A 911 emergency operation center is flooded with calls at certain times of the day. What is the
distribution that is most often used to assess this data?
1) Normal
2) Binomial
3) Hypergeometric
4) Poisson - ✔✔✔-4) Poisson
The Poisson distribution is used to model data that represent the number of occurrences of a
specific event in a fixed period of time.
A consecutive series of 1,000 women newly identified with breast cancer included 235 who
currently smoked cigarettes. From this information one can correctly conclude that in this series
of woman...
1) Smoking cigarettes increases the incidence of breast cancer by 23.5%
2) Smoking cigarettes increases the prevalence of breast cancer by 23.5%
3) The incidence of smoking cigarettes at cancer diagnosis was 23.5%
4) The prevalence of smoking cigarettes at cancer diagnosis was 23.5% - ✔✔✔-4) The
prevalence of smoking cigarettes at cancer diagnosis was 23.5%
This is cross sectional sampling of women w/ breast cancer, so we can estimate prevalence.
Incidence cannot be estimated from cross-sectional data.
To estimate risk we would need to follow the same group of women over time.

A distinctive foundation of the Comprehensive Unit-based Safety Program (CUSP) developed at
Johns Hopkins and promoted by the Agency for Healthcare Research and Quality creates a
culture of safety by focusing on:
1) detecting and reporting sentinel events
2) open attitudes and mutual respect
3) using standardized checklists
4) assuring professional expertise - ✔✔✔-2) open attitudes and mutual respect
CUSP tools support change at the unit level to create a culture of safety. This is more
fundamental than checklists alone, although empowering all staff to participate in use of
checklists also has been part of CUSP's success in reducing the incidence of preventable adverse
patient outcomes. Studies have found that working in an environment where open and mutual
communication is present enhances clinical proficiency and job satisfaction.

Sentinel events are events so egregious that a single occurrence is prima facie evidence of
medical error (e.g. wrong-site surgery); however, few such events have proven to be reliable
indicators because many low-probability adverse outcomes are not entirely preventable despite
all aspects of care being correctly done.
A district health department is trying to decide whether to invest in interpretation services and
translated materials to address local language barriers, address needs of limited English
proficient (LEP) clients and meet Federal requirements.

recommendations for providing translated materials and interpretation services-is part of a...

2) Language Needs Assessment
3) Health Resource Access Assessment
4) Community Literacy Assessment - ✔✔✔-Language Needs Assessment includes a review of
four factors: The Four Factor Analysis - to guide LHDs (recipients) in meeting these mandates
and to provide recommendations for providing translated materials and interpretation services.
The four factors are:
1. The Number of proportion of LEP residents within each district,
2. The frequency with which LEP individuals come into contact w/ VDH programs
3. The nature and importance of the program, activity or service provided by the recipient to its
beneficiaries, and,
4. The resources available to the grantee/recipient and the costs of interpretation/translation
services

A health behavior survey conducted in a large urban area includes a question about whether a
person is a smoker. The company conducting the survey decides to increase the size of its

random sample of survey participants from 1,5000 people to approx. 20,000 people. This
change will most likely have which of the following effects?
A) Decreasing the variability of the estimate
B) Increasing the standard error of the estimate
C) No effect on survey stats because the population size is the same
D) Increase the CI width for the parameter - ✔✔✔-A) Decreasing the variability of the estimate
As sample size increases, the range decreases, which means variability decreases.
A local public health department (LHD) must make significant budget cuts. Area managers are
directed to review and compare current services, service utilization and cost to areas of need
identified a recent community health needs assessment completed by the LHD. This approach,
as a prelude to decision-making, is based on:
1) internal assessment and strategic goals
2) external assessment and department policy review
3) internal assessment and external assessment
4) strategic planning and maximizing program efficiency - ✔✔✔-3) Internal assessment and
external assessment
"In the context of public health assessment is the beginning of the continuum of problem
identification, priority setting, strategic planning, intervention and evaluation. Assessment can
be either internal, addressing processes within an organization, or external, addressing
processes within the community."
The decision is being made by the local health department (internal) after they evaluate their
budget. They are asking area managers to review and compare the LHD's community needs
assessment (external).
