scalp. Which level of infection control is required for the tools that will come into direct
contact with the client's blood?
A. Sanitation
B. Disinfection
C. Sterilization
D. Decontamination
Correct Answer: C
Explanation: Sterilization destroys all microbial life, including bacteria, viruses, fungi, and

does not eliminate all pathogens.

Correct Answer: B
Explanation: The Environmental Protection Agency (EPA) registers and regulates

B. Proceed with the service using gloves.
C. Soak the finger in warm water and continue.
D. Refer the client to a physician and decline service.

client?
A. Metal nail file
