Community Health Foundations, Epidemiology & Population Health
Q1. A community health nurse is assigned to a densely populated urban
neighborhood experiencing increased emergency department visits for uncontrolled
hypertension. Which intervention best demonstrates a population-focused nursing
approach?
A. Teaching one client how to self-administer antihypertensive medication
B. Coordinating blood pressure screening events at local community centers
,C. Providing bedside discharge education to hospitalized clients
D. Monitoring a single client's sodium intake during home visits
Correct Answer: 🔴 B. Coordinating blood pressure screening events at local
community centers
Explanation: 🔹 Population-focused nursing targets health outcomes for entire
communities or groups rather than individual patients. Organizing community-wide
blood pressure screening events addresses prevention, early detection, and health
promotion for large populations. Options A, C, and D focus primarily on individual-
level care rather than broader public health intervention strategies.
Q2. During a windshield survey, a nurse observes multiple abandoned buildings,
inadequate street lighting, and limited grocery stores selling fresh produce. These
observations are most relevant to which concept?
A. Secondary prevention
B. Social determinants of health
C. Incidence rate calculation
D. Case management
Correct Answer: 🔴 B. Social determinants of health
Explanation: 🔹 Social determinants of health include environmental, economic, and
social conditions influencing health outcomes. Poor housing conditions, food deserts,
and unsafe neighborhoods contribute significantly to chronic disease and health
inequities. Secondary prevention focuses on early disease detection, while incidence
rates and case management are unrelated to these environmental observations.
Q3. A nurse is reviewing epidemiological data regarding a recent outbreak of hepatitis
A within a county. Which measure reflects the number of newly diagnosed cases
during a specific time period?
A. Mortality rate
B. Prevalence
,C. Incidence
D. Morbidity ratio
Correct Answer: 🔴 C. Incidence
Explanation: 🔹 Incidence refers to newly occurring cases within a defined population
during a specified time frame. This measure is critical for identifying emerging
outbreaks and monitoring disease transmission trends. Prevalence includes both new
and existing cases, while mortality measures deaths and morbidity broadly reflects
illness burden.
Q4. A public health nurse is implementing tertiary prevention strategies for adults with
chronic obstructive pulmonary disease (COPD). Which intervention best aligns with
tertiary prevention?
A. Conducting anti-smoking campaigns in schools
B. Administering influenza vaccines
C. Providing pulmonary rehabilitation services
D. Teaching hand hygiene to community members
Correct Answer: 🔴 C. Providing pulmonary rehabilitation services
Explanation: 🔹 Tertiary prevention focuses on reducing complications and
improving quality of life after disease development. Pulmonary rehabilitation helps
clients manage COPD and prevent further disability. Anti-smoking campaigns
represent primary prevention, while vaccinations and hand hygiene primarily focus
on disease prevention before significant illness occurs.
Q5. A nurse is evaluating a community program aimed at reducing childhood obesity.
Which outcome best demonstrates program effectiveness?
A. Increased attendance at pediatric clinics
B. Higher rates of obesity-related hospitalizations
C. Reduced body mass index trends among school-aged children
D. Increased fast-food restaurant sales in the area
, Correct Answer: 🔴 C. Reduced body mass index trends among school-aged
children
Explanation: 🔹 Effective obesity prevention programs should demonstrate
measurable improvements in population health indicators such as BMI reduction.
Increased hospitalization and fast-food sales would indicate worsening health trends.
Clinic attendance alone does not necessarily demonstrate improved health outcomes.
Q6. Which action by a community health nurse best reflects the principles of primary
prevention?
A. Referring clients with diabetes for retinal examinations
B. Facilitating smoking cessation classes for adolescents
C. Coordinating rehabilitation after stroke
D. Monitoring complications in clients with heart failure
Correct Answer: 🔴 B. Facilitating smoking cessation classes for adolescents
Explanation: 🔹 Primary prevention aims to prevent disease before it occurs.
Smoking cessation education reduces future risk for cardiovascular and respiratory
diseases. Retinal examinations represent secondary prevention, while rehabilitation
and complication monitoring are tertiary prevention activities.
Q7. A nurse identifies that a neighborhood has significantly higher asthma
hospitalization rates than surrounding areas. What is the nurse’s priority next step?
A. Immediately implement medication therapy plans
B. Report all affected families to social services
C. Conduct a community assessment to identify contributing factors
D. Close local schools until asthma rates decrease
Correct Answer: 🔴 C. Conduct a community assessment to identify contributing
factors
Explanation: 🔹 Community assessment is essential before designing interventions.
The nurse must investigate environmental triggers, housing conditions, pollution
