Concepts of Community-Based Nursing
Q&A with Rationale | Fortis College
1. A community health nurse is conducting a screening for hypertension at a local shopping
mall. This activity represents which level of prevention?
A. Primary prevention
B. Tertiary prevention
C. Secondary prevention
D. Quaternary prevention
Correct Answer: C
Expert Explanation: Secondary prevention focuses on early detection and screening of
diseases to limit the impact of the condition. By identifying high blood pressure early,
patients can receive treatment before complications occur. This level of care is distinct
from primary prevention, which focuses on health promotion and disease prevention.
2. In the epidemiological triangle, which of the following refers to the living or nonliving
factor that must be present for a disease to develop?
A. The agent
B. The environment
C. The host
,D. The vector
Correct Answer: A
Expert Explanation: The agent is the causative factor, such as a bacterium, virus, or
chemical, that must be present for disease to occur. The host is the human or animal that is
susceptible to the agent. The environment includes external factors that influence the
interaction between the host and the agent.
3. A nurse is performing a windshield survey of a neighborhood. Which of the following
observations is most indicative of the community’s socioeconomic status?
A. The presence of public parks
B. The availability of grocery stores with fresh produce
C. The number of churches in the area
D. The presence of stray animals
Correct Answer: B
Expert Explanation: Access to fresh produce and full-service grocery stores is a strong
indicator of a community’s economic resources and ‘food desert’ status. Areas with low
socioeconomic status often have more convenience stores than supermarkets. This
observation helps the nurse assess the nutritional barriers faced by the population.
4. A home health nurse is visiting an elderly patient for the first time. Which environmental
observation poses the greatest safety risk?
A. A small dog barking in the yard
, B. A pile of newspapers on a side table
C. A dim light in the kitchen
D. Unsecured throw rugs in the hallway
Correct Answer: D
Expert Explanation: Unsecured throw rugs are a major cause of falls in the elderly
population due to tripping hazards. Falls can lead to significant morbidity, including
fractures and head injuries. The nurse must educate the patient on removing these hazards
to ensure a safe living environment.
5. A patient with terminal lung cancer is being referred to hospice care. Which statement by
the nurse best describes the goal of hospice?
A. Hospice focuses on curing the disease using experimental therapies.
B. Hospice care is exclusively provided in a hospital setting.
C. Hospice is only for patients who can no longer communicate.
D. Hospice aims to provide comfort and quality of life for those with a limited prognosis.
Correct Answer: D
Expert Explanation: Hospice care is intended to provide palliative care and support for
patients who are near the end of life. The focus is on symptom management and
psychological support rather than curative treatment. It generally requires a physician-
certified life expectancy of six months or less.
