Actual Q&A with Rationale (NSG440 Exam 4) |

1. A community health nurse is identifying barriers to healthcare access for a rural
population. Which factors should the nurse include? (Select all that apply)
A. Lack of public transportation
B. Predictable weather patterns
C. Inadequate provider numbers in the area
D. Distance from specialized medical facilities
E. Lower health literacy levels among residents
Correct Answer: ACDE
Explanation: Rural populations frequently face significant geographic isolation and a lack
of public transportation, making physical access to clinics difficult. Furthermore, these
areas are often designated as Health Professional Shortage Areas (HPSAs) due to a limited
number of primary and specialty care providers. Lower health literacy and socioeconomic
challenges further exacerbate the difficulty in navigating complex healthcare systems.
2. Which level of prevention is a nurse implementing when conducting a blood pressure
screening at a local senior center?
A. Primary Prevention
,B. Quaternary Prevention
C. Tertiary Prevention
D. Secondary Prevention
Correct Answer: D
Explanation: Secondary prevention focuses on early detection and intervention to limit
the severity of a disease. Blood pressure screening is a classic example of secondary
prevention because it aims to identify hypertension in its asymptomatic stages. By
detecting health issues early, the nurse can facilitate prompt treatment and prevent long-
term complications such as stroke or heart disease.
3. The epidemiological triangle consists of which three components?
A. Risk, Susceptibility, and Immunity
B. Bacteria, Virus, and Parasite
C. Person, Place, and Time
D. Agent, Host, and Environment
Correct Answer: D
Explanation: The epidemiological triangle is a fundamental model used to study the cause
and spread of infectious diseases. It emphasizes the interaction between the agent (the
cause of the disease), the host (the organism harboring the disease), and the environment
(external factors that allow transmission). Understanding these three pillars allows public
health officials to identify intervention points to break the cycle of disease.
,4. A nurse is assessing a migrant farmworker for occupational health risks. Which findings are
common in this population? (Select all that apply)
A. Pesticide exposure
B. Tuberculosis
C. Heat-related illnesses
D. Dental caries
E. Skin cancer
Correct Answer: ABCDE
Explanation: Migrant farmworkers are subject to numerous environmental and
occupational hazards, including chronic exposure to pesticides and extreme heat. Due to
poor living conditions and limited access to care, they are also at higher risk for
communicable diseases like tuberculosis and chronic issues like dental caries. Frequent sun
exposure without adequate protection also increases their long-term risk for skin
malignancies.
5. A public health nurse is using the ‘I PREPARE’ mnemonic to assess environmental exposure.
What does the ‘E’ in ‘PREPARE’ stand for in the context of the initial assessment?
A. Environmental justice
B. Environmental concerns
C. Education level
, D. Employment history
Correct Answer: B
Explanation: The ‘I PREPARE’ mnemonic is a clinical tool used to facilitate systematic
environmental health histories. The first ‘E’ specifically prompts the nurse to ask the client
about environmental concerns related to their home, work, or community. This proactive
approach helps identify potential toxins or hazards that might otherwise be overlooked
during a standard physical examination.
6. When responding to a mass casualty incident, which color tag would the nurse assign to a
patient who has a patent airway but is unconscious with a massive head injury and minimal
chance of survival?
A. Red
B. Yellow
C. Black
D. Green
Correct Answer: C
Explanation: In disaster triage, the black tag is used for deceased victims or those whose
injuries are so extensive that they are not expected to survive even with care. This
prioritization is necessary to ensure that limited resources are directed toward those with
the highest probability of survival. This ethical framework, known as utilitarianism, aims to
do the greatest good for the greatest number of people during a crisis.
