CBIC Exam Secrets Study Guide
QuestionsA
A broad-spectrum antibiotic is usually administered for empirical therapy because -
ANS-the pathogenic organism is not yet identified.
A group of staff on the hospital unit cooperated to develop a plan to implement
preventive strategies, resulting in a 50% decline in SSI with subsequent adoption of
these strategies by other units. This is an example of... - ANS-positive deviance
A nurse has added both piperacillin/tazobactam and an aminoglycoside to the same IV
infusion. This practice... - ANS-inactivates both agents
A nurse who reports for work with a fever and cough, obviously ill, should be... -
ANS-excluded from work
A pregnant healthcare worker should be routinely screened for what condition? -
ANS-HIV
A woman admitted for an elective Caesarean had some bleeding after surgery and 30
hours post-op developed a high fever of unknown origin and died within 6 hours. This
case would primarily be classified as... - ANS-Sentinel event...because it was
unanticipated and resulted in death.
According to Hill's criteria for causation, when a number of studies over extended
periods of time show the same association even through different research methods are
used, this an example of... - ANS-consistency
According to the National Quality Forum's Endorsed Set of Safety Practices, Safe
Practice 23, Care of the Ventilated Patient, which actions should be taken to prevent
complications? - ANS-Ventilation-associated pneumonia, Dental complications, Venous
thromboembolism, and Peptic ulcer disease.
According to the second IOM report, Crossing the Quality Chasm: A New Health
System for the 21st Century, the primary aim of the healthcare system should be on... -
ANS-patient safety
, An increase in the number of positive microbiological cultures in the absence of clinical
disease is classified as a(n)... - ANS-pseudo-outbreak
Dietary restrictions that are recommended by the CDC, HHS, and USDA for neutropenic
patients to prevent infection include which measures? - ANS-Avoid raw raspberries and
strawberries
Use only pasteurized dairy products
Reheat deli meats to steaming hot before eating
If 10 CLABSI infections occurred out of 3840 CL days, and the expected number of
infections is 7.5, the SIR is... - ANS-1.3... The formula for calculating SIR: Number of
infections / Number of expected infections...10/7.5=1.3
If power is interrupted to the operating rooms during construction, what precaution is
necessary prior to putting the HVAC system bac into service? - ANS-Running the HVAC
system for a period of time to flush the ducts.
If the length of stay of 10 patients in days were 1, 29, 4, 3, 2, 4, 1, 3, 1, and 2, which
measure of central tendency provides the most useful information about lengths of
stay? - ANS-Median...these data contain an outlier (29 days), which skews the average
to 5, so mean is not useful. The mode is 1 because that number occurs three time, but
this provides almost no information about the range of lengths of stay. The median is
calculated by reordering the data into rank order: 1, 1, 1, 2, 2, 3, 3, 4, 4, 29. Because
there is an even number, the two central number, 2 and 3, are averaged, with the result
of 2.5, which provides the most useful information about the lengths of stay.
Immunocompromised patients at risk of Pneumocystis jiroveci infection, such as
patients with HIV/AIDS, should receive antibiotic prophylaxis with... - ANS-vancomycin
In a 30-day period in the ED, there were 28 cases of influenza diagnosed: 12 were
female and 16 were male. What is the ratio of female to male cases? - ANS-3:4
In a community outbreak of gonorrhea, out of the initial 40 cases identified, the ratio of
female to male cases was 3:5. If 120 cases are projected and the same ratio persists,
how many additional cases will be female? - ANS-30 additional female cases. Rational:
40=3x+5x --> 40 = 8x --> x = 5 --> = 5(3:5) --> 40 = 15:25 --> 120-40 = 80 --> 40*2 =80
so...= 2(15:25) --> 30 additional female cases
In a normal distribution curve, what percentage of results should be within the first
standard deviation above and below the mean? - ANS-68%
