CBIC CIC Practice Exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
- Medical intervention factors that affect risk of infection - CORRECT
ANSWERS indwelling devices, staffing ratio, lengths of stay,
duration of invasive procedures, medications, # of exams by
providers, type of institution, and knowledge/experience of providers
environmental intervention factors that affect risk of infection -
CORRECT ANSWERS disinfectant type used, contact with
animals, hand hygiene
anatomical/phys factors that affect risk of infection - CORRECT
ANSWERS preexisting diseases, trauma, malignancies, age,
gender, and nutritional status
DMAIC - CORRECT ANSWERS D=define customers, project
boundaries, and processes
M=measure performance
A=analyze data to identify causes of variation, gaps in performance,
and prioritize actions
I=improve the process
C=control the process to prevent reverting
What should an effective surveillance program be able to provide? -
CORRECT ANSWERS Detection of infections and injuries,
identify trends, identify risk factors associated with infections and
other AEs detect outbreaks and clusters, assess the overall
effectiveness of the infection control and prevention program and
,demonstrate changes in proactive and processes that lead to better
outcomes
Define point prevalence - CORRECT ANSWERS number of
persons ill on the date divided by the population on that date.
Define attack rate - CORRECT ANSWERS Number of people
at risk in whom a certain illness develops / (divided by) / Total
number of people at risk
Define prevalence - CORRECT ANSWERS fraction of a
population having a specific disease at a given time
Define incidence - CORRECT ANSWERS number of new
cases of a disease divided by the number of persons at risk for the
disease.
Type of specimen for C. diff - CORRECT ANSWERS liquid
stool is required
When to suspect C. diff infection? - CORRECT ANSWERS
when 3 or more unformed/watery stool in 24 hrs occurs
Relative Risk (RR) - CORRECT ANSWERS Used in cohort
studies to determine how strongly a risk factor is associated with an
outcome.
, 1 is the null= no significance of the association between exposure and
adverse event
P(X infection or exposed)/P(Y infection or unexposed) = RR
Details of control chart - CORRECT ANSWERS central line =
the ave of data pts
x axis = time
y axis = rate/count
may be upper control/lower control limit lines and +/- 3 SD lines
Directly observed therapy (DOT) - CORRECT ANSWERS
requires that a health care provider directly observe the patient
swallowing the pills, whether it is in the hospital, office, or home care
setting
the best method for TB regimen, intermittent therapy, MDRO, high
risk for noncompliance (drug abusers/homeless)
Hill's Criteria of Causality - CORRECT ANSWERS 1)
strength of association- relationship between casual factor and disease
outcome
2) consistency of finding- associations are repeated
3) specificity of association- very specific cause
4) temporality- cause must be before the effect
5) biological gradient- dose and response relationship, more exposure
causes higher risk
