NR-442/NR442 Exam 2 V1 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is investigating the epidemiological triangle regarding a recent
outbreak of influenza. Which of the following describes the ‘environment’ in this model?
A. Crowded living conditions in a local nursing home.
B. The human host susceptible to the virus.
C. The influenza virus strain circulating in the population.
D. The age and vaccination status of the residents.
Correct Answer: A
Explanation: The environment in the epidemiological triangle refers to external factors
that allow for transmission of the agent to the host. In this scenario, crowded living
conditions facilitate the spread of the virus among individuals. Understanding these factors
is crucial for implementing effective control measures in community health nursing.
2. In the event of a mass casualty incident, a nurse is performing triage. A victim has a sucking
chest wound and is in respiratory distress but has a palpable pulse. Which color tag should
the nurse assign?
A. Black
B. Green
,C. Yellow
D. Red
Correct Answer: D
Explanation: A red tag indicates an immediate priority for victims with life-threatening
injuries who have a high chance of survival if treated quickly. A sucking chest wound
causes immediate respiratory compromise and requires urgent intervention. This
classification system ensures that resources are allocated to those with the most critical
needs first.
3. A nurse is working with a rural community to improve health outcomes. What is the most
significant barrier to healthcare access for residents in rural areas?
A. Lack of interest in healthcare services.
B. Distance to healthcare facilities and lack of transportation.
C. Excessive numbers of specialized clinics.
D. High levels of health literacy among the population.
Correct Answer: B
Explanation: Rural populations frequently face geographic isolation, which limits their
access to necessary medical services and specialists. The lack of public transportation
options in these areas further exacerbates the difficulty in reaching distant clinics. Nurses
must advocate for mobile clinics or telehealth services to bridge these gaps in care.
, 4. Using the ‘I-PREPARE’ mnemonic for environmental health assessments, what does the
first ‘E’ stand for?
A. Exercise history
B. Environmental concerns
C. Employment history
D. Eating habits
Correct Answer: B
Explanation: The ‘I-PREPARE’ tool is used by nurses to systematically evaluate potential
environmental exposures in patients. The first ‘E’ specifically asks about environmental
concerns related to the patient’s home, work, or community. This helps identifying toxins
or hazards that might be contributing to a patient’s current health status.
5. Which level of prevention is a nurse practicing when conducting a lead screening program
for children in an older urban neighborhood?
A. Primary Prevention
B. Quaternary Prevention
C. Tertiary Prevention
D. Secondary Prevention
Correct Answer: D
