SECTION ONE: QUESTIONS 1–100
1. A public health nurse is analyzing the high prevalence of asthma in an urban neighborhood. Which of the following social determinants of health is most likely
contributing to this issue?
A. Genetic predisposition
B. Lack of access to specialty care
C. Proximity to industrial zones and heavy traffic
D. Patient non-compliance with inhaler use
🟢 C. Proximity to industrial zones and heavy traffic
🔴 RATIONALE: Environmental factors such as air pollution from industrial areas and traffic are primary social determinants that contribute to respiratory conditions like asthma
in urban populations.
2. Which level of prevention is a public health department implementing when it hosts a screening clinic for scoliosis at a local middle school?
,A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
🟢 B. Secondary prevention
🔴 RATIONALE: Screening activities are classified as secondary prevention because they aim to detect a condition in its early stages before clinical symptoms become severe.
3. An epidemiologist is studying a sudden outbreak of foodborne illness after a community picnic. Which measure of frequency is most appropriate to describe this
occurrence?
A. Prevalence rate
B. Case-fatality rate
C. Attack rate
D. Crude death rate
🟢 C. Attack rate
🔴 RATIONALE: The attack rate is a specific type of incidence rate used during outbreaks to measure the proportion of a population that becomes ill after exposure to a specific
source.
4. When developing a program to reduce teenage pregnancy, the public health official first reviews data regarding local culture, education levels, and economic status. This
represents which phase of the nursing process?
A. Implementation
B. Evaluation
C. Assessment
D. Planning
🟢 C. Assessment
🔴 RATIONALE: Assessment involves the systematic collection of data regarding the community’s specific characteristics and needs before a plan or intervention is developed.
5. A nurse is investigating a cluster of lead poisoning cases in a historic district. Which is the most likely source of exposure for pediatric patients in this area?
A. Contaminated soil near highways
B. Lead-based paint in older housing
C. Imported plastic toys
D. Well water from deep aquifers
🟢 B. Lead-based paint in older housing
, 🔴 RATIONALE: In historic or older districts, lead-based paint in residential buildings remains the most common source of lead exposure for children via dust or peeling chips.
6. A community health center provides directly observed therapy (DOT) for a patient diagnosed with tuberculosis. This strategy primarily addresses which ethical principle?
A. Autonomy
B. Justice
C. Beneficence
D. Fidelity
🟢 C. Beneficence
🔴 RATIONALE: Beneficence involves taking action to benefit others. DOT ensures the patient completes treatment, benefiting both the individual's health and public safety.
7. Which of the following best describes "Herd Immunity" within a population?
A. Every individual in the community is vaccinated
B. The virus has mutated to become less virulent
C. A sufficient portion of the population is immune, limiting the spread of disease
D. The disease has been completely eradicated globally
🟢 C. A sufficient portion of the population is immune, limiting the spread of disease
🔴 RATIONALE: Herd immunity occurs when the high prevalence of immunity in a group protects non-immune individuals by breaking the chain of transmission.
8. In a research study, the probability of an event occurring in an exposed group compared to an unexposed group is known as:
A. Odds Ratio
B. Relative Risk
C. Standard Deviation
D. Confidence Interval
🟢 B. Relative Risk
🔴 RATIONALE: Relative risk is a measure of association in cohort studies that compares the risk of an outcome between an exposed group and an unexposed group.
9. A public health policy mandates that all children must receive certain vaccinations before enrolling in public school. This is an example of:
A. Police power
B. Federal supremacy
C. Voluntary compliance
D. Civil litigation
🟢 A. Police power
