NR442/NR 442 Exam 2 V2 | Community
Health Nursing Q&A with Rationale |
Chamberlain University
1. A community health nurse is conducting a health education session for high school
students regarding the prevention of sexually transmitted infections (STIs). Which level of
prevention does this activity represent?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: A
Expert Explanation: Primary prevention aims to prevent the onset of disease or injury
before it occurs. In this scenario, providing education helps students make informed
choices to avoid infection altogether. This level of care focuses on health promotion and
risk reduction in healthy populations.
2. A nurse is performing a tuberculosis (TB) skin test for a group of migrant farmworkers.
Which level of prevention is being implemented?
A. Primary prevention
B. Primordial prevention
,C. Tertiary prevention
D. Secondary prevention
Correct Answer: D
Expert Explanation: Secondary prevention focuses on early detection and screening to
identify diseases in their earliest stages. TB skin testing is a classic example of screening
aimed at identifying asymptomatic individuals who may have been exposed. Early
identification allows for prompt treatment and prevents further transmission within the
community.
3. Which intervention should a community health nurse include when planning tertiary
prevention for a client who recently suffered a stroke?
A. Providing education on healthy eating habits
B. Screening for high blood pressure at a local health fair
C. Administering a flu vaccine to prevent respiratory complications
D. Referring the client to a physical therapy program for rehabilitation
Correct Answer: D
Expert Explanation: Tertiary prevention aims to minimize the impact of an established
disease and prevent further complications or disability. Rehabilitation through physical
therapy helps the stroke survivor regain function and improve their quality of life. This
stage of prevention occurs after the clinical diagnosis and initial treatment phase.
, 4. In the epidemiological triangle, which factor represents the person or animal that harbors
the disease-causing agent?
A. Host
B. Environment
C. Vector
D. Agent
Correct Answer: A
Expert Explanation: The host is the living being that is affected by the agent and is
influenced by the environment. Factors such as age, genetics, and immune status determine
the host’s susceptibility to a particular disease. Understanding host characteristics is vital
for epidemiologists when mapping out disease patterns and vulnerabilities.
5. An occupational health nurse is assessing the risk of noise-induced hearing loss in a
manufacturing plant. Which element of the epidemiological triangle does the noise
represent?
A. Risk factor
B. Host
C. Environment
D. Agent
Correct Answer: D
