1. Which activity is an example of a public health policy intervention?
Answer: Regulating the advertising of alcohol
• Detailed Rationale: Public health policy interventions involve laws, regulations, or
formal rules enacted by governing bodies to influence population-level behaviors and
health outcomes. Regulating alcohol advertising directly alters the environment to reduce
exposure and demand, shifting the focus from individual choice to systemic protection.
2. What is the goal of health equity efforts in public health?
Answer: Ensuring that everyone has the opportunity to reach their full health potentials
• Detailed Rationale: Health equity means that everyone has a fair and just opportunity
to be as healthy as possible. This requires removing obstacles to health—such as poverty,
discrimination, and lack of access to good jobs, quality education, housing, and
healthcare—thereby giving all individuals equal footing to achieve optimal health.
3. What is a primary focus of tertiary prevention?
Answer: Managing the negative impact of an established disease
2
, • Detailed Rationale: Tertiary prevention takes place after a disease or injury has already
been diagnosed and established. Its primary objective is to slow or stop disease
progression, manage chronic conditions, prevent further complications, and maximize the
patient's remaining functionality and quality of life.
4. What is an example of secondary disease prevention?
Answer: Monitoring blood pressure following a new hypertension diagnosis
• Detailed Rationale: Secondary prevention focuses on early detection and prompt
intervention to halt the progression of a disease in its earliest stages. Monitoring a newly
diagnosed condition allows clinicians to track the disease, evaluate treatment efficacy,
and intervene before severe target-organ damage or clinical complications occur.
5. Which activity is an example of tertiary prevention?
Answer: Rehabilitation for stroke patients
• Detailed Rationale: Rehabilitation occurs after a major, irreversible clinical event
(such as a stroke) has taken place. Because the damage has already occurred, physical
and occupational therapies are utilized as tertiary prevention strategies to help the patient
regain skills, adapt to permanent disabilities, and avoid secondary complications.
6. What was a common practice in the Industrial Revolution to prevent the spread of
infectious diseases?
Answer: Sanitation and hygiene measures
• Detailed Rationale: The Industrial Revolution brought rapid urbanization,
overcrowding, and filthy living conditions, leading to massive outbreaks of cholera and
typhoid. Before the widespread acceptance of germ theory, public health pioneers
successfully combated these diseases by implementing environmental sanitation, clean
water supplies, and basic hygiene infrastructure.
7. What is a characteristic of a centralized public health structure?
Answer: Health policies and programs are determined by the state government.
