NC Infection Control UPDATED ACTUAL
Exam Questions and CORRECT Answers
CDC - CORRECT ANSWER -
Pathogenic microorganisms are transmitted in the dental setting through: - CORRECT
ANSWER -1) direct contact with blood, oral fluids, or other patient materials;
2) indirect contact with contaminated objects (e.g., instruments, equipment, or environmental
surfaces);
3) contact of conjunctival, nasal, or oral mucosa with droplets (e.g., spatter) containing
microorganisms generated from an infected person and propelled a short distance (e.g., by
coughing, sneezing, or talking); and
4) inhalation of airborne microorganisms that can remain suspended in the air for long periods.
Infection through any of these routes requires that all of the following conditions be present: -
CORRECT ANSWER -1. a pathogenic organism of sufficient virulence and in adequate
numbers to cause disease;
2. a reservoir or source that allows the pathogen to survive and multiply (e.g., blood);
3. a mode of transmission from the source to the host;
4. a portal of entry through which the pathogen can enter the host; and
5. a susceptible host (i.e., one who is not immune).
Preventive practices used to reduce blood exposures, particularly percutaneous exposures,
include: - CORRECT ANSWER -1) careful handling of sharp instruments,
2) use of rubber dams to minimize blood spattering;
3) handwashing; and
4) use of protective barriers (e.g., gloves, masks, protective eyewear, and gowns).
Standard precautions apply to contact with - CORRECT ANSWER -1) blood;
2) all body fluids, secretions, and excretions (except sweat), regardless of whether they contain
blood;
, 3) nonintact skin; and
4) mucous membranes.
Saliva has always been considered a potentially infectious material in dental infection control;
thus, no operational difference exists in clinical dental practice between universal precautions
and standard precautions.
to prevent potential spread of certain diseases (e.g., TB, influenza, and varicella) that are
transmitted through airborne, droplet, or contact transmission - CORRECT ANSWER -
precations include:
patient placement (e.g., isolation), adequate room ventilation, respiratory protection (e.g., N-95
masks) for DHCP, or postponement of nonemergency dental procedures.
primary strategy for protecting against bloodborne pathogens: - CORRECT ANSWER -
engineering controls that eliminate or isolate the hazard (e.g., puncture-resistant sharps
containers or needle-retraction devices)
Where engineering controls are not available or appropriate, work-practice controls that result in
safer behaviors (e.g., one-hand needle recapping or not using fingers for cheek retraction while
using sharp instruments or suturing), and use of personal protective equipment (PPE) (e.g.,
protective eyewear, gloves, and mask) can prevent exposure
The effectiveness of the infection-control program should be evaluated on a - CORRECT
ANSWER -day-to-day basis and over time to help ensure that policies, procedures, and
practices are useful, efficient, and successful
Alcohol-based hand rub: - CORRECT ANSWER -An alcohol-containing preparation
designed for reducing the number of viable microorganisms on the hands
Antimicrobial soap - CORRECT ANSWER -A detergent containing an antiseptic agent
