Question 1: A community health nurse is conducting a windshield survey. Which
of the following best describes the primary purpose of this assessment method?
A. To collect detailed demographic data from local government databases
B. To observe the physical environment and social conditions of a community
C. To conduct interviews with key community informants
D. To analyze health statistics from the local health department
CORRECT ANSWER: B. To observe the physical environment and social
conditions of a community
Rationale: A windshield survey is a visual observation of a community conducted
by driving or walking through it. Its primary purpose is to assess the physical
environment, housing conditions, social interactions, and available resources,
providing subjective, firsthand data that complements objective statistics.
Question 2: Which of the following is the most appropriate definition of
community health nursing?
A. Nursing care provided exclusively to individuals in their homes
B. A synthesis of nursing theory and public health science aimed at promoting the
health of populations
C. Clinical nursing practice focused on acute care within a community hospital
D. The provision of medical care to underserved populations in clinic settings
CORRECT ANSWER: B. A synthesis of nursing theory and public health science
aimed at promoting the health of populations
Rationale: Community health nursing integrates nursing science with public
health principles to promote and protect the health of populations. It
encompasses a wide range of settings and focuses on health promotion, disease
prevention, and health maintenance at the population level.
,Question 3: A nurse is applying the epidemiological triad to a community
experiencing an outbreak of foodborne illness. Which component represents
the contaminated food?
A. Host
B. Agent
C. Environment
D. Vector
CORRECT ANSWER: C. Environment
Rationale: The epidemiological triad consists of agent, host, and environment. The
contaminated food is the vehicle through which the agent is transmitted to the
host, making it part of the environment component. The environment includes all
external factors that influence the agent and host interaction.
Question 4: Which of the following levels of prevention is best exemplified by a
community-wide vaccination program?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
CORRECT ANSWER: A. Primary prevention
Rationale: Primary prevention aims to prevent disease or injury before it occurs.
Community-wide vaccination programs are a classic example of primary
prevention because they immunize individuals before they are exposed to
infectious agents, thereby preventing disease onset.
Question 5: A community health nurse is investigating an outbreak of measles in
a local school. What is the first step in the outbreak investigation process?
A. Implementing control measures immediately
B. Establishing the existence of an outbreak
C. Performing laboratory testing on affected students
D. Conducting a case-control study
CORRECT ANSWER: B. Establishing the existence of an outbreak
,Rationale: The first step in outbreak investigation is to determine whether the
observed number of cases exceeds the expected number for that population and
time period. This establishes the existence of an outbreak before proceeding with
further investigation and control measures.
Question 6: Which of the following is a core function of public health as defined
by the Institute of Medicine?
A. Direct patient care in hospital settings
B. Assessment, policy development, and assurance
C. Pharmaceutical dispensing and management
D. Surgical intervention for community members
CORRECT ANSWER: B. Assessment, policy development, and assurance
Rationale: The Institute of Medicine identifies three core functions of public
health: assessment (monitoring health status), policy development (developing
policies to address health needs), and assurance (ensuring the provision of
essential health services). These functions guide public health practice at all
levels.
Question 7: A nurse is calculating the incidence rate of a disease. Which of the
following formulas is correct?
A. (Number of existing cases / Total population) × 100,000
B. (Number of new cases / Total population at risk) × 100,000
C. (Number of deaths / Total population) × 100,000
D. (Number of new cases / Number of existing cases) × 100
CORRECT ANSWER: B. (Number of new cases / Total population at risk) ×
100,000
Rationale: Incidence rate measures the occurrence of new cases of a disease in a
population at risk during a specified time period. The formula is the number of
new cases divided by the population at risk, multiplied by a standard population
size (often 100,000) to create a rate.
Question 8: Which type of study design is most appropriate for investigating a
rare disease?
, A. Prospective cohort study
B. Randomized controlled trial
C. Case-control study
D. Cross-sectional study
CORRECT ANSWER: C. Case-control study
Rationale: Case-control studies are efficient for investigating rare diseases
because they start with the outcome (cases with the disease) and look backward
to identify exposures. This design requires fewer subjects than cohort studies
when the disease is rare, making it the most practical and cost-effective choice.
Question 9: A community health nurse is working with a population
experiencing health disparities. Which term best describes the unjust and
avoidable differences in health status among different population groups?
A. Health inequity
B. Health inequality
C. Health disparity
D. Health variation
CORRECT ANSWER: A. Health inequity
Rationale: Health inequity refers to differences in health status that are unjust,
avoidable, and rooted in systemic social and economic disadvantages. While
health disparity is a broader term for any difference, health inequity specifically
emphasizes the ethical and social justice dimensions of these differences.
Question 10: Which of the following best describes the concept of cultural
humility in community health nursing?
A. Memorizing cultural practices of specific ethnic groups
B. Recognizing one's own cultural biases and committing to lifelong learning
C. Applying the same care standards to all cultural groups
D. Avoiding discussions of culture to prevent stereotyping
CORRECT ANSWER: B. Recognizing one's own cultural biases and committing to
lifelong learning
