A cosmetologist is preparing a client for a facial. The client has an infection characterized by an infestation of parasitic mites that burrow under the skin, causing intense itching and red papules or vesicles, often in a linear pattern. What condition does the client exhibit?
- AScabies
- BHerpes Zoster
- CPsoriasis
- DImpetigo
Show answer & explanationAnswer & explanation
Correct answer: A. Scabies
Scabies is a contagious skin infestation caused by the human itch mite (Sarcoptes scabiei). The mites burrow into the epidermis, causing intense itching, especially at night, and characteristic red papules, vesicles, or linear burrows.
Why the other options are wrong
- B. Herpes Zoster (shingles) is a viral infection that causes a painful rash with blisters in a band-like pattern, not parasitic mites.
- C. Psoriasis is a chronic autoimmune condition causing red, scaly patches, not an infestation by burrowing mites.
- D. Impetigo is a bacterial skin infection characterized by red sores that quickly rupture, ooze, and form a yellowish-brown crust, not burrowing mites.
