INFECTION CONTROL CDC WITH
WELL EXPLAINED STUDY GUIDE
In the text the acronym DHCP is used - what does it reference? - correct
answer<<<<<<<💖💖💖✔refers to all paid and unpaid personnel in the dental health-care setting
who might be occupationally exposed to infectious materials
ie dentist, dental hygienest, dental assistant, front desk
How are pathogenic microorganisms like HBV transmitted in the dental setting? - 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 air- borne microorganisms
that can remain suspended in the air for long periods
What is the difference between universal precautions and standard precautions in the clinical dental
practice? - correct answer<<<<<<<💖💖💖✔Standard precautions apply to contact with 1) blood; 2)
all body fluids, secretions, and excretions (except sweat), regard- less 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.
In the text the acronym OPIM is used - what does it reference? - correct
answer<<<<<<<💖💖💖✔Other potentially infectious materials. OSHA term that refers to 1) body
fluids including semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial
fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures; any body fluid visibly contaminated
with blood; and all body fluids in situations where differentiating between body fluids is difficult or
impossible; 2) any unfixed tissue or organ (other than intact skin) from a human (living or dead); and 3)
HIV-containing cell or tissue cultures, organ cultures; HIV- or HBV-containing culture medium or other
solutions; and blood, organs, or other tissues from experimen- tal animals infected with HIV or HBV.
Can an individual that is a carrier of Hepatitis B work as a dental receptionist? Why or why not? - correct
answer<<<<<<<💖💖💖✔Yes, as that position does not perform exposure-prone procedures.
, Can an individual with Hepatitis C work as a dental hygienist?Why or why not? - correct
answer<<<<<<<💖💖💖✔No restrictions on professional activity.HCV-positive health-care personnel
should follow aseptic technique and standard precautions.
Given the scenario that you have chicken pox, when can you return to work as a dental hygienist? -
correct answer<<<<<<<💖💖💖✔From tenth day after first exposure through twenty-first day
(twenty-eighth day if varicella-zoster immune globulin [VZIG] administered) after last exposure.
How long is your dentist-employer required to keep your confidential medically related information? -
correct answer<<<<<<<💖💖💖✔at least the duration of employment plus 30 years
What body fluid contains the greatest proportion of HBV infectious particle titers and is the most critical
vehicle of transmission in the health-care setting? - correct answer<<<<<<<💖💖💖✔bloodand
blood-contaminated saliva
How long can HBV survive in dried blood at room temperature on an environmental surface? - correct
answer<<<<<<<💖💖💖✔less than or equal to 1 week
Given the scenario that you received the primary vaccine series for HBV, what should you do if you did
not develop an adequate antibody response? - correct answer<<<<<<<💖💖💖✔complete a second
3-dose vaccine series or be evaluated to determine if they are HBsAg-positive. If no antibody response
occurs after the second series, testing for HBsAg should be performed
Given the scenario that you received the primary vaccine series for HBV, what should you do if you are a
nonresponder to the vaccination? - correct answer<<<<<<<💖💖💖✔Nonresponders to vaccination
who are HBsAg-negative should be considered susceptible to HBV infection and should be counseled
regard- ing precautions to prevent HBV infection and the need to obtain HBIG prophylaxis for any known
or probable parenteral exposure to HBsAg-positive blood.
Given the scenario that you received the primary vaccine series for HBV and you responded accordingly
with antibodies, how often should you receive a booster does of the vaccine? - correct
answer<<<<<<<💖💖💖✔Vaccine-induced antibodies decline gradually over time, and 60% of
persons who initially respond to vaccination will lose detectable antibodies over 12 years. Even so,
immunity continues to prevent clinical disease or detectable viral infection. Booster doses of vaccine
