10. Cultural Competence and Diverse Populations
1. A community health nurse is investigating a cluster of foodborne illnesses in a local residential
facility. To determine the source and transmission pattern, the nurse calculates the attack rate.
Which action best reflects the application of this epidemiological metric?
A. Identifying the total number of people who attended the event where the food was served.
, B. Calculating the number of ill persons divided by the total number of persons exposed to
the suspect food.
C. Measuring the total population of the facility to determine the prevalence of the pathogen.
D. Comparing the morbidity rate of the facility against the regional mortality rate for the
pathogen.
CORRECT ANSWER : B
Rationale: The attack rate is a specific form of incidence used during an outbreak to determine
the proportion of exposed individuals who become ill. Option B correctly identifies the formula
for the attack rate. Option A is incomplete, Option C refers to period prevalence, and Option D
refers to descriptive statistics that do not measure transmission risk.
2. A public health nurse is conducting an assessment of a community with a high incidence of lead
poisoning in children. Which environmental health initiative represents the most effective
primary prevention strategy?
A. Screening children for elevated blood lead levels during annual physical examinations.
B. Implementing a community-wide educational program on identifying and abating lead-
based paint hazards.
C. Providing nutritional counseling to families to increase calcium and iron intake to inhibit lead
absorption.
D. Monitoring local water supply pipes for lead leaching and issuing boil water advisories.
CORRECT ANSWER : B
Rationale: Primary prevention aims to prevent disease or injury before it occurs. Educating the
community on how to identify and remove lead hazards prevents exposure entirely. Option A is
secondary prevention (screening), Option C is tertiary prevention (minimizing harm from
established exposure), and Option D is a reactive measure for existing infrastructure.
3. A nurse is working with a vulnerable population of migrant farmworkers. Which action best
demonstrates the nurse’s role as an advocate in addressing systemic barriers to healthcare?
A. Providing free screenings at the worksite during lunch breaks.
B. Translating health education materials into the primary language of the farmworkers.
C. Collaborating with local legislators to propose mobile clinic funding for underserved
rural regions.
, D. Coordinating transportation services to help individuals attend their scheduled clinic
appointments.
CORRECT ANSWER : C
Rationale: Advocacy involves promoting changes in policies and systems to improve health
outcomes for a population. Option C targets the structural issue of access. Options A, B, and D
are important clinical or support interventions but address symptoms of inequity rather than
systemic barriers.
4. During a disaster response, the nurse is utilizing the START (Simple Triage and Rapid
Treatment) method for victims of a building collapse. A victim is found who is not breathing;
after the nurse clears the airway, the victim still does not breathe. What is the appropriate triage
tag?
A. Red (Immediate)
B. Yellow (Delayed)
C. Green (Minor)
D. Black (Expectant/Deceased)
CORRECT ANSWER : D
Rationale: According to the START triage protocol, if a victim is not breathing and remains
apneic after the airway is cleared, they are classified as deceased or expectant. Options A, B,
and C are incorrect because they require the patient to have signs of life and specific injury
severity levels.
5. A community health nurse is evaluating the effectiveness of a smoking cessation program.
Which outcome measurement indicates the best success for the program at the community level?
A. Number of participants who completed the 8-week support group series.
B. Self-reported reduction in cigarette consumption among the participants.
C. A 15% decrease in the smoking prevalence rate within the target community over two
years.
D. Number of promotional flyers distributed to local community centers.
CORRECT ANSWER : C
Rationale: Program evaluation at the community level focuses on population-based health status
changes. A decrease in prevalence reflects a measurable, long-term impact on community
, health. Options A, B, and D are process or short-term behavioral indicators that do not fully
capture community-level impact.
6. A nurse is planning a health promotion campaign for a community with a high prevalence of
type 2 diabetes. Which theoretical model is most appropriate for assessing the community's
readiness to change their dietary habits?
A. Health Belief Model
B. Epidemiological Triangle
C. Social Determinants of Health Framework
D. Milio’s Framework
CORRECT ANSWER : A
Rationale: The Health Belief Model focuses on individual perceptions of susceptibility, severity,
benefits, and barriers, which is essential for understanding readiness to change behavior. Option
B is for analyzing disease transmission, Option C is an assessment framework, and Option D
focuses on policy-level resource allocation.
7. A nurse identifies a rise in sexually transmitted infections (STIs) among the adolescent
population in the school district. Which strategy demonstrates the nurse practicing at the
population level?
A. Providing confidential STI testing to individual students in the nurse's office.
B. Partnering with the school board to mandate comprehensive sex education across the
district curriculum.
C. Calling the parents of students who test positive to ensure they seek medical treatment.
D. Referring individual students to the local health department for contact tracing.
CORRECT ANSWER : B
Rationale: Population-focused nursing targets the entire group to improve health outcomes
rather than just individuals. Mandatory education impacts the knowledge and behavior of the
entire student body. Options A, C, and D are focused on individual clinical care.
8. When conducting a community assessment, the nurse utilizes "Windshield Survey" data. What is
the primary purpose of this tool?
A. To gather statistical health data from local hospitals.
