Section 1: Community Assessment & Epidemiology (Questions
1-15)
Question 1 A community health nurse is conducting a windshield survey of a low-
income urban neighborhood. Which observation would be classified as a primary
data source for the community assessment?
A. Reviewing census tract data showing 32% of residents live below the poverty line
B. Observing three abandoned buildings with broken windows and overgrown lots
during the drive-through
C. Examining county health department records of childhood immunization rates
D. Analyzing CDC mortality statistics for the zip code over the past five years
B. Observing three abandoned buildings with broken windows and overgrown
lots during the drive-through [CORRECT]
Rationale: Primary data are collected directly by the nurse through observation,
interviews, or surveys. Observing physical conditions during a windshield survey
constitutes primary data collection. Census data, health department records, and
CDC statistics are all secondary data sources collected by other entities.
Correct Answer: B
Question 2 During a community health assessment, the nurse identifies that 45 new
cases of Type 2 diabetes were diagnosed in a population of 15,000 adults over the
past year. What is the incidence rate per 1,000 population?
,A. 1.5 per 1,000
B. 3.0 per 1,000
C. 4.5 per 1,000
D. 6.0 per 1,000
B. 3.0 per 1,000 [CORRECT]
Rationale: Incidence rate = (New cases / Population at risk) × multiplier. Calculation:
(,000) × 1,000 = 3.0 per 1,000. Option A incorrectly divides by 30,000. Option
C uses 45 directly without proper calculation. Option D doubles the correct rate.
Correct Answer: B
Question 3 A community health nurse is analyzing an outbreak of foodborne illness
at a church picnic. Of 120 attendees, 80 ate the potato salad and 45 of those became
ill. What is the attack rate among those who consumed the potato salad?
A. 37.5%
B. 45.0%
C. 56.3%
D. 75.0%
C. 56.3% [CORRECT]
Rationale: Attack rate = (Number ill / Number exposed) × 100. Calculation: ()
× 100 = 56.25%, rounded to 56.3%. Option A uses 45/120 (all attendees). Option B
reports the number ill without calculation. Option D uses 60/80 with incorrect
numerator.
Correct Answer: C
Question 4 The epidemiologic triangle consists of three interacting factors. Which
factor represents the "environment" component when analyzing a community
outbreak of West Nile virus?
,A. The Culex mosquito that transmits the virus
B. The human host who develops neuroinvasive disease
C. Standing water in abandoned swimming pools and storm drains
D. The viral pathogen itself
C. Standing water in abandoned swimming pools and storm drains [CORRECT]
Rationale: In the epidemiologic triangle, the environment includes external
conditions that support disease transmission. Standing water provides breeding
habitat for Culex mosquitoes, representing the environmental factor. The mosquito is
the vector (agent-related), the human is the host, and the virus is the agent.
Correct Answer: C
Question 5 A public health nurse is comparing secondary data sources for a
community assessment. Which source would provide the most current, localized
information about sexually transmitted infection rates?
A. National Health and Nutrition Examination Survey (NHANES)
B. State health department's electronic disease surveillance system
C. Healthy People 2030 national objectives database
D. World Health Organization (WHO) global health observatory
B. State health department's electronic disease surveillance system [CORRECT]
Rationale: State-level electronic surveillance systems provide real-time, locality-
specific disease data required for community-level interventions. NHANES provides
national representative data with lag time. Healthy People 2030 sets targets rather
than reporting current rates. WHO data is global and lacks local granularity.
Correct Answer: B
Question 6 During a community assessment, the nurse calculates that a rural county
has 850 existing cases of hypertension among 12,500 adults. What is the prevalence
proportion per 100 population?
, A. 5.8 per 100
B. 6.8 per 100
C. 7.8 per 100
D. 8.8 per 100
B. 6.8 per 100 [CORRECT]
Rationale: Prevalence proportion = (Existing cases / Total population) × 100.
Calculation: (,500) × 100 = 6.8%. Option A incorrectly uses 725/12,500.
Option C uses 975/12,500. Option D uses 1,100/12,500.
Correct Answer: B
Question 7 A community health nurse is using the Community Health Needs
Assessment (CHNA) framework. Which activity occurs during the "collecting and
analyzing data" phase?
A. Prioritizing identified health needs based on criteria and community input
B. Conducting key informant interviews with local clergy and school principals
C. Developing an action plan with measurable objectives and timelines
D. Implementing evidence-based interventions to address priority needs
B. Conducting key informant interviews with local clergy and school principals
[CORRECT]
Rationale: Key informant interviews are primary data collection methods used
during the data collection and analysis phase. Prioritizing needs occurs in the
"identifying and prioritizing needs" phase. Developing action plans follows
prioritization. Implementation occurs after planning is complete.
Correct Answer: B
Question 8 A nurse is calculating the crude mortality rate for a community of 85,000
residents. If 425 deaths occurred in the past year, what is the rate per 1,000
population?
