ANSWERS WITH RATIONALES LATEST UPDATE OF THIS
YEAR.ASSURED PASS
SECTION 1: INFECTION CONTROL AND SAFETY (Questions 1-25)
1. What is the term for one-celled microorganisms that have both plant and
animal characteristics?
A. Viruses
B. Fungi
C. Bacteria
D. Parasites
Correct Answer: C. Bacteria
Rationale: Bacteria are single-celled microorganisms that exhibit both plant and
animal characteristics. They are classified by their shape and can be either
pathogenic (harmful) or nonpathogenic (harmless). Unlike viruses, bacteria can
reproduce independently and are susceptible to certain disinfectants and
antibiotics.

,2. What type of bacteria are short, rod-shaped organisms that produce diseases
such as tetanus and tuberculosis?
A. Cocci
B. Spirilla
C. Bacilli
D. Staphylococci
Correct Answer: C. Bacilli
Rationale: Bacilli are rod-shaped bacteria that are the most common type. They
are responsible for several serious diseases including tetanus (lockjaw), typhoid
fever, tuberculosis, and diphtheria. Their rod-like shape distinguishes them from
spherical cocci and spiral-shaped spirilla.

3. What is the term for disease-causing microorganisms?
A. Nonpathogenic
B. Saprophytes
C. Pathogenic
D. Beneficial bacteria
Correct Answer: C. Pathogenic
Rationale: Pathogenic microorganisms are those that cause disease in their host.
They invade the body and disrupt normal physiological functions. Nonpathogenic
,bacteria are harmless and often beneficial. The distinction between pathogenic
and nonpathogenic organisms is fundamental to infection control practices in
esthetics.

4. What is the highest level of decontamination that destroys all microorganisms
including spores?
A. Sanitization
B. Disinfection
C. Sterilization
D. Antisepsis
Correct Answer: C. Sterilization
Rationale: Sterilization is the complete destruction of all microorganisms,
including bacterial spores. This is the highest level of decontamination and is
achieved through autoclaving (steam under pressure) or dry heat. Disinfection
eliminates most pathogens but not spores, while sanitization simply reduces the
number of microorganisms on a surface.

5. What type of disinfectant is used to destroy bacteria on the skin?
A. Sanitizer
B. Disinfectant
, C. Antiseptic
D. Sterilizer
Correct Answer: C. Antiseptic
Rationale: Antiseptics are chemical agents applied to living tissue to inhibit or
destroy microorganisms. They are milder than disinfectants and can be used safely
on skin. Disinfectants are stronger and used only on inanimate objects or surfaces.
Sanitizers simply reduce the number of pathogens without necessarily eliminating
them entirely.

6. A client with an open wound should NOT receive which service?
A. Manicure
B. Pedicure
C. Facial treatment
D. Makeup application
Correct Answer: C. Facial treatment
Rationale: An esthetician should never perform a facial treatment on a client with
open wounds, abrasions, or broken skin due to the risk of infection. The skin
barrier is compromised, and products or bacteria could enter the bloodstream.
The client should be referred to a medical professional for treatment.
