California Cosmetology Written ExamClient Consultation and AnalysisMedium
A client checks in for a scheduled manicure. The cosmetologist notices thin, thread-like burrow lines and intense itching between the client's fingers and wrists, worsening at night. What is the most likely cause, and what should the cosmetologist do?
- AScabies; refuse service and refer the client to a physician
- BTinea Corporis; proceed with service using gloves
- CPsoriasis; proceed since it is non-contagious
- DContact dermatitis; apply hand lotion and proceed
Show answer & explanationAnswer & explanation
Correct answer: A. Scabies; refuse service and refer the client to a physician
Scabies is a highly contagious skin infestation caused by the itch mite (Sarcoptes scabiei), producing thin burrow lines and severe itching, especially at night, in the webs of the fingers and wrists. Because it spreads easily through skin contact, service must be refused and the client referred to a physician for treatment.
Why the other options are wrong
- B. Tinea Corporis (ringworm of the body) presents as ring-shaped patches, not burrow lines.
- C. Psoriasis presents as silvery scaly patches, not burrow marks, and scabies is in fact contagious.
- D. Contact dermatitis does not produce thread-like burrows and is not typically worse at night.
Scabies
A highly contagious skin condition caused by the itch mite burrowing under the skin, producing threadlike burrow tracks and intense itching, especially at night.
- Caused by the mite Sarcoptes scabiei, spread by skin-to-skin contact.
- Common sites include finger webs, wrists, and elbows.
- Service must be refused and the client referred to a physician; it is not treated in the salon.
Memory trick: Scabies mites 'scribble' burrow lines under the skin at night.
