NR-442/NR442 Final Exam V3 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is conducting a lead screening for children at a local clinic. This
activity represents which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Primordial prevention
Correct Answer: B
Explanation: Secondary prevention focuses on early detection and screening to identify
diseases in their earliest stages. Screening for lead poisoning allows for immediate
intervention before significant physiological damage occurs. This level of care aims to
reduce the impact of a disease that has already developed but may not yet be symptomatic.
2. During a disaster response, a nurse identifies a victim with a sucking chest wound and
labored breathing. Using the START triage system, which color tag should be assigned?
A. Green
B. Yellow
C. Red
,D. Black
Correct Answer: C
Explanation: A red tag signifies an ‘immediate’ priority for victims with life-threatening
injuries who have a chance of survival with prompt treatment. A sucking chest wound
compromises the airway and breathing, making it a top priority. Nurses must prioritize
these individuals to maximize the number of lives saved during a mass casualty event.
3. A nurse is using the ‘I PREPARE’ mnemonic to assess environmental exposure. What does
the ‘E’ in the mnemonic represent?
A. Evidence
B. Environmental factors
C. Education
D. Exit strategy
Correct Answer: B
Explanation: The ‘I PREPARE’ tool is used to systematically assess an individual’s
environmental exposure history. The ‘E’ stands for Environmental factors, which prompts
the nurse to ask about potential hazards in the home or community. This assessment is
critical for identifying links between a patient’s symptoms and their environment.
4. Which of the following describes the ‘Agent’ in the epidemiological triad regarding
Influenza?
A. The virus itself
, B. A cold, damp climate
C. An immunocompromised elderly person
D. A crowded nursing home
Correct Answer: A
Explanation: The epidemiological triad consists of the agent, the host, and the
environment. The agent is the animate or inanimate factor that must be present for a
disease to develop, such as the influenza virus. Understanding this relationship helps
community health nurses implement targeted interventions to break the chain of infection.
5. A home health nurse is performing an admission assessment. Which finding is the highest
priority for intervention regarding safety?
A. Lack of a bathroom grab bar
B. The presence of a small throw rug
C. Frayed electrical cords in the living room
D. Inadequate lighting in the hallway
Correct Answer: C
Explanation: Frayed electrical cords present an immediate risk for fire and electrocution,
which are acute life-safety hazards. While throw rugs and lack of grab bars are fall risks,
fire hazards often take precedence in emergency planning. The nurse must prioritize
hazards that can cause catastrophic injury or death to the patient and their family.
