1. A community health nurse is reviewing the determinants of health. Which of the following
factors should the nurse identify as social determinants of health? (Select all that apply.)
A. Access to health care services
B. Genetic predisposition to diabetes
C. Availability of nutritious food options
D. Quality of local housing and infrastructure
E. Exposure to toxic substances in the environment
F. Individual’s educational attainment level
Correct Answer: A, C, D, F
Explanation: Social determinants of health are the conditions in the environments where
people are born, live, learn, work, play, worship, and age that affect a wide range of health
outcomes. Access to care, food security, housing quality, and education are all key
components of these social structures. Genetic factors and direct toxic exposures are
biological or environmental factors respectively, rather than social constructs.
,2. A public health nurse is applying the epidemiological triangle to track an outbreak of
influenza. Which factor represents the ‘agent’ in this model?
A. The influenza virus itself
B. The older adult population in the community
C. The crowded conditions at a local shelter
D. The seasonal change to colder temperatures
Correct Answer: A
Explanation: The agent is the physical, infectious, or chemical factor that causes the
disease, which in this case is the influenza virus. The host refers to the living being that the
agent or environment influences, such as the older adult population. The environment
includes the external factors like shelter conditions and temperature that allow
transmission to occur.
3. During a disaster response, a nurse is performing triage using the START (Simple Triage and
Rapid Treatment) system. A patient is found to be unconscious with a respiratory rate of 8
breaths/minute. Which color tag should the nurse assign?
A. Green (Minor)
B. Red (Immediate)
C. Yellow (Delayed)
D. Black (Deceased)
, Correct Answer: B
Explanation: A respiratory rate below 10 or above 30 breaths per minute in an adult
indicates an immediate life threat requiring a red tag. Red tags are reserved for those who
require immediate medical intervention to survive the next few hours. The nurse must
prioritize these individuals to maximize the number of lives saved during a mass casualty
incident.
4. The community health nurse is planning a primary prevention activity to address the
incidence of skin cancer. Which of the following activities should the nurse include?
A. Performing skin screenings for suspicious moles at a community health fair.
B. Educating high school students on the importance of using SPF 30+ sunscreen.
C. Providing support groups for individuals currently undergoing chemotherapy for
melanoma.
D. Assisting a patient with stage IV skin cancer to navigate palliative care services.
Correct Answer: B
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury through education and protective measures. Educational programs regarding
sunscreen usage aim to stop skin cancer before it starts. Screenings are secondary
prevention, and support groups or palliative care represent tertiary prevention.
