Section 1: Epidemiology & Disease Prevention
1. A community health nurse is investigating an outbreak of hepatitis A in a
rural town. Which epidemiological concept is the nurse using when calculating
the attack rate?
• A. Prevalence
• B. Incidence proportion
• C. Case fatality rate
• D. Herd immunity threshold
Rationale: Attack rate is a type of incidence proportion, measuring new cases in a
specific population during a limited time period (e.g., an outbreak). Prevalence
includes old and new cases. Case fatality rate measures deaths. Herd immunity
threshold is the proportion immune to prevent spread.
2. A nurse is conducting a community assessment. Which data source provides
the most accurate information about the leading causes of death in the
community?
• A. Vital statistics reports
• B. Hospital discharge data
• C. School absenteeism records
• D. Police incident reports
,Rationale: Vital statistics (birth/death certificates) legally document causes of death.
Hospital data show morbidity, not mortality. School and police data are not primary
mortality sources.
3. A nurse is planning a primary prevention activity for cardiovascular disease.
Which intervention should the nurse implement?
• A. Screening blood pressure at a health fair
• B. Teaching a low-sodium cooking class
• C. Providing cardiac rehabilitation after a myocardial infarction
• D. Measuring BMI in a clinic
Rationale: Primary prevention prevents disease before it occurs. Teaching healthy
habits (low-sodium diet) is primary. Screening (BP, BMI) is secondary. Rehabilitation
is tertiary.
4. A community has 1,200 residents. During a flu season, 60 new cases of
influenza occurred. What is the cumulative incidence?
• A. 2%
• B. 5%
• C. 10%
• D. 20%
Rationale: Cumulative incidence = (new cases / total population at risk) × 100 = (60
/ 1200) × 100 = 5%.
5. A nurse uses the epidemiological triangle to analyze a tuberculosis outbreak.
Which factor represents the "agent"?
• A. Overcrowded housing
• B. Mycobacterium tuberculosis
• C. Elderly population
• D. Poor ventilation
, Rationale: The epidemiological triangle: agent (causative organism: M. tuberculosis),
host (elderly), environment (overcrowding, poor ventilation).
Section 2: Program Planning & Evaluation
6. A nurse completes a needs assessment and finds that teenage pregnancy
rates are high. Which is the first step in program planning?
• A. Identify modifiable risk factors
• B. Secure funding from local grants
• C. Implement a sex education program
• D. Hire additional staff for the clinic
Rationale: After needs assessment, the next step is analyzing determinants
(modifiable risk factors) before designing interventions. Implementation and funding
come later.
7. A nurse is evaluating a smoking cessation program. Which outcome indicates
summative evaluation?
• A. Number of participants who attended the first session
• B. Participant satisfaction with handouts
• C. Reduction in smoking rate at 12 months post-program
• D. Percentage of teaching objectives met during sessions
Rationale: Summative evaluation measures long-term outcomes (e.g., smoking rate
reduction). Formative evaluation (A, B, D) measures process during implementation.
8. A nurse uses the PRECEDE-PROCEED model. Which phase involves identifying
quality of life issues?
• A. Social assessment
• B. Epidemiological assessment
• C. Educational assessment
• D. Administrative assessment
