NR442/NR 442 Final Exam V2 | Community
Health Nursing Q&A with Rationale |
Chamberlain University
1. A community health nurse is conducting a windshield survey of a local neighborhood.
Which of the following observations provides information about the ‘physical environment’
subsystem?
A. The presence of several faith-based organizations and community centers.
B. The condition of housing and the amount of green space available.
C. A high number of individuals waiting at a local bus stop.
D. A large population of school-aged children playing in a park.
Correct Answer: B
Expert Explanation: The physical environment subsystem in a windshield survey
specifically looks at the structural components of the community such as housing
conditions, zoning, and open spaces. Observing the condition of buildings and green spaces
helps the nurse understand the physical stressors or assets of the community. This data is
essential for identifying potential health risks related to the living environment.
2. A nurse is planning a primary prevention activity for a group of migrant farmworkers.
Which of the following interventions should the nurse include?
A. Providing education on the proper use of personal protective equipment for pesticide
application.
,B. Conducting screening for tuberculosis exposure.
C. Treating skin rashes caused by contact with toxic plants.
D. Managing blood glucose levels for workers diagnosed with diabetes.
Correct Answer: A
Expert Explanation: Primary prevention focuses on preventing the initial occurrence of a
disease or injury. Providing education on the use of personal protective equipment (PPE)
helps prevent exposure to harmful pesticides before health issues arise. This proactive
approach is a hallmark of public health nursing and focuses on health promotion and risk
reduction.
3. In the epidemiological triangle, which of the following is considered an ‘agent’ factor?
A. A person’s genetic predisposition to a specific disease.
B. The presence of standing water where mosquitoes breed.
C. The socio-economic status of a community population.
D. The chemical composition of a toxic pollutant in the air.
Correct Answer: D
Expert Explanation: The epidemiological triangle consists of the agent, host, and
environment. An agent is the factor that causes the disease, which can be biological,
chemical, or physical; in this case, the toxic pollutant is a chemical agent. Understanding the
agent is crucial for developing targeted interventions to break the chain of transmission or
exposure.
,4. A nurse is triaging victims at the scene of a mass casualty incident. A victim is unconscious,
has a respiratory rate of 34/min, and has a radial pulse. Using the START triage system, which
color tag should the nurse assign?
A. Green
B. Yellow
C. Black
D. Red
Correct Answer: D
Expert Explanation: The START (Simple Triage and Rapid Treatment) system uses
respiratory rate, perfusion, and mental status to categorize victims. A respiratory rate over
30/min automatically places the victim in the ‘Immediate’ or Red category. These
individuals require priority medical attention because their condition is life-threatening
but potentially treatable.
5. A community health nurse is working to improve the health literacy of a vulnerable
population. Which action is the most effective for the nurse to take?
A. Provide medical brochures written at a 12th-grade reading level.
B. Use complex medical terminology to ensure technical accuracy.
C. Use the ‘teach-back’ method to verify the client’s understanding of instructions.
D. Limit teaching sessions to one-way lectures to save time.
, Correct Answer: C
Expert Explanation: The teach-back method is a evidence-based strategy that asks clients
to explain information back in their own words to confirm comprehension. This is
particularly important for populations with low health literacy to ensure they can manage
their care safely. Improving health literacy is a key component of reducing health
disparities in the community.
6. Which of the following is an example of secondary prevention for a patient with a family
history of hypertension?
A. Regular blood pressure screenings at a local health fair.
B. Teaching the patient about a low-sodium diet.
C. Prescribing antihypertensive medication to a patient with a blood pressure of 150/90.
D. Providing cardiac rehabilitation services after a myocardial infarction.
Correct Answer: A
Expert Explanation: Secondary prevention aims for early detection and treatment of a
disease before it progresses or symptoms become severe. Screening for blood pressure
allows for early identification of hypertension in at-risk individuals. This level of
prevention is vital for reducing the long-term morbidity associated with chronic conditions.
7. A nurse is using the I-PREPARE mnemonic to assess a client’s environmental exposure.
What does the ‘E’ in the mnemonic stand for?
A. Employment history
