5. Disaster Preparedness and Management
6. Global Health and Primary Health Care
1. A public health nurse is analyzing an outbreak of an infectious disease in a local school district.
The nurse notes that the incidence rate has spiked while the prevalence rate remains relatively
stable. Which of the following conclusions should the nurse draw regarding this outbreak?
A. The disease is becoming chronic in the population
B. The disease has a high transmission rate but a short duration
C. The healthcare system is effectively managing the disease
D. The population has developed herd immunity
Answer: B [Correct Answer]
Rationale: Incidence measures new cases, indicating a rapid spread of the pathogen, while
prevalence measures the total burden of existing cases. If incidence is high but prevalence is
stable, the cases must be resolving quickly through recovery or death, suggesting a short
, duration. A, C, and D do not align with the mathematical relationship between incidence and
prevalence in an acute outbreak.
CORRECT ANSWER : B
2. A nurse is conducting a community health assessment in a neighborhood with high rates of
childhood asthma. Which environmental factor should the nurse investigate as a primary
contributor to this health disparity?
A. The availability of recreational facilities
B. Proximity to major industrial or high-traffic transportation corridors
C. The socioeconomic status of the residents
D. The quality of local public schools
Answer: B [Correct Answer]
Rationale: Proximity to industrial zones or high-traffic roads increases exposure to air
pollutants like particulate matter and nitrogen dioxide, which are direct triggers for asthma
exacerbations. While A, C, and D are important social determinants, B represents a direct
environmental health hazard linked to respiratory pathophysiology.
CORRECT ANSWER : B
3. A community health nurse is designing a disaster response plan for a rural town following a
major flood. Which intervention is the highest priority during the immediate recovery phase?
A. Screening for long-term mental health disorders
B. Assessing and ensuring the safety of the public water supply
C. Organizing volunteer debris removal crews
D. Establishing long-term temporary housing
Answer: B [Correct Answer]
Rationale: In the immediate post-flood environment, the primary threat to public health is the
contamination of water sources, which can lead to widespread waterborne illnesses like cholera
or dysentery. This is a life-safety priority. A, C, and D are secondary to the immediate prevention
of infectious disease outbreaks.
CORRECT ANSWER : B
,4. A nurse is working with a vulnerable population experiencing homelessness. The nurse plans to
implement a primary prevention strategy to address health outcomes. Which action is most
appropriate?
A. Providing wound care for infected foot ulcers
B. Providing free influenza and pneumococcal vaccinations at a mobile clinic
C. Coordinating legal services for housing advocacy
D. Treating patients for chronic hypertension
Answer: B [Correct Answer]
Rationale: Primary prevention aims to prevent disease before it occurs. Vaccinations prevent
infection in a high-risk group. A and D are tertiary preventions (managing established disease),
and C is a social intervention that, while beneficial, is not a direct health-protective medical
prevention strategy.
CORRECT ANSWER : B
5. A community nurse is reviewing the "Epidemiological Triangle" for a patient with Lyme disease.
Which component represents the "Agent"?
A. The deer tick
B. The Borrelia burgdorferi bacterium
C. The forest environment
D. The human host
Answer: B [Correct Answer]
Rationale: In the epidemiological triangle, the agent is the microbial organism that causes the
disease. The tick (A) is the vector, the forest (C) is the environment, and the human (D) is the
host. Understanding these distinctions is fundamental to interrupting the chain of infection.
CORRECT ANSWER : B
6. A nurse is evaluating the effectiveness of a community-wide smoking cessation program. Which
metric provides the most accurate evidence of the program's long-term success in improving
community health?
A. The number of participants who completed the seminar
, B. The 12-month post-intervention smoking abstinence rate
C. The number of nicotine patches distributed
D. Participant satisfaction survey scores
Answer: B [Correct Answer]
Rationale: Outcome evaluation measures the actual health change, which in this case is
sustained smoking cessation. Participation numbers (A), distribution numbers (C), and survey
scores (D) are output or process metrics, which do not measure actual health improvement.
CORRECT ANSWER : B
7. A community nurse is practicing in a culturally diverse setting. A client refuses standard Western
medical treatment for a condition, opting instead for a traditional remedy that the nurse knows is
ineffective. What is the most appropriate action for the nurse?
A. Insist that the client follow the evidence-based medical plan
B. Assess the client’s beliefs and find a way to incorporate culturally acceptable care
C. Report the client to the medical board for non-compliance
D. Discharge the client from the clinic for refusing care
Answer: B [Correct Answer]
Rationale: Cultural competence requires the nurse to negotiate care that respects the client's
worldview while maintaining safety. Forcing care (A) or terminating care (D) is unethical and
counterproductive. B promotes therapeutic communication and patient-centered, holistic health
outcomes.
CORRECT ANSWER : B
8. A nurse is assessing the health of a migrant worker community. Which factor poses the greatest
barrier to these individuals accessing primary healthcare services?
A. Lack of interest in preventative medicine
B. Legal status and fear of deportation
C. A lack of available medical providers in the area
D. Their educational level regarding health
