NURS4055 – Population & Community
Health Examination Questions & Answers
Question 1
A community health nurse is conducting a community assessment. Which data
source would provide the most accurate information about the leading causes of
death in the community?
A) Hospital discharge summaries
B) State vital statistics (death certificates)
C) Local newspaper obituaries
D) Patient satisfaction surveys
Answer: B) State vital statistics (death certificates)
Vital statistics, including death certificates, are the primary source for mortality
data. They provide cause of death, age, race, and location, allowing calculation of
age-adjusted mortality rates and identification of leading causes of death in a
community.
Question 2
A nurse is using the epidemiological triangle to understand an outbreak of hepatitis
A in a community. The three components of the epidemiological triangle are:
A) Person, place, time
B) Agent, host, environment
C) Incidence, prevalence, mortality
D) Primary, secondary, tertiary prevention
Answer: B) Agent, host, environment
,The epidemiological triangle (or triad) includes: agent (cause of disease, e.g.,
hepatitis A virus), host (susceptible person), and environment (external factors
enabling transmission). Changing any component can control or prevent disease.
Question 3
A community health nurse is planning a vaccination clinic for influenza. Which
level of prevention is this?
A) Primary prevention
B) Secondary prevention
C) Tertiary prevention
D) Quaternary prevention
Answer: A) Primary prevention
Primary prevention aims to prevent disease before it occurs (health promotion,
specific protection). Vaccination is primary prevention. Secondary prevention is
early detection (screening). Tertiary prevention manages existing disease to
prevent complications.
Question 4
A nurse is calculating the incidence rate of a new disease in a community. The
formula for incidence rate is:
A) (Number of existing cases / total population) × 1000
B) (Number of new cases during a time period / population at risk during that
period) × multiplier
C) (Number of deaths from disease / total population) × 100,000
D) (Number of cases / number of people tested) × 100
Answer: B) (Number of new cases during a time period / population at risk
during that period) × multiplier
,Incidence measures new cases over a specific time period in a population at risk.
Prevalence measures existing cases (old + new) at a point in time. Incidence is
crucial for understanding disease risk and transmission.
Question 5
A community health nurse is using the “Healthy People 2030” framework. Healthy
People 2030 provides:
A) Mandatory regulations for hospitals
B) National health objectives to improve health and reduce health disparities
C) Funding for individual patient care
D) Licensure requirements for nurses
Answer: B) National health objectives to improve health and reduce health
disparities
Healthy People is a science-based, 10-year national agenda for improving health. It
sets measurable objectives for health promotion, disease prevention, and
eliminating health disparities across populations.
Question 6
A nurse is investigating a foodborne illness outbreak in a community. The nurse
creates a graph showing the number of cases by date of symptom onset. The
resulting epidemic curve suggests a point source outbreak (sharp peak, rapid
decline). This pattern indicates:
A) Person-to-person transmission
B) A single common exposure at a specific time (e.g., contaminated food at a
single meal)
C) Ongoing continuous exposure
D) Seasonal variation
Answer: B) A single common exposure at a specific time (e.g., contaminated
food at a single meal)
, A point source epidemic curve shows a rapid increase and gradual decrease,
indicating a common exposure at a single time. Propagated curves (person-to-
person) show multiple peaks. Continuous exposure shows a plateau.
Question 7
Which of the following is an example of a “social determinant of health” that
affects community well-being?
A) A patient’s genetic predisposition to diabetes
B) The availability of affordable housing and safe parks in a neighborhood
C) A hospital’s readmission rate
D) The efficacy of a new medication
Answer: B) The availability of affordable housing and safe parks in a
neighborhood
Social determinants of health (SDOH) are conditions in the environments where
people live, learn, work, and play that affect health outcomes. They include
economic stability, education, healthcare access, neighborhood environment, and
social context.
Question 8
A nurse is conducting a windshield survey of a community. What is the primary
purpose of a windshield survey?
A) To measure air pollution levels with instruments
B) To observe the physical environment, housing, infrastructure, and resources of a
community through direct observation
C) To interview community leaders
D) To analyze hospital discharge data
Answer: B) To observe the physical environment, housing, infrastructure, and
resources of a community through direct observation
