**Question 1**
A community health nurse is planning a primary prevention program for a rural community with high
rates of cardiovascular disease. Which of the following interventions is most appropriate?
A. A hypertension screening clinic at the local senior center
B. A community-wide education campaign on healthy eating and physical activity
C. Cardiac rehabilitation for clients post-myocardial infarction
D. Home visits to monitor blood pressure for clients with known hypertension
💫ANSWER✔️✔️: B. Primary prevention aims to prevent disease before it occurs. Education on healthy
eating and physical activity targets the general population to reduce risk factors.
💫RATIONALE✔️✔️: Screening (A) is secondary prevention. Cardiac rehab (C) and home visits for known
hypertension (D) are tertiary prevention (managing existing disease).

**Question 2**
,A nurse is investigating a cluster of gastrointestinal illnesses among attendees of a community picnic.
The nurse interviews affected individuals and creates a timeline of events. Which epidemiological term
describes this process?
A. Descriptive epidemiology
B. Analytic epidemiology
C. Experimental epidemiology
D. Surveillance
💫ANSWER✔️✔️: A. Descriptive epidemiology involves characterizing the outbreak by person (who),
place (where), and time (when). This includes creating an epidemic curve and timeline.
💫RATIONALE✔️✔️: Analytic epidemiology (B) tests hypotheses (case-control or cohort studies).
Experimental epidemiology (C) involves clinical trials. Surveillance (D) is ongoing data collection.

**Question 3**
A community health nurse is conducting a windshield survey of a neighborhood. Which of the following
findings is most relevant to assessing community health resources?
A. The presence of litter and abandoned buildings
B. The location of the nearest hospital and community health center
C. The number of parks and recreational facilities
D. The condition of sidewalks and streetlights
💫ANSWER✔️✔️: B. A windshield survey assesses resources (healthcare facilities, pharmacies, schools,
food sources, transportation). The location of a hospital and health center directly impacts access to
care.
,💫RATIONALE✔️✔️: Litter/abandoned buildings (A) indicate environmental hazards. Parks (C) relate to
physical activity. Sidewalks/lighting (D) relate to safety. All are relevant, but healthcare resources are
most directly tied to health outcomes.

**Question 4**
A nurse is working with a migrant farmworker population. Which of the following barriers to healthcare
is most unique to this population?
A. Lack of health insurance
B. Language barriers
C. Mobility and lack of continuity of care due to seasonal migration
D. Low health literacy
💫ANSWER✔️✔️: C. Migrant farmworkers move seasonally, leading to fragmented care, lost medical
records, and inability to establish a medical home. While other barriers exist, mobility is the most
unique.
💫RATIONALE✔️✔️: Lack of insurance (A), language (B), and low literacy (D) are common barriers in many
underserved populations but are not unique to migrant workers.

**Question 5**
A community health nurse is evaluating a smoking cessation program. Which outcome measure best
indicates program effectiveness at the population level?
A. Number of participants who attended all sessions
, B. Percentage of participants who report smoking cessation at 6 months post-intervention
C. Number of brochures distributed
D. Participant satisfaction survey scores
💫ANSWER✔️✔️: B. The most meaningful outcome is behavior change (cessation) sustained over time (6
months). Process measures (attendance, brochures) and satisfaction do not measure true effectiveness.
💫RATIONALE✔️✔️: Process measures (A, C) do not indicate outcomes. Satisfaction (D) is a surrogate
measure. Sustained cessation is the gold standard.

**Question 6**
A nurse is responding to a disaster where a chemical plant explosion has occurred. The nurse is assigned
to the decontamination area. Which of the following is a priority action?
A. Remove all clothing and jewelry from victims before they enter the decontamination tent
B. Rinse victims with warm water and soap, starting from the head and moving downward
C. Transport contaminated victims directly to the emergency department for treatment
D. Have victims shower with cold water only to prevent chemical absorption
💫ANSWER✔️✔️: A. Clothing and jewelry should be removed before decontamination because they can
trap chemicals. Decontamination should occur in a designated area, not in the ED (C). Water should be
tepid (not cold, D). Rinse from head to toe (B) is correct after removal.
💫RATIONALE✔️✔️: Decontamination reduces secondary contamination of healthcare workers and
facilities. Victims should be decontaminated before entering the treatment area.
