1. A community health nurse is participating in a disaster preparedness drill. Which of the
following activities occur during the ‘Preparedness’ phase of disaster management? (Select
All That Apply)
A. Developing a mobilization plan for emergency personnel.
B. Conducting community-wide triage drills.
C. Identifying vulnerable populations within the community.
D. Initiating debris removal and structural repair.
E. Creating a communication plan for local authorities.
F. Providing psychological first aid to survivors.
Correct Answer: A, B, C, E
Explanation: The preparedness phase involves actions taken before a disaster to facilitate
an effective response and minimize damage. Activities include planning, training,
identifying high-risk groups, and establishing communication networks to ensure
readiness. Debris removal is part of recovery, and psychological first aid is typically part of
the immediate response phase or early recovery phase depending on the context of the
intervention.
,2. Which of the following describes the ‘Agent’ in the epidemiological triangle when
considering a client with Tuberculosis?
A. A crowded living environment.
B. An immunocompromised host.
C. The Mycobacterium tuberculosis bacterium.
D. Poor nutritional status.
Correct Answer: C
Explanation: In the epidemiological triangle, the agent is the animate or inanimate factor
that must be present or lacking for a disease or condition to develop. Mycobacterium
tuberculosis is the biological agent responsible for causing the infection in the host. The
environment includes social and physical conditions, while the host refers to the human
who can get the disease.
3. A public health nurse is reviewing environmental health risks. What does the ‘I’ represent
in the I-PREPARE mnemonic used to assess environmental exposure history?
A. Internal medicine history.
B. Infection control measures.
C. Investigate potential exposures.
D. Identified toxic substances.
Correct Answer: C
,Explanation: The I-PREPARE mnemonic stands for Investigate potential exposures,
Present work, Residence, Environmental concerns, Past work, Activities, Referrals and
Resources, and Educate. Investigating potential exposures is the critical first step in
identifying if a client’s symptoms could be related to their environment. This tool helps
clinicians collect data systematically to identify environmental health risks in a clinical
setting.
4. The nurse is discussing global health outcomes. Which metric is used to measure the total
loss of health due to specific diseases and injuries, including both premature death and
disability?
A. Prevalence rate.
B. Case fatality rate.
C. Incidence rate.
D. Disability-Adjusted Life Years (DALY).
Correct Answer: D
Explanation: The Disability-Adjusted Life Year (DALY) is a measure of overall disease
burden, expressed as the number of years lost due to ill-health, disability, or early death. It
was developed to quantify the burden of diseases, injuries, and risk factors at the
population level. This metric allows health officials to compare the impact of different
conditions across various populations and time periods.
, 5. A nurse is working in a rural community. Which of the following are significant barriers to
healthcare access commonly faced by rural populations? (Select All That Apply)
A. Lack of public transportation systems.
B. Overabundance of specialized practitioners.
C. Longer travel distances to healthcare facilities.
D. Limited health insurance coverage among the self-employed.
E. Strict urban zoning laws.
Correct Answer: A, C, D
Explanation: Rural residents often face geographic isolation, resulting in long travel times
and distances to reach providers. The lack of public transit exacerbates this problem, as
does the higher rate of uninsured or underinsured individuals due to seasonal or self-
employed work patterns. Specialization is typically lower in rural areas compared to urban
centers, rather than being overabundant.
6. When conducting a community assessment, the nurse utilizes the ‘Windshield Survey.’
What is the primary purpose of this method?
A. To conduct in-depth interviews with key community stakeholders.
B. To analyze statistical data from the US Census Bureau.
C. To provide a preliminary visual overview of the community’s health and environment.
D. To diagnose individual health conditions within a specific neighborhood.
