NR-442/NR442 Exam 1 V2 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is conducting a windshield survey. Which of the following
observations provides information about the community’s environmental health?
A. The number of churches and religious centers
B. The presence of lead-based paint in older housing
C. The availability of public transportation routes
D. The variety of ethnic grocery stores available
Correct Answer: B
Explanation: Environmental health focuses on physical factors in the surroundings that
can impact human health. Identifying lead-based paint is a critical environmental
assessment because it poses significant risks for lead poisoning, particularly in children.
Other options like transportation and grocery stores relate to infrastructure and social
determinants but are not primarily environmental hazards.
2. Which level of prevention is a nurse practicing when providing a support group for
individuals recovering from substance abuse?
A. Primary prevention
B. Secondary prevention
,C. Quaternary prevention
D. Tertiary prevention
Correct Answer: D
Explanation: Tertiary prevention aims to minimize the impact of long-term disease and
disability. A support group for individuals already recovering from substance abuse helps
prevent relapse and promotes rehabilitation. This distinguishes it from primary
prevention, which prevents the onset of abuse, and secondary prevention, which involves
early screening.
3. A nurse is using the ‘I PREPARE’ mnemonic to assess environmental exposure. What does
the ‘E’ in the mnemonic stand for?
A. Emergency response
B. Environmental justice
C. Everyday activities
D. Environmental factors
Correct Answer: D
Explanation: The ‘I PREPARE’ mnemonic is a tool used by nurses to systematically
evaluate environmental health history. The ‘E’ stands for Environmental Factors, which
encourages the nurse to ask about the home environment and surrounding area. This helps
identify potential toxins such as radon, carbon monoxide, or nearby industrial pollutants.
, 4. When applying the Epidemiological Triad, a nurse identifies a virus as which component?
A. Host
B. Environment
C. Agent
D. Vector
Correct Answer: C
Explanation: The Agent is the physical, chemical, or infectious factor that must be present
for a disease to occur. In this case, the virus is the biological agent responsible for the
illness. The host is the living being affected, while the environment refers to external
factors that facilitate transmission.
5. A community health nurse is analyzing the infant mortality rate of a city. This data is
primarily used to:
A. Determine the success of geriatric care programs
B. Assess the overall health status of the population
C. Measure the effectiveness of high school sex education
D. Predict the future need for pediatric oncology services
Correct Answer: B
Explanation: Infant mortality rate is widely considered one of the most important
indicators of a community’s overall health and well-being. It reflects the adequacy of
