Green Nail, MMA, and a Bleeding Cuticle
A client comes in with a dark green-black discoloration on her right thumbnail that has been present for three weeks. She wants a full set of acrylics to cover it for a vacation. The nail tech files the surface of the nail with a coarse carbide bit on a high-speed electric file, then applies an MMA-based monomer and polymer directly over the discoloration. While prepping, she uses nippers to cut the cuticle until it bleeds, then wipes the nipper with alcohol and continues. The salon's electric file has no dust extraction, and the tech wears no mask or goggles. The client mentions she is a nurse and 'gets these all the time.' The salon uses a single-use nail file that was used on the previous client and wiped with a disinfectant spray.
1. Identify the clinical and infection-control concerns in this scenario and explain the risk of covering the nail.

The green-black discoloration suggests bacterial colonization, commonly Pseudomonas, under the nail plate. Covering it with acrylic seals in moisture and bacteria, can worsen the infection, and can stain the plate. Filing the plate with a coarse bit thins it and can spread organisms. The cuticle nipping until bleeding creates a blood exposure and a portal for infection. Reusing a single-use file and only spraying the nipper with alcohol are cross-contamination breaches; alcohol is not a hospital disinfectant for blood. No mask or goggles with e-file dust is an occupational hazard. MMA is a banned monomer in many states because of nail damage and fumes.
2. Describe the correct service approach and the legal and regulatory issues, including MMA and electric-file use.

Do not apply the enhancement. Refer the client to a physician or dermatologist for evaluation and advise her to keep the nail dry and avoid covering it. Disinfect all implements, discard the single-use file, and follow blood-exposure protocol for the cut. Use only EPA-registered hospital disinfectant after cleaning. Switch to EMA monomer; check state board rules. Use the e-file only with training, low speed, proper bits, and no pressure on the natural nail; avoid the cuticle area. Never cut live tissue; push back cuticles and nip only a hangnail. Wear a mask and eye protection and use dust extraction. Document the referral and the refused service.
3. What should be recorded, and how should the tech communicate with the client?

Record the nail assessment, the discoloration, the services requested and refused, the referral, the blood exposure, the implements used, the disinfection, and the client's understanding. Communicate without diagnosing: 'This looks like something a physician should check; I cannot cover it safely.' Offer a manicure without enhancement after clearance, and explain the salon's policy. Keep the tone nonjudgmental. If the client declines the referral, document that and still decline the acrylic service.
