1. I was discovered in 1894 by a Swiss physician in Hong Kong
2. I was the causative agent of an epidemic that tore through Europe in the 1300s,
killing millions of people
3. I am a rod shaped Gram-negative, facultative anaerobic bacterium
4. People most commonly become infected when bitten by an infected flea; however
can also become infected from direct contact with infected fluids or tissues from an
animal that is sick or has died from the disease.
5. Three types: Bubonic, septicemic, and pneumonic
6. Symptoms of me may vary based on form. Bubonic form presents with swollen,
tender and painful lymph nodes.
7. A person usually becomes ill with the bubonic form 2-6 days after being infected.
Airborne route is 1-3 days.
8. There are still sporadic cases in the US - ANS-Yersinia pestis (Plague)
A 21-year-old college student presents to the ED with a high fever. Blood, urine, and
CSF cultures are ordered, as well as acetaminophen and dexamethasone. The patient
is admitted, administered IV ceftriaxone, and placed on precautions. The next day the
cultures of both the blood and the CSF were reported to be growing meningococci.
Which of the following is correct?
(A) Droplet precautions may be discontinued 24 hours after fever resolves
(B) Droplet precautions may be discontinued 24 hours after IV ceftriaxone is started
(C) Airborne precautions may be discontinued 24 hours after fever resolves.
(D) Airborne precautions may be discontinued 24 hours after IV ceftriaxone is started -
ANS-B
A 38-year-old female is undergoing abdominal surgery. A foul-smelling abscess is
encountered and a Gram stain of the abscess material reveals gram-negative rods. No
growth is reported from aerobic microbiologic cultures. Which of the following organisms
is MOST likely involved?
A) Staphylococcus epidermidis
B) Bacteroides fragilis
C) Escherichia coli
D) Bacillus subtilis - ANS-B
, Bacteroides fragilis is an obligately anaerobic, Gram-negative, rod-shaped bacterium. It
is part of the normal microbiota of the human colon and is generally commensal, but
can cause infection if displaced into the bloodstream or
A dead bat was found in a family home. Public Health post-exposure management
should include
(A) recommending the bat's brain be examined for Negri bodies.
(B) reporting the dead bat to domestic animal control.
(C) observing the family's activities for 30 days.
(D) alerting the neighborhood of potential risks of being bitten by a ba - ANS-A
A laboratory report indicates that beta-lactamase positive, coagulase-negative
staphylococci is present in a surgical wound. These results show that the organism
(A) is Gram-negative.
(B) ferments lactose.
(C) is beta-hemolytic.
(D) is penicillin-resistant. - ANS-D
A laboratory reported a coagulase-positive staphylococci from a central line tip culture
which had an MIC of 8 ug/ML to oxacillin. This isolate would be identified as
A) methicillin-resistant S. aureus.
B) methicillin-sensitive S. aureus.
C) methicillin-resistant S. epidermidis.
D) methicillin-sensitive S. epidermidis. - ANS-A
A new infection preventionist (IP) is preparing a report and wants to describe the data.
The simplest and crudest levels of measurements should include which of the
following?
A) rates
B) risk ratios
C) nominal scales
D) measures of association - ANS-The correct answer is C: nominal scales
A nursing student who had an MMR vaccination in 1980 as a child has
laboratory-confirmed mumps. Which of the following is the most likely explanation?
A) The vaccine batch was defective.
B) This is a false positive laboratory result.
C) A killed vaccine is not as effective.
D) A second dose of the vaccine was not given. - ANS-D
