NUR 126 – COMMUNITY HEALTH NURSING Public Health
Nursing Study Guide Population Health, Community Assessment,
Disease Prevention, Health Promotion, and Comprehensive Review
Questions with Detailed Answers & Rationales
1. A community health nurse is conducting a needs assessment in a rural
community with limited access to healthcare. Which action should the nurse
take first to identify the community's health priorities?
A) Review epidemiological data and vital statistics
B) Conduct focus groups with community members
C) Interview local healthcare providers
D) Analyze existing health programs
Answer: A
Rationale: The community health nursing process begins with assessment.
Reviewing epidemiological data provides objective information about health
status, morbidity, and mortality. This data forms the foundation for identifying
health priorities. While focus groups and interviews provide valuable qualitative
data, quantitative data from vital statistics and epidemiology should be analyzed
first to establish baseline health indicators.
2. A public health nurse is applying the nursing process to a community
population. Which action demonstrates the "diagnosis" phase of the nursing
process at the community level?
A) Administering immunizations at a community health fair
B) Identifying that the community has a higher than average rate of childhood
obesity
C) Implementing a smoking cessation program in the workplace
D) Evaluating the effectiveness of a diabetes management program
Answer: B
Rationale: The nursing diagnosis phase involves identifying health problems,
risks, and strengths of the community population. Identifying higher than average
childhood obesity rates is an example of community-level diagnosis. Option A
represents intervention, C represents implementation/planning, and D represents
evaluation.
,3. A community health nurse is using the epidemiological triangle to
investigate an outbreak of foodborne illness. Which factor represents the
"host" component of the triangle?
A) Contaminated food supply
B) Bacteria in the food
C) Elderly individuals with compromised immune systems
D) Improper food handling practices
Answer: C
Rationale: The epidemiological triangle consists of agent, host, and environment.
The host is the susceptible human or animal population. Elderly individuals with
compromised immune systems represent a vulnerable host population. The
contaminated food supply is the environment, bacteria is the agent, and improper
handling is an environmental factor.
4. A community health nurse is implementing a primary prevention strategy.
Which intervention best exemplifies this level of prevention?
A) Screening for hypertension at a community health fair
B) Providing case management for patients with diabetes
C) Teaching healthy nutrition and exercise to adolescents
D) Administering influenza vaccine to elderly residents
Answer: C
Rationale: Primary prevention aims to prevent disease before it occurs. Teaching
healthy nutrition and exercise is primary prevention because it reduces risk factors
before disease develops. Screening (B) is secondary prevention. Case management
(B) and treatment (D) are tertiary prevention. Immunizations are also primary
prevention, but they specifically prevent infectious disease through a targeted
biological intervention. Health promotion education is a broader primary
prevention strategy.
5. A nurse is applying the principles of social determinants of health when
assessing a patient. Which factor is considered a social determinant of health?
,A) Age and gender
B) Genetic predisposition to heart disease
C) Access to safe housing and nutritious food
D) Blood pressure reading
Answer: C
Rationale: Social determinants of health are conditions in the environments where
people are born, live, learn, work, play, and age that affect health outcomes.
Access to safe housing and nutritious food is a key social determinant. Age,
gender, and genetics are biological determinants. Blood pressure is a health status
indicator.
6. A community health nurse is evaluating the effectiveness of a health
promotion program. Which measure indicates the program's impact on the
population?
A) Number of educational sessions conducted
B) Number of participants attending sessions
C) Decrease in preventable hospitalizations in the community
D) Participant satisfaction survey scores
Answer: C
Rationale: Outcome evaluation measures the impact of the program on health
status. A decrease in preventable hospitalizations indicates that the health
promotion program has effectively improved population health. Process evaluation
measures include number of sessions (A), attendance rates (B), and satisfaction
(D).
7. A public health nurse is using the health belief model to guide patient
education. Which patient statement indicates understanding of the model's
concept of "perceived susceptibility"?
A) "If I eat healthy and exercise, I can prevent heart disease."
B) "My father had a heart attack, so I might have one too."
C) "Exercising regularly will help me maintain a healthy weight."
D) "I believe I can walk for 30 minutes three times a week."
, Answer: B
Rationale: Perceived susceptibility is an individual's belief about their risk of
developing a health problem. The statement "My father had a heart attack, so I
might have one too" reflects an understanding of personal risk. Option A reflects
perceived benefits, C reflects perceived benefits, and D reflects self-efficacy.
8. A community health nurse is preparing to conduct a windshield survey.
Which activity is most appropriate during this assessment?
A) Reviewing medical records from the local clinic
B) Interviewing community leaders in their homes
C) Driving through the community to observe physical and social characteristics
D) Collecting blood samples for health screening
Answer: C
Rationale: A windshield survey is a community assessment method conducted by
driving through the community to observe environmental and social characteristics
such as housing conditions, safety, transportation, and available services. The other
options describe different assessment methods such as record review, key
informant interviews, and direct screening.
9. A nurse is working with a community that has a high rate of teenage
pregnancy. Which intervention represents a tertiary prevention strategy?
A) Teaching contraceptive methods in high schools
B) Providing prenatal care and parenting classes for teenage mothers
C) Implementing after-school programs for at-risk youth
D) Distributing condoms at community health centers
Answer: B
Rationale: Tertiary prevention focuses on reducing complications and improving
quality of life after a health problem has occurred. Providing prenatal care and
parenting support for teenage mothers who are already pregnant is tertiary
prevention. Options A, C, and D are primary prevention strategies.
