NUR 426 Exam 4: Community Health Nursing Theory &
Application V2 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. A nurse is using the ‘I PREPARE’ mnemonic to assess a client’s environmental health. What does the ‘P’ in
‘PREPARE’ stand for?
A. Past work
B. Pollutants
C. Present work
D. Personal habits
Ans: C
Explanation: The correct choice is B because the first ‘P’ in the mnemonic stands for Present work. This
assessment tool is designed to help health professionals systematically evaluate a client’s environmental
exposure. By asking about current employment, the nurse can identify specific workplace hazards such as
chemicals or physical stressors. Other options like past work occur later in the mnemonic sequence.
Understanding these exposures is vital for diagnosing and treating environment-related illnesses
effectively.
2. In the epidemiological triangle, which of the following is considered an ‘Agent’?
A. Human host
B. Genetic predisposition
C. Climatic conditions
D. Bacteria or viruses
Ans: D
,Explanation: Option C is correct because agents are the infectious or non-infectious causes of disease.
The epidemiological triangle consists of the host, the environment, and the agent itself. Bacteria and
viruses represent biological agents that directly invade the body to cause harm. Humans are considered
hosts, while climatic conditions belong to the environment category. Distinguishing between these
elements allows nurses to target interventions at the specific cause of a health issue.
3. A community health nurse is conducting a screening for tuberculosis in a local shelter. Which level of
prevention does this represent?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Ans: B
Explanation: The correct answer is B because screening is the hallmark of secondary prevention. This
level of care focuses on early detection and prompt intervention to limit the impact of a disease. Primary
prevention involves immunizations or education to prevent the disease before it occurs. Tertiary
prevention aims to rehabilitate individuals already diagnosed with a chronic condition. Effective
screening in high-risk populations like shelters helps control the spread of infectious diseases.
4. When assessing a rural community, which barrier to healthcare access should the nurse anticipate as
most significant?
A. Oversupply of specialist providers
B. Cultural preference for traditional medicine
C. Higher rates of employer-sponsored insurance
, D. Lack of public transportation
Ans: D
Explanation: Option B is correct as rural areas frequently lack robust public transportation systems. This
geographic isolation makes it difficult for residents to reach clinics or hospitals for routine care. Unlike
urban areas, rural regions usually suffer from a shortage of specialists rather than an oversupply. Many
rural residents are also uninsured or underinsured compared to their urban counterparts. Addressing
transportation barriers is a critical component of improving health outcomes in rural populations.
5. Which of the following is a characteristic of the ‘Recovery’ phase in disaster management?
A. Assessing the community’s potential for disasters
B. Performing triage on victims at the scene
C. Conducting drills and training sessions
D. Restoring essential services and permanent housing
Ans: D
Explanation: The correct choice is C because the recovery phase focuses on returning the community to
a functional state. This phase begins when the immediate danger has passed and involves long-term
rebuilding efforts. Assessment and drills are part of the mitigation and preparedness phases respectively.
Triage is an activity associated with the response phase of a disaster. Successful recovery requires
collaboration between local government, health agencies, and community members.
6. A nurse is performing triage after a mass casualty event. A victim with a minor laceration who is able to
walk is assigned which color tag?
A. Red
B. Yellow
