Green Discoloration Under an Acrylic Enhancement
A client comes for a fill on acrylic nails. The nail technician notices the right index fingernail has a dark green-black discoloration under the enhancement, and the natural nail plate looks slightly lifted. The client says it started after she glued down a loose nail at home. She has no pain or pus. The technician plans to file off the enhancement, buff the green area away, apply a new acrylic, and finish with a top coat. She uses a reused 180-grit file and a metal cuticle pusher that was wiped with a towel after the last client. The salon's disinfectant jar is cloudy, and the label has worn off.
1. Identify the likely condition and explain whether the technician should perform the service as planned.
Read the worked answer
The green-black discoloration under a lifted enhancement is consistent with a bacterial infection, often called green nail or Pseudomonas. Moisture trapped under the lifted acrylic creates a warm, dark environment for bacteria. The technician should not file, buff, or cover it. Buffing can spread bacteria and damage the natural nail plate, and applying a new enhancement traps moisture and bacteria. The client should be referred to a physician for evaluation, especially because the nail is lifted. The technician can explain what she sees without diagnosing, and should not puncture, cut, or treat the area. The service should be declined until the client provides medical clearance.
2. What sanitation corrections are required for the file, cuticle pusher, and disinfectant jar?
Read the worked answer
The 180-grit file is porous and cannot be reliably disinfected, so it should be discarded after use on this client or, if it was used before, removed from service. The metal cuticle pusher must be cleaned with soap and water, dried, and immersed in an EPA-registered hospital-grade disinfectant for the label contact time; wiping with a towel is only cleaning, not disinfection. The cloudy, unlabeled jar is a serious problem: the product cannot be assumed to be at the correct dilution or contact time, and an unlabeled container violates basic safety practice. The jar should be emptied, cleaned, and refilled with a properly labeled disinfectant mixed at the label dilution. The salon should establish a schedule for changing the solution and logging it.
3. How should the technician explain the situation to the client and document it?
Read the worked answer
The technician should use plain language: there is a discoloration under the lifted nail that may be an infection, and it is not something a nail technician can diagnose or treat. She should explain that covering it could make it worse and that the client should see a health care provider. She should not promise a diagnosis or recommend a medication. The salon should document the date, the observed discoloration, the lifted enhancement, the referral, and the refusal to service. The record should also note that the file was discarded and the pusher disinfected. If the client returns with medical clearance, the technician can reassess the nail plate and proceed only if it is intact and healthy.
