INFECTION CONTROL
TRAINING QUESTIONS
1. All of the following statements regarding hand hygiene in
healthcare settings are true EXCEPT which one?
A. Outbreaks of HBV and HCV infections, primarily in
medical settings outside of acute care hospitals, indicate a
failure of healthcare personnel (HCP) to perform hand
hygiene and wear gloves.
B. While the hand hygiene guideline applies to oral
healthcare settings, evidence suggests low compliance with
recommended hand hygiene practices by oral HCP.
C. Ongoing education and competency-based training are
critical for ensuring that infection prevention policies and
procedures are understood and followed.
,D. Hand hygiene-related competency following each training
cycle does not need to be documented. D. Hand hygiene-
related competency following each training cycle does not
need to be documented.
1. In healthcare settings pathogenic organisms can be
detected __________.
A. in air
B. in water
C. on fomites
D. All of the above. D. All of the above
1.All of the following statements are correct with respect to
sterilization and levels of disinfection except which one?
A. Sterilization is a validated process that destroys all forms
of microbial life.
B. High-level disinfection kills all pathogens but not all
bacterial spores.
C. Intermediate-level disinfection kills mycobacteria, all
nonlipid or small viruses (e.g., polio), all fungi, all vegetative
bacteria, and all lipid or medium-size viruses (e.g., HBV,
HIV), but not bacterial kill spores.
,D. Low-level disinfection kills some nonlipid or small viruses
(e.g., polio), some fungi, all vegetative bacteria, and all lipid
or medium-size viruses (e.g., HBV, HIV). C. Intermediate-
level disinfection kills mycobacteria, all nonlipid or small
viruses (e.g., polio), all fungi, all vegetative bacteria, and all
lipid or medium-size viruses (e.g., HBV, HIV), but not
bacterial kill spores.
10. All of the following are specifically designed point-of-use
devices to ensure water quality when performing oral
surgical procedures for the delivery of sterile irrigating fluid
EXCEPT which one?
A. Bulb syringe.
B. Single-use disposable products.
C. Air-water syringe.
D. Sterilizable tubing. C. Air-water syringe.
10. All of the following statements about antiseptic
handwash are correct EXCEPT which one?
A. Antiseptic handwash is defined as washing hands with a
soap containing an antiseptic agent and water.
, B. The FDA classifies povidone iodine (5 to 10%) as a
Category I antiseptic agent.
C. The use of antimicrobial-impregnated wipes (i.e.,
towelettes) is an acceptable alternative to antiseptic
handwash.
D. Antiseptic handwash with povidone iodine removes or
destroys transient microorganisms and reduces the resident
hand flora. C. The use of antimicrobial-impregnated
wipes (i.e., towelettes) is an acceptable alternative to
antiseptic handwash.
10. All of the following statements are correct with respect to
cleaning reusable instruments and other devices except
which one?
A. If visible debris (both organic and inorganic
contaminants) is not removed, it will interfere with microbial
inactivation and compromise the sterilization and
disinfection processes.
B. Factors to consider in selecting a cleaning method include
(1) efficacy of the method, process, and equipment used; (2)
compatibility with items to be cleaned; and (3) occupational
health and exposure risks.
C. The use of automated equipment (e.g., ultrasonic cleaner
or washer/disinfector) is discouraged because manual
cleaning of instruments is more efficient.
