Thickened Yellow Nail and a Broken Autoclave
A 47-year-old regular client arrives for a 45-minute pedicure. On the right big toe the nail plate is thickened, yellow-brown and lifting at the free edge, with crumbling debris underneath. The skin between the fourth and fifth toes is white, macerated and itchy. She says it has been like this "since winter" and asks you to apply a dark gel polish because her daughter's wedding is in three days. The salon autoclave has been sent for servicing and will not be back until next week. The only available disinfection is a 70% alcohol spray and a UV cabinet; the foot spa has a removable filter that was cleaned yesterday. A junior therapist has already filled the basin and laid out a shared nail file and nipper. The client is otherwise healthy and not on medication. She has no open wound on the foot.
1. Should the pedicure go ahead? Justify your decision using infection-control principles and the limits of salon practice.

The pedicure should not go ahead on the affected foot. The nail signs - thickening, yellow-brown discolouration, onycholysis and subungual debris - plus macerated, itchy toe-web skin strongly suggest a fungal infection. A therapist cannot diagnose this, but must treat it as potentially infectious. Filing, cuticle work and massage can spread scales and spores to tools, the basin and the therapist's hands. Gel polish would also seal in moisture and hide the condition, making later assessment harder.
The missing autoclave is a second, independent reason to stop. A 70% alcohol spray and a UV cabinet are not sterilisation, and alcohol is unreliable against fungal spores. Without validated reprocessing, reusable files and nippers cannot be safely used on another client. The correct decision is to explain the findings, decline the service on that foot, and document the refusal and advice given.
2. Describe the correct decontamination procedure for the tools and foot spa after this client, including what should happen to the items already laid out.

Decontamination is a two-stage process: clean first, then disinfect or sterilise. Visible debris and biofilm must be removed with detergent and a brush before any chemical works. Items already laid out but not used should be returned to clean storage; anything that touched the foot must be processed. Single-use files and buffers should be disposed of in a covered waste bin, not sprayed and reused.
For reusable metal nippers and scissors, cleaning must be followed by sterilisation in a validated autoclave. Because the autoclave is unavailable, those items should be removed from service until it returns. The foot spa must be drained, cleaned with detergent, then disinfected with a product approved by the manufacturer at the correct dilution and contact time; the removable filter needs the same treatment. A 70% alcohol spray is not a substitute for a validated disinfectant, and a UV cabinet is storage, not sterilisation. The junior therapist should also be shown why the pre-set trolley was unsafe.
3. What advice and referral should the client receive, and how should the wedding request be handled?
Read the worked answer
Advise the client to see her GP or a podiatrist/chiropodist for assessment and treatment; antifungal treatment may be needed for months. Explain that polish should not be applied over a suspected infected nail because it traps moisture and disguises changes. She should not share towels, socks or nail tools at home, should dry between the toes carefully, and should wear breathable footwear.
For the wedding, be empathetic but firm: offer a file and polish on the unaffected toes only if tools can be properly reprocessed or single-use items are available, and keep all equipment separate. Do not polish the affected nail. Offer an alternative such as a hand massage or manicure, and suggest she speak to a pharmacist about cosmetic camouflage only after medical advice. Record the refusal, the reason, the referral and the client's response in the consultation record.
