Green Discoloration Under a Lifted Toe Enhancement
A 42-year-old client comes for a scheduled pedicure with an acrylic overlay on the right great toe. The overlay has lifted at the cuticle, and the natural nail beneath is dark green-black with a slight odor; the client reports no pain or swelling. The nail technician has 30 minutes before the next appointment. The shared foot bath was drained after the previous client but not yet cleaned. The same drill bit was used earlier on another client's acrylic and has only been brushed off. The technician plans to file the discolored area, apply a new acrylic overlay, and use a single-use buffer. The salon uses an EPA-registered hospital-grade disinfectant labeled for 10-minute immersion, and state rules require cleaning before disinfection. The client says she has had this before and it always clears up, and she does not want to see a doctor.
1. What is the likely condition, and should the technician apply a new acrylic overlay today? Explain.
Read the worked answer
The dark green-black discoloration under a lifted enhancement is most consistent with Pseudomonas bacterial colonization, often called green nail syndrome, rather than a simple stain. The lifted overlay creates a warm, moist pocket that supports bacterial growth. Applying a new overlay would trap moisture and bacteria, worsen the condition, and delay medical care. The technician must not diagnose or treat an infection; the scope is to recognize the signs, stop the service, and refer to a physician or podiatrist, especially if pain, swelling, pus, or spreading redness develops. Filing the discolored plate and covering it with acrylic is not appropriate. If salon rules and the technician's license permit removal of the enhancement, removal may be done carefully with infection control, but not treatment of the nail. The client's history of recurrent episodes does not make it safe to proceed, and the 30-minute schedule is irrelevant to the infection-control decision.
2. Outline the correct cleaning and disinfection of the drill bit, foot bath, and single-use items.

Put on clean gloves. The drill bit must first be cleaned with soap and water and brushed to remove all debris, then fully immersed in the EPA-registered hospital-grade disinfectant for the labeled contact time, which here is 10 minutes, then dried and stored covered. Brushing alone is not disinfection. The foot bath must be drained, cleaned of visible debris with detergent and water, then disinfected according to the product label; if a liner is used, discard it as single-use and still clean and disinfect the basin. The single-use buffer, files, cotton, and any porous item that cannot be cleaned and disinfected go into the trash after use. Reusable nippers, if used, require the same clean-then-disinfect sequence. Do not use the same drill bit on the next client until the contact time is complete. Hand hygiene and glove changes are required between clients and after contact with the foot bath.
3. How should the technician communicate with the client and document the encounter?
Read the worked answer
Explain plainly that the green-black color under the lifted acrylic is not normal and should be evaluated by a health care provider before a new enhancement is applied. Avoid diagnosing; say it may be a bacterial condition and that covering it could make it worse. Do not shame the client for waiting or for refusing a doctor. Offer to remove the enhancement only if that is within scope and the client consents, or reschedule the pedicure after medical clearance. Do not perform nail services on the affected toe. Document the visual findings, odor, absence of pain and swelling, the client's statement about previous episodes, the referral, the refusal of medical care, and the services declined. Record the disinfection of the drill bit and foot bath, including product name and contact time. Keep the tone professional and confidential.
