, Question 1
A community health nurse is analyzing mortality data for a county and finds
that the crude mortality rate is 12 per 1,000, while the age-adjusted mortality
rate is 8 per 1,000. Which conclusion best interprets this discrepancy?
A. The county has a higher proportion of older adults, inflating the crude
rate.
B. The county has a higher proportion of younger adults, inflating the
crude rate.
C. The age-adjusted rate is inaccurate because it does not account for
race.
D. The crude rate is the preferred measure for comparing counties.
Correct Answer: A - The county has a higher proportion of older
adults, inflating the crude rate.
RATIONALE
A crude rate higher than the age-adjusted rate suggests the population
is older than the standard population, inflating mortality.
Age-adjustment removes the effect of age distribution, enabling valid
comparisons. The other options misstate the relationship or the
purpose of adjustment.
Question 2
A public health nurse is planning a program to reduce obesity in a low-income
urban neighborhood. Which intervention best reflects the socio-ecological
model's emphasis on policy and environmental change?
A. Providing free gym memberships to individuals with BMI >30.
B. Offering weekly nutrition education classes at the community center.
C. Advocating for zoning laws that limit fast-food outlets near schools.
D. Distributing pamphlets on healthy cooking to households.
Correct Answer: C - Advocating for zoning laws that limit
fast-food outlets near schools.

, RATIONALE
The socio-ecological model's outermost level targets policy and
environmental changes that affect entire populations. Zoning laws are
a policy-level intervention, whereas individual memberships,
education, and pamphlets target intrapersonal or interpersonal levels.
Thus, C is the best example of macro-level change.
Question 3
A nurse is investigating a cluster of Legionnaires' disease cases in a
community. Which epidemiologic measure is most appropriate to identify the
source of exposure?
A. Calculate the attack rate among exposed vs. unexposed groups.
B. Determine the case fatality rate.
C. Calculate the age-adjusted mortality rate.
D. Measure the prevalence of chronic lung disease.
Correct Answer: A - Calculate the attack rate among exposed vs.
unexposed groups.
RATIONALE
Attack rate is the proportion of exposed persons who become ill, and
comparing exposed vs. unexposed groups helps identify the source.
Case fatality and mortality rates describe severity, not exposure
source. Prevalence of chronic disease is not directly linked to outbreak
source identification.
Question 4
A community health nurse is reviewing a new policy that mandates reporting
of all COVID-19 positive test results to the local health department. Which
ethical principle is most directly upheld by this mandate?
A. Autonomy
B. Beneficence
C. Justice
Page 3
, D. Nonmaleficence
Correct Answer: B - Beneficence
RATIONALE
Mandatory reporting serves the public good by enabling contact
tracing and outbreak control, reflecting beneficence (doing good for
the community). Autonomy concerns individual choice, justice
concerns fair distribution, and nonmaleficence concerns avoiding
harm. The primary principle here is beneficence.
Question 5
A nurse is conducting a community assessment using the windshield survey
method. Which data would be most appropriately collected through this
method?
A. Immunization rates from the health department.
B. Number of grocery stores and their locations.
C. Self-reported health status from a random sample.
D. Hospital discharge diagnoses for the past year.
Correct Answer: B - Number of grocery stores and their
locations.
RATIONALE
Windshield surveys involve direct observation of the community's
physical environment, such as housing, businesses, and infrastructure.
Immunization rates, self-reported health status, and discharge
diagnoses are obtained from secondary data sources or surveys, not
observation. Thus, B is correct.
Question 6
A nurse is evaluating the effectiveness of a community-based hypertension
screening program. Which outcome measure best reflects the program's impact
on secondary prevention?
