1. A nurse is working in a disaster management role. Which of the following activities best
represents the mitigation phase of disaster management?
A. Advocating for stronger building codes in a flood-prone area.
B. Developing a community-wide emergency response plan.
C. Setting up a temporary shelter for displaced residents.
D. Conducting triage at the site of a mass casualty incident.
Correct Answer: A
Explanation: Mitigation involves actions taken to prevent or reduce the cause, impact, and
consequences of a disaster. Advocating for building codes targets long-term risk reduction
before an event occurs. This phase emphasizes structural and non-structural measures to
minimize future vulnerability.
2. A community health nurse is identifying barriers to healthcare for rural populations. Which
factors are commonly associated with rural health disparities? (Select all that apply)
A. Lack of public transportation options.
B. Higher numbers of uninsured individuals.
,C. Shortage of healthcare specialists.
D. Cultural preference for traditional healers.
E. Long travel distances to facilities.
F. Overabundance of tertiary care centers.
Correct Answer: A, B, C, E
Explanation: Rural populations often face significant geographic isolation and economic
challenges such as higher uninsured rates. The scarcity of specialized providers and the
lack of reliable public transport further exacerbate these disparities. Addressing these
issues requires a multifactorial approach involving telehealth and policy changes.
3. In the epidemiological triangle, which of the following represents the ‘environment’ factor?
A. The genetic susceptibility of a patient to a virus.
B. The virulence of a bacterial strain.
C. The age and nutritional status of a child.
D. The presence of stagnant water in a residential area.
Correct Answer: D
Explanation: The environment refers to the extrinsic factors that affect the agent and the
opportunity for exposure. Stagnant water serves as a physical environmental factor that
can harbor vectors like mosquitoes. Understanding this balance is crucial for implementing
effective community interventions.
, 4. A nurse is performing secondary prevention activities in the community. Which action
should the nurse take?
A. Screening school-aged children for scoliosis.
B. Administering the influenza vaccine to elderly residents.
C. Teaching a diabetic patient how to perform foot care.
D. Leading a support group for stroke survivors.
Correct Answer: A
Explanation: Secondary prevention focuses on early detection and prompt intervention to
limit the severity of a disease. Scoliosis screening is a classic example of identifying a
condition in its preclinical stage. This differs from primary prevention, which focuses on
initial prevention, and tertiary, which focuses on rehabilitation.
5. A nurse is using the ‘I PREPARE’ mnemonic to assess environmental exposure. What does
the ‘E’ in the mnemonic stand for?
A. Education and Evaluation.
B. Environmental Emergencies.
C. Ethics and Enforcement.
D. Employment and Environmental Concerns.
