SECTION 1: INFECTION CONTROL, SANITATION, AND SAFETY
(Questions 1–30)
---
Question 1
Which of the following is the MOST effective method for preventing cross-
contamination during a cosmetology service?
A) Wearing disposable gloves during the entire service
B) Washing and sanitizing hands before the service only
C) Using the same implements on multiple clients after wiping with a dry cloth
D) Applying styling products to the client's hair before washing hands
Correct Answer: A
Rationale: Wearing disposable gloves during the entire service creates a barrier
between the practitioner's hands and the client, significantly reducing the risk of
cross-contamination. Hand washing alone is insufficient once the service begins, as
,hands can become contaminated through contact with products, hair, and skin.
Using implements without proper disinfection or failing to wash hands before
service violates basic infection control protocols.

Question 2
What procedure MUST be performed immediately after a reusable implement has
been used on a client and before it is disinfected?
A) Store it in a closed container
B) Rinse it with warm water
C) Clean it with soap and water to remove all visible debris
D) Spray it with a disinfectant
Correct Answer: C
Rationale: Cleaning with soap and water to remove all visible debris must occur
before disinfection because organic matter (hair, skin cells, blood) can inactivate
many disinfectants. Disinfection cannot be effective if the implement is not first
thoroughly cleaned. Storing without cleaning or simply spraying with disinfectant
does not adequately remove bioburden.

Question 3
An autoclave operates at which temperature range to achieve sterilization?
,A) 100–110°C
B) 121–134°C
C) 150–170°C
D) 190–300°C
Correct Answer: B
Rationale: An autoclave uses steam under pressure to achieve sterilization at
temperatures between 121–134°C. This temperature range is sufficient to kill all
microorganisms, including bacterial spores. Lower temperatures are inadequate for
sterilization, while higher temperatures may damage instruments.

Question 4
Which of the following is a PRIMARY difference between sanitization and
sterilization?
A) Sanitization requires higher temperatures than sterilization
B) Sterilization destroys all microorganisms including spores; sanitization reduces
the number of pathogens
C) Sanitization is more effective than sterilization
D) There is no significant difference between the two processes
Correct Answer: B
, Rationale: Sterilization is the complete destruction of all microorganisms,
including bacterial spores, while sanitization (disinfection) reduces the number of
pathogens to a safe level but does not necessarily eliminate all spores. Sterilization
is the highest level of infection control and is required for implements that may
penetrate the skin.

Question 5
When performing a chemical service, what is the CORRECT order of draping
procedures?
A) Neck strip, cape, towel
B) Towel, neck strip, cape
C) Cape, towel, neck strip
D) Neck strip, towel, cape
Correct Answer: D
Rationale: The correct order for draping is: (1) neck strip (placed around the neck
to protect the skin), (2) towel (placed over the shoulders for additional protection),
and (3) cape (placed over the towel to protect the client's clothing). This layered
approach ensures maximum protection from chemicals and water.
