NR442/NR 442 Final Exam V1 | Community
Health Nursing Q&A with Rationale |
Chamberlain University
1. A community health nurse is planning a primary prevention strategy for a local senior
center. Which of the following interventions should the nurse include?
A. Providing influenza immunizations for all members.
B. Screening participants for early signs of glaucoma.
C. Conducting a support group for individuals with chronic arthritis.
D. Performing blood pressure checks to identify hypertension.
Correct Answer: A
Expert Explanation: Primary prevention aims to prevent the onset of disease through
proactive measures such as immunizations. Providing influenza vaccines helps build
immunity in the population before exposure occurs. In contrast, screenings represent
secondary prevention, while support groups for existing conditions fall under tertiary
prevention.
2. When applying the epidemiological triangle to a case of foodborne illness at a local school,
the nurse identifies the bacteria ‘Salmonella’ as which component?
A. The Host
B. The Environment
,C. The Vector
D. The Agent
Correct Answer: D
Expert Explanation: The agent is the animate or inanimate factor that must be present or
lacking for a disease or condition to develop. In this scenario, Salmonella is the biological
agent responsible for the illness. The host refers to the students, and the environment
includes the food handling conditions.
3. A nurse is performing a windshield survey of a new neighborhood. Which of the following
observations provides information about the community’s ‘social system’?
A. The condition of the roads and availability of public transit.
B. The presence of several churches and a community center.
C. The types of housing and age of the buildings.
D. The number of parks and green spaces available for recreation.
Correct Answer: B
Expert Explanation: Social systems include the institutions and groups that provide
support and structure to the community, such as religious organizations and community
centers. Physical infrastructure like roads and housing reflects the physical environment
rather than the social system itself. Identifying these systems helps the nurse understand
the resources available to the residents.
, 4. A community health nurse is evaluating the ‘prevalence’ of diabetes in a specific county.
Which of the following best defines this term?
A. The number of new cases of diabetes diagnosed in the last year.
B. The proportion of the population at risk for developing diabetes.
C. The death rate associated with diabetes complications.
D. The total number of people living with diabetes in the county at a specific time.
Correct Answer: D
Expert Explanation: Prevalence refers to the total number of existing cases in a
population at a specific point in time, providing a ‘snapshot’ of the disease burden.
Incidence, on the other hand, measures only the new cases occurring during a specific
period. Understanding prevalence is essential for planning long-term healthcare resource
allocation.
5. A nurse is providing teaching to a client who has a prescription for a Mantoux tuberculin
skin test. Which of the following statements should the nurse include?
A. ‘You will need to return in 24 hours to have the site checked.’
B. ‘A positive result means you have active tuberculosis.’
C. ‘The test is positive if there is a raised, hardened area at the site.’
D. ‘You should cover the site with a bandage after the injection.’
Correct Answer: C
