Which of the following is the FIRST step in responding to a blood exposure incident?

In responding to a blood exposure incident, stopping the service is the first critical step. This action is crucial because it ensures the immediate safety of both the client and the provider, preventing further exposure to blood or bodily fluids during the service. Continuing the service could exacerbate the situation, increasing the risk of contamination or infection.

Once the service is stopped, other important steps follow, such as notifying the supervisor, washing hands thoroughly, and applying antiseptic. Each of these actions is vital for proper protocol and hygiene, but prioritizing the halt of the service fundamentally preserves safety and allows for a structured response to the incident. Addressing the situation promptly mitigates further risk and sets the stage for the necessary clean-up and follow-up procedures.
