Actual Q&A with Rationale (NSG440 Exam 3) |

1. A community health nurse is calculating the rate of new cases of COVID-19 in a specific
county over the past month. Which epidemiological measure is the nurse determining?
A. Prevalence rate
B. Mortality rate
C. Attack rate
D. Incidence rate
Correct Answer: D
Explanation: The incidence rate specifically measures the number of new cases of a
disease occurring within a population during a defined period of time. This differs from
prevalence, which includes both new and pre-existing cases. Understanding incidence is
crucial for identifying emerging health threats and assessing the effectiveness of
prevention programs within the community.
2. A nurse is working in a rural clinic and notices a high rate of respiratory issues among
children living near a local farm. Which environmental health concept best describes this
situation?
A. Point source pollution
B. Non-point source pollution
,C. Bioaccumulation
D. Environmental justice
Correct Answer: A
Explanation: Point source pollution refers to contamination that originates from a single,
identifiable location, such as a specific farm’s waste runoff or industrial discharge. Non-
point source pollution, conversely, comes from diffuse sources like general urban runoff.
Identifying the specific source is the first step in environmental mitigation and regulatory
reporting to protect public health.
3. A community health nurse is conducting an assessment of a neighborhood using the ‘I-
PREPARE’ mnemonic. Which of the following are components of this environmental health
assessment tool? Select all that apply.
A. Investigate potential exposures
B. Present work
C. Residence
D. Environmental concerns
E. Past work
F. Activities
G. Religion
H. Educate
,Correct Answer: A, B, C, D, E, F, H
Explanation: The I-PREPARE mnemonic is an essential tool for nurses to assess
environmental health risks by looking at Investigate, Present work, Residence,
Environmental concerns, Past work, Activities, Referrals, and Educate. It ensures that the
nurse covers all relevant history that might impact the client’s current health status due to
toxic exposures. Religion is not typically included in this specific environmental assessment
tool, although it is part of a broader cultural assessment.
4. Following a major flood, a community health nurse is tasked with ensuring the safety of
the local water supply. Which phase of the disaster management cycle does this action
represent?
A. Mitigation
B. Preparedness
C. Recovery
D. Response
Correct Answer: C
Explanation: The recovery phase involves actions taken to return the community to its
normal state and improve upon its previous condition. Ensuring safe water after a flood is a
critical part of restoring essential services and preventing secondary disease outbreaks.
This phase follows the immediate emergency response and precedes the new mitigation
efforts for future events.
, 5. Which level of prevention is a nurse implementing when teaching a group of migrant
farmworkers about the importance of wearing long sleeves and hats to prevent pesticide
exposure?
A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Quaternary prevention
Correct Answer: C
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury through education and protective measures. By teaching workers how to avoid
exposure, the nurse is reducing the risk before any harm occurs. This proactive approach is
the hallmark of community health nursing interventions aimed at vulnerable populations.
6. A nurse is reviewing the Sustainable Development Goals (SDGs) established by the United
Nations. Which of the following are included in these goals? Select all that apply.
A. No Poverty
B. Zero Hunger
C. Gender Equality
D. Colonization of Mars
E. Clean Water and Sanitation
