California Cosmetology Written ExamNail CareMedium
A client requests a manicure and the technician notices a greenish-black discoloration under the free edge with a foul odor. What should the technician do?
- ARefuse service and refer the client to a physician
- BApply an antifungal polish and continue the service
- CSoak the nail in disinfectant before servicing normally
- DProceed with the manicure but avoid the affected nail
Show answer & explanationAnswer & explanation
Correct answer: A. Refuse service and refer the client to a physician
Greenish-black discoloration with odor is characteristic of a bacterial infection (Pseudomonas) or fungal infection, both contraindications for nail services; California regulations require referral to a physician rather than treatment in the salon.
Why the other options are wrong
- B. Cosmetologists are not licensed to diagnose or treat infections.
- C. Disinfectant on the client's skin does not treat an infection and is not a substitute for medical care.
- D. Partial service still risks spreading infection and violates health code.
Nail Infection Contraindication
Signs like green-black discoloration, odor, pus, or swelling indicate infection and require refusal of service with referral to a physician.
- Pseudomonas causes greenish nail discoloration
- Cosmetologists cannot diagnose or treat disease
- Referral protects client and technician from liability
Memory trick: Green nail = 'go to the doctor'
