1. A community health nurse is applying the
nursing process at the community level. Which
action occurs during the planning phase?
A) Collecting demographic data from the
census bureau
B) Developing goals and objectives for a teen
pregnancy prevention program
C) Implementing a vaccination clinic at a local
school
D) Analyzing whether community health
outcomes have improved
Correct answer: B
Rationale: Planning involves developing goals,
objectives, and interventions based on
assessment data. Assessment is collecting
data. Implementation is carrying out the plan.
Evaluation measures outcomes.
,2. A nurse is using the epidemiological triangle
to investigate an outbreak of Legionnaires
disease. Which component of the triangle is the
contaminated water source?
A) Host
B) Agent
C) Environment
D) Vector
Correct answer: C
Rationale: The environment includes external
factors that allow transmission (contaminated
water source, temperature, pH). The agent is
Legionella bacteria. The host is the susceptible
person. Vectors are living transmitters
(mosquitoes, ticks), not applicable here.
3. A community health nurse is conducting a
windshield survey. Which observation is most
relevant to assessing community safety?
A) Number of churches in the area
B) Presence of streetlights and crosswalks
C) Types of restaurants available
D) Number of schools
,Correct answer: B
Rationale: Streetlights, crosswalks, sidewalks,
traffic signals, and lighting affect pedestrian
and vehicle safety. Churches, restaurants, and
schools are important for community
resources but not directly safety indicators.
4. A nurse is using the precede-proceed model
for health promotion planning. Which phase
involves identifying predisposing, enabling,
and reinforcing factors?
A) Social assessment
B) Epidemiological assessment
C) Educational and ecological assessment
D) Administrative and policy assessment
Correct answer: C
Rationale: The educational and ecological
assessment phase identifies predisposing
factors (knowledge, attitudes, beliefs),
enabling factors (skills, resources, barriers),
and reinforcing factors (rewards, feedback,
social support). Social assessment identifies
quality of life.
, 5. A community health nurse is providing
secondary prevention. Which activity is an
example of secondary prevention?
A) Teaching hand hygiene in elementary
schools
B) Administering influenza vaccines at a senior
center
C) Conducting mammography screening for
breast cancer
D) Providing cardiac rehabilitation after a heart
attack
Correct answer: C
Rationale: Secondary prevention focuses on
early detection of disease through screening
(mammography, blood pressure checks,
cholesterol screening). Hand hygiene and
vaccines are primary prevention. Cardiac
rehabilitation is tertiary prevention.
6. A nurse is investigating an outbreak of E.
coli O157:H7 linked to a county fair. Which
level of prevention is being implemented?
A) Primary prevention
B) Secondary prevention
