client to a physicianCorrect

   Why: The refusal is necessary but the client's dignity is not optional: the conversation happens quietly, without a diagnosis, and ends with a referral. Naming the condition is diagnosing, which a cosmetologist may not do. Announcing it publicly humiliates the client, and performing the service anyway exposes the operator, the implements and everyone who follows.

3. Which nail condition may be serviced in the salon?

   • AOnychophagy, or bitten nailsCorrect
   • BParonychia, with swelling and pus at the nail fold
   • COnychomycosis of the nail plate
   • DAn ingrown nail with visible inflammation

   Why: Bitten nails are a disorder — a change in the nail's condition with no infection present — so the nail may be serviced and improved. Paronychia and onychomycosis are infections, and an inflamed ingrown nail is a medical problem; all three are referred. Disorder versus disease is the single most tested idea in this domain.

4. Before using any product on a client for the first time, what should be confirmed?

   • AThat the product is the salon's current retail bestseller
   • BThat the container has been opened within the last month
   • CThat the client has used a similar product at home before
   • DAny known allergies or sensitivities the client hasCorrect

   Why: The consultation asks about known allergies and sensitivities before any product touches the client, and that answer is recorded. Prior home use of something similar proves nothing about this formula. How well a product sells and how recently the container was opened are irrelevant to whether this client can safely receive it.

5. Why does a client with diabetes require extra caution during a pedicure?

   • AReduced sensation and slower healing make small injuries seriousCorrect
   • BPolish and enhancement products are absorbed more readily
   • CThe nails grow considerably faster than average
   • DWarm water causes an immediate drop in blood sugar

   Why: Reduced sensation means a client may not feel a cut or a too-hot soak, and impaired circulation means a minor break in the skin can become a serious infection. Water temperature is checked carefully, cutting is avoided, and anything abnormal is referred. Nail growth rate and product absorption are not the concern, and warm water does not affect blood sugar that way.

6. What are the white spots sometimes visible on a nail plate?

   • ALeukonychia, usually caused by minor trauma to the matrixCorrect
   • BAn early stage of fungal infection requiring referral
   • CA calcium deficiency that a supplement would correct
   • DSeparation of the plate from the nail bed

   Why: Leukonychia is a harmless disorder, generally the result of a small knock to the matrix while the nail was forming, and the nail may be serviced normally. Attributing it to a calcium deficiency is a persistent myth and would amount to giving nutritional advice. Separation of the plate from the bed is onycholysis, a different condition that does require referral.

7. What is examined before a manicure begins?

   • AThe nails and the surrounding skin, for disorders or infectionCorrect
   • BOnly the nail plates, since the skin is not being serviced
   • COnly the nails that the client wishes to have polished
   • DNothing, provided the client reports no problems

   Why: The whole nail unit and the surrounding skin are examined, because infection frequently presents in the nail folds rather than on the plate itself. Examining only the plates or only the nails to be polished misses exactly where paronychia appears. A client who reports nothing may still have something visible.

8. A nail plate has separated from the bed at the free edge without any sign of infection. What is this called?

   • AOnycholysisCorrect
   • BOnychophagy
   • CLeukonychia
   • DParonychia

   Why: Onycholysis is separation of the plate from the bed, and because the exposed bed is vulnerable to infection the client is referred rather than serviced on that nail. Onychophagy is nail biting, leukonychia is white spotting, and paronychia is an infection of the tissue around the nail — each a distinct condition with a distinct response.

9. Horizontal ridges running across a client's nail plate most likely indicate what?

   • AA past interruption to nail growth at the matrixCorrect
   • BAn active fungal infection of the nail plate
   • CHabitual use of an electric file at too high a speed
   • DInsufficient protein in the client's diet

   Why: Horizontal ridges reflect a temporary disturbance at the matrix — illness, injury or a systemic event — that has since grown out along the plate. The nail may be serviced gently, and persistent or severe ridging is referred. Fungal infection presents as thickening and discoloration, and commenting on diet would be offering nutritional advice.
