What do Incidence Calculations measure? - correct answerThe number of people at risk
for infection.
What does Prevalence of an infection measure? - correct answerhow the disease might
effect the entire population of a given area.
How do you calculate the incidence rate of an infection? - correct answerBy dividing the
number of new cases of a disease found in a specific time interval by the number of
people at risk of being infected. ** It is important to remember that the number of new
cases should only be divided by the number of people who are capable of contracting
the disease to get an accurate measurement of only those at risk.**
How is the Standardized Infection Ratio calculated? - correct answerBy dividing the
number of observed infections by the number of predicted infections. **Ex: 15 known
infections with 10 predicted infections 15/10=1.5 infection ratio.**
What does generating surveillance data require? - correct answerUsing all available
resources to gather as much patient data as possible on a specified population,
including those who have been infected, those likely to be infected, and those predicted
to be infected.
What is the mean value and how do you calculate it? - correct answerThe mean value is
the average data point, and is calculated by adding all values together and then dividing
by the number of values present. **Ex: 32, 33, 38, 42, 43, 37; add all of these numbers
together and divide by 6 = mean of 37.5**
What is the median value? - correct answerThe middle value in a set of collected
numbers.
What is the mode value? - correct answerThe most commonly collected numerical
point.
Define High Standard Deviation. - correct answerData is widely spread out and far from
the mean.
Define Standard Deviation/Low Variance. - correct answerData is similar and closer to
average.
Who tracks foodborne and other enteric bacteria's resistance to antimicrobial therapy? -
correct answerThe National Antimicrobial Resistance Monitoring System for Enteric
Bacteria (NARMS)
, What defines an Outbreak? - correct answerWhen there is a sudden increase of
infectious disease cases over a relatively short amount of time, often originating from a
specific area.
Why is it important to take organism incubation periods into consideration? - correct
answerThese periods will determine the amount of symptom monitoring required.
When are outbreaks communicated to the public? - correct answerWhen they have the
potential to cause substantial harm?
What is the infection tracking system that provides data to healthcare facilities to aid in
prevention efforts and elimination of Healthcare-Associated Infections (HAI)? - correct
answerThe National Healthcare Safety Network (NHSN).
Why is Active Surveillance Culture (ASC) testing performed? - correct answerto identify
the presence of microorganisms in a patient to determine if isolation precautions need
to be implemented or discontinued. **Ex: MRSA nasal swabs on all patients admitted to
Med-Surg Units.**
What have scientific studies identified as the most common mode of pathogen
transmission? - correct answerHands.
What is a proven method of preventing infection and disease? - correct answerProper
hand hygiene.
PPE are selected based on what 3 factors? - correct answer1. the type of exposure
2. appropriateness for task
3. proper fit
Proper PPE Donning Order: - correct answer1. Gown
2. Mask/Respirator
3. Goggles/Faceshield
4. Gloves
Proper PPE Doffing Order: - correct answer1. Gloves
2. Goggles/Faceshield
3. Gown
4. Mask/Respirator (Outside of room with door closed).
How are respiratory illnesses primarily transported? - correct answerVia airborne
droplets from coughing or sneezing.
Which route of medication delivery offers direct access to the bloodstream?
How must these medications be prepared? - correct answerParenteral (IV) route.
Sterile technique
