NUR 206/NUR206 Exam 4 V3 | Community Nursing
Concepts Q&A with Rationale | Fortis College
1. A community health nurse is conducting an initial visit with a migrant farmworker family.
Which of the following is the priority assessment for this population according to the official
syllabus?
A. Current vaccination records of children
B. Availability of primary care clinics nearby
C. Dietary habits and nutritional intake
D. Exposure to pesticides and skin conditions
Correct Answer: D
Explanation: Migrant farmworkers are at high risk for occupational hazards, specifically
pesticide exposure which can lead to immediate and long-term health issues. Assessment
of the skin and respiratory system for signs of toxicity is a critical safety intervention. This
priority reflects the environmental health focus required in community nursing curricula.
2. When applying the epidemiological triad to a case of influenza, which of the following is
considered the ‘host’?
A. The Influenza virus
B. Cold weather and low humidity
C. An unvaccinated elderly person
,D. Contaminated surfaces and doorknobs
Correct Answer: C
Explanation: In the epidemiological triad, the host is the living organism susceptible to the
infection, which in this case is the unvaccinated individual. The virus represents the agent,
while weather and surfaces represent the environment. Understanding this balance is
essential for community-based interventions and disease control.
3. A nurse is planning a primary prevention activity for a local senior center. Which of the
following activities should the nurse include?
A. Assisting with physical therapy exercises after a hip replacement
B. Conducting blood pressure screenings for hypertension
C. Facilitating a support group for stroke survivors
D. Providing education on the benefits of a low-sodium diet
Correct Answer: D
Explanation: Primary prevention focuses on health promotion and the prevention of
disease occurrence through education and immunizations. Educational sessions regarding
diet aim to prevent the onset of chronic conditions before they start. Screening is
secondary prevention, while support groups and rehab are tertiary prevention.
4. During a mass casualty incident triage, a nurse identifies a victim with a sucking chest
wound and severe respiratory distress. Which color tag should the nurse assign?
A. Red
, B. Yellow
C. Green
D. Black
Correct Answer: A
Explanation: A red tag indicates an immediate priority for victims with life-threatening
injuries who have a high chance of survival if treated quickly. A sucking chest wound
compromises the airway and breathing, making it a top priority in disaster triage. This
categorization is a fundamental skill in community disaster response protocols.
5. A community health nurse is investigating a foodborne illness outbreak. To calculate the
attack rate, what information must the nurse obtain first?
A. The number of people who became ill after eating the food
B. The total population of the town
C. The mortality rate associated with the illness
D. The incubation period of the pathogen
Correct Answer: A
Explanation: The attack rate is a specific form of incidence used during outbreaks,
calculated by dividing the number of new cases by the total number of people exposed.
Identifying the number of ill individuals is the numerator necessary for this calculation.
This metric allows the nurse to determine the severity and source of the epidemic.
