Blood exposure in the salon

A nick during a service is common, and the exam expects a fixed sequence rather than improvisation. It also expects you to know why the sequence exists, which is a single idea applied without exception.

Standard precautions	Treat every client's blood as potentially infectious
Why	Infection status is often unknown, including to the client
The virus that drives salon rules	Hepatitis B — it survives on surfaces for an extended period
A nick during a service	Stop, glove, control the bleeding, disinfect the implement
A contaminated surface	A disinfectant registered as effective against HIV and hepatitis B
Cotton contaminated with blood	Sealed in a marked bag, disposed of per local requirements
A used razor blade	Into a puncture-resistant sharps container

Where the point is lost: Gloves go on before contact, not after, which is why "stop" comes first in the sequence — the pause is what makes gloving possible. And alcohol hand sanitizer is not adequate after contact with blood or body fluids: that is one of the two situations where washing with soap and running water is required rather than merely preferred.
