1. A public health nurse is investigating an outbreak of influenza in a local long-term care
facility. Which components represent the epidemiological triangle? (Select All That Apply)
A. Agent
B. Host
C. Environment
D. Policy
E. Cost
Correct Answer: ABC
Explanation: The epidemiological triangle consists of the agent, host, and environment.
The agent is the virus causing the infection, the host is the person affected, and the
environment is the setting where transmission occurs. Understanding these three elements
is essential for nurses to identify risks and implement control measures during an
outbreak.
2. Which of the following is considered a primary prevention intervention for chronic
obstructive pulmonary disease (COPD)?
A. Providing pulmonary rehabilitation classes
,B. Implementing a smoking cessation campaign in the community
C. Screening patients using spirometry
D. Prescribing bronchodilators to a patient with a new diagnosis
Correct Answer: B
Explanation: Primary prevention aims to prevent the onset of disease before it occurs. A
smoking cessation campaign targets the root cause of COPD by preventing exposure to
tobacco smoke. This contrasts with secondary prevention like screening and tertiary
prevention like rehabilitation.
3. A nurse is using the ‘I-PREPARE’ mnemonic to assess environmental exposure. Which of the
following areas should the nurse assess under the ‘P’ and ‘R’ sections? (Select All That Apply)
A. Past work
B. Psychosocial stress
C. Residence
D. Referrals and resources
E. Personal protective equipment
F. Recent travel
Correct Answer: ACD
Explanation: In the I-PREPARE model, ‘P’ stands for Present Work, ‘P’ also stands for Past
Work, and ‘R’ stands for Residence, Referrals/Resources, and Relevant information. This
, tool helps clinicians systematically evaluate environmental health risks in their patients. By
using this mnemonic, nurses can ensure they do not miss critical exposure history that
could impact health outcomes.
4. A community health nurse is conducting a windshield survey. Which of the following
observations provides information about the community’s social determinants of health?
A. The presence of grocery stores with fresh produce
B. The number of stray animals in the neighborhood
C. The architecture style of the residential buildings
D. The speed limit signs on the main road
Correct Answer: A
Explanation: Access to healthy food is a key social determinant of health (SDOH) that
directly impacts nutrition and chronic disease management. A windshield survey allows a
nurse to observe environmental factors like ‘food deserts’ or ‘food swamps’ within a
community. Identifying these barriers is the first step in planning population-level health
interventions.
5. In the disaster management cycle, which phase involves the implementation of strategies
to minimize the impact of a disaster before it occurs?
A. Preparedness
B. Response
C. Mitigation
