1. A community health nurse is planning a smoking cessation program for a local high school.
Which level of prevention does this represent?
A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Quaternary prevention
Correct Answer: C
Explanation: Primary prevention aims to prevent disease or injury before it ever occurs.
By educating high school students on smoking cessation, the nurse is attempting to prevent
the onset of nicotine addiction and long-term respiratory issues. This intervention is
applied to a population that is generally healthy but at risk for developing unhealthy
behaviors.
2. A nurse is investigating an outbreak of foodborne illness at a local restaurant. Which
epidemiological model is most appropriate for identifying the interaction between the host,
the agent, and the environment?
A. The Web of Causality
,B. The Health Belief Model
C. The Epidemiological Triangle
D. The Wheel of Causation
Correct Answer: C
Explanation: The Epidemiological Triangle consists of the agent, host, and environment,
which is the traditional model of infectious disease causation. It helps researchers visualize
how these three factors interact to cause a specific disease outbreak. In this scenario, it
would help identify the contaminated food (agent), the susceptible patrons (host), and the
restaurant conditions (environment).
3. A nurse is conducting a windshield survey. Which of the following observations provide
data about the community’s environmental health? Select all that apply.
A. Presence of garbage or litter on the streets
B. Availability of public transportation and sidewalks
C. Condition of housing and proximity to industrial plants
D. Prevalence of chronic diseases in the local clinic
E. Presence of parks and recreational green spaces
Correct Answer: A,B,C,E
Explanation: A windshield survey is an observational method used to assess a
community’s characteristics and environmental factors while driving or walking through
,the area. Options A, B, C, and E are direct observations of the physical environment that
impact health outcomes. Option D requires clinical data and cannot be observed during a
physical tour of the neighborhood.
4. Which of the following is an example of secondary prevention?
A. Conducting blood pressure screenings at a senior center
B. Providing immunizations to infants
C. Referring a stroke patient to physical therapy
D. Educating a patient on a low-sodium diet for hypertension
Correct Answer: A
Explanation: Secondary prevention focuses on early detection and intervention to reduce
the impact of a disease that has already occurred. Screenings, such as blood pressure
checks, allow for the identification of asymptomatic individuals who may have a condition.
This stage follows primary prevention and precedes tertiary rehabilitation efforts.
5. A community health nurse is identifying determinants of health for a group of migrant
workers. Which factor is considered a social determinant of health (SDOH)?
A. Genetic predisposition to diabetes
B. Age and gender of the workers
C. Access to affordable and healthy food
D. Individual choices regarding exercise
, Correct Answer: C
Explanation: Social determinants of health are the conditions in which people are born,
grow, live, work, and age. Access to affordable and healthy food is a structural condition
within the environment that impacts health outcomes. Unlike genetics or age, SDOH are
often influenced by policy and economic distribution.
6. During a disaster response, a nurse uses the START triage system. A victim is found with a
respiratory rate of 32 breaths per minute. Which color tag should the nurse assign?
A. Red (Immediate)
B. Yellow (Delayed)
C. Green (Minor)
D. Black (Deceased)
Correct Answer: A
Explanation: According to the START (Simple Triage and Rapid Treatment) protocol, any
patient with a respiratory rate greater than 30 breaths per minute is classified as
‘Immediate’ and given a red tag. This indicates that the patient requires urgent medical
attention to survive. Nurses must quickly assess respiration, perfusion, and mental status
to prioritize care during mass casualty events.
