NRS 425 Exam 3 V2 | NRS 425 Health Promotion
and Population Health | Actual Q&A with Rationale
(NRS425 Exam 3) | Grand Canyon University
1. A public health nurse is using the I-PREPARE mnemonic to assess a client’s environmental
health risks. Which of the following components should be included in this assessment?
Select all that apply.
A. Investigate potential exposures
B. Present work history
C. Residence location and age of home
D. Environmental concerns in the community
E. Past work history
F. Activities and hobbies
G. Referrals and resources
H. Educate the client on prevention
Correct Answer: A, B, C, D, E, F, G, H
Explanation: The I-PREPARE tool is a systematic framework used by nurses to collect a
comprehensive environmental health history. It ensures that the nurse evaluates
everything from workplace hazards to domestic risks like lead paint in older residences. By
,utilizing all these components, the nurse can better identify environmental triggers for a
client’s health issues and provide targeted education.
2. A community health nurse is planning an immunization clinic for the local flu season.
Which level of prevention does this activity represent?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: A
Explanation: Primary prevention focuses on preventing the occurrence of a disease or
injury before it happens. Immunizations are a classic example of this because they aim to
build immunity in the population to avoid infection entirely. This proactive approach
reduces the overall burden of disease within the community.
3. In the epidemiological triangle, a nurse identifies that a client is suffering from a
respiratory infection caused by a specific bacteria in a crowded living environment. Which
element represents the ‘Environment’ in this scenario?
A. The bacteria causing the infection
B. The client who is ill
C. The crowded living conditions
,D. The antibiotics prescribed
Correct Answer: C
Explanation: The epidemiological triangle consists of the agent, the host, and the
environment. In this case, the environment refers to the external factors, such as crowded
living conditions, that facilitate the transmission of the agent to the host. Understanding
these interactions helps nurses identify where to intervene to break the chain of infection.
4. Which of the following defines health literacy in the context of population health?
A. The ability to read at a high school level
B. The degree to which individuals can obtain, process, and understand basic health
information to make appropriate decisions
C. A person’s knowledge of medical terminology and anatomy
D. The frequency with which a patient visits their primary care physician
Correct Answer: B
Explanation: Health literacy involves more than just reading; it encompasses the ability to
navigate the healthcare system and understand instructions for treatment. Low health
literacy is a significant barrier to health equity and is linked to poorer health outcomes
across various populations. Nurses must assess a client’s health literacy to ensure that
educational materials are culturally and linguistically appropriate.
, 5. A nurse is responding to a mass casualty incident and uses the START triage system. A
victim is found to be unconscious with a respiratory rate of 8 and a weak pulse. What color
tag should this victim receive?
A. Green (Minor)
B. Yellow (Delayed)
C. Black (Deceased)
D. Red (Immediate)
Correct Answer: D
Explanation: In the START triage system, a red tag indicates that the patient requires
immediate life-saving intervention to survive. This patient’s unconscious state and
abnormal respiratory rate signify a critical threat to their airway and breathing. Promptly
identifying red-tag patients is essential for prioritizing resources during a disaster
response.
6. A nurse is providing education to a patient newly diagnosed with Type 2 Diabetes about
foot care and blood sugar monitoring. This intervention is classified as:
A. Primary prevention
B. Secondary prevention
C. Primordial prevention
D. Tertiary prevention
