community health nursing?
A. Providing influenza vaccinations at a community health fair.
B. Teaching a diabetic patient how to self-administer insulin.
C. Conducting a blood pressure screening at a local senior center.
D. Leading a support group for individuals recovering from substance abuse.
Correct Answer: A
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury. Providing vaccinations is a proactive measure that builds immunity before
exposure to the pathogen occurs. This level of prevention targets healthy populations to
reduce the overall incidence of specific health conditions.
2. A nurse is working to improve the health of a specific population by focusing on social
determinants of health. Which action should the nurse prioritize?
A. Distributing free samples of over-the-counter medications.
B. Updating the clinic’s filing system to electronic health records.
C. Advocating for affordable housing and improved public transportation.
,D. Ordering more diagnostic equipment for the local emergency room.
Correct Answer: C
Explanation: Social determinants of health include the conditions in which people are
born, grow, live, work, and age. Affordable housing and transportation directly impact a
person’s ability to maintain health and access services. Addressing these upstream factors
is essential for reducing health inequities within the community.
3. When applying the epidemiological triangle to a case of foodborne illness, which factor
represents the ‘agent’?
A. The contaminated poultry consumed by the victims.
B. The weakened immune systems of the elderly attendees.
C. The crowded conditions at the picnic where the food was served.
D. Salmonella bacteria found in the stool samples.
Correct Answer: D
Explanation: The epidemiological triangle consists of the agent, the host, and the
environment. The agent is the animate or inanimate factor that must be present or absent
for a disease or condition to develop, such as the Salmonella bacteria. The poultry is the
vehicle or source, the environment is the picnic setting, and the attendees are the hosts.
4. A community health nurse is conducting a community assessment using the ‘windshield
survey’ method. Which observation is most relevant to this type of assessment?
A. Reviewing the local census data for mortality rates.
, B. Interviewing the mayor regarding future infrastructure plans.
C. Analyzing the results of blood lead level tests from the local school.
D. Noting the presence of grocery stores and green spaces while driving.
Correct Answer: D
Explanation: A windshield survey is an informal assessment where the nurse drives
through a community to observe its physical environment and characteristics. This method
provides objective data about the community’s boundaries, housing quality, and available
resources like grocery stores. It is often the first step in a comprehensive community
assessment to identify strengths and weaknesses.
5. According to the Health Belief Model, which factor is most likely to motivate a client to
participate in a smoking cessation program?
A. The cost of the program being fully covered by insurance.
B. The client’s belief that they are personally at risk for lung cancer.
C. A workplace policy that prohibits smoking on the premises.
D. Receiving a brochure about the dangers of second-hand smoke.
Correct Answer: B
Explanation: The Health Belief Model suggests that behavior change is driven by perceived
susceptibility and perceived severity of a health condition. If a client believes they are at
high risk for a serious illness like cancer, they are more likely to take preventive action.
