1. Which statement best describes the primary purpose of health
sciences as an interdisciplinary field, particularly in relation to the
prevention of disease, promotion of wellness, diagnosis and treatment
of illness, rehabilitation, and improvement of population health
outcomes?
A. To focus exclusively on the diagnosis and surgical treatment of individual
patients
B. To study only the biological mechanisms responsible for infectious
diseases
C. To integrate knowledge from multiple disciplines to understand health,
prevent disease, provide care, and improve individual and population well-
being
,D. To prepare students exclusively for administrative positions within
hospitals
Rationale: Health sciences is inherently interdisciplinary and combines
biological, behavioral, social, environmental, clinical, and public-health
knowledge to promote health, prevent disease, and improve outcomes for
individuals and communities.
2. Which concept most accurately distinguishes health from the mere
absence of disease when considering the physical, psychological, and
social dimensions of an individual's life?
A. Health is determined exclusively by laboratory test results
B. Health refers only to physical strength and athletic ability
C. Health is a multidimensional state involving physical, mental, and social
well-being rather than simply the absence of disease
D. Health is determined entirely by a person's genetic inheritance
Rationale: Health is multidimensional and encompasses physical, mental,
and social well-being, meaning that a person may have no diagnosed
disease yet still experience poor health because of psychological, social, or
functional limitations.
3. A health sciences professional is evaluating why residents of a
particular community experience unusually high rates of respiratory
, illness. Which approach best reflects the interdisciplinary nature of
health sciences?
A. Examine only the residents' genetic profiles
B. Examine only the medications prescribed to affected residents
C. Consider environmental exposures, occupational conditions,
socioeconomic factors, health behaviors, genetics, access to care, and
biological mechanisms together
D. Determine only whether the residents have a family history of asthma
Rationale: Complex health outcomes generally result from interactions
among biological, behavioral, environmental, social, and healthcare
factors, requiring an interdisciplinary approach rather than a single
explanatory perspective.
4. Which level of disease prevention is primarily concerned with
preventing a disease or injury before it occurs by addressing risk
factors and promoting healthy behaviors?
A. Tertiary prevention
B. Secondary prevention
C. Rehabilitation
D. Primary prevention
, Rationale: Primary prevention occurs before disease develops and includes
measures such as vaccination, health education, exercise promotion,
smoking prevention, and reduction of environmental risks.
5. Which example best represents secondary prevention in a population
at risk for colorectal cancer?
A. Providing hospice care to patients with advanced cancer
B. Teaching children about the dangers of tobacco use
C. Performing recommended screening tests to identify precancerous
lesions or early cancer
D. Providing physical rehabilitation after cancer treatment
Rationale: Secondary prevention focuses on early detection and prompt
intervention, and screening can identify disease or precancerous changes
before they produce advanced clinical manifestations.
6. Which activity is most appropriately classified as tertiary prevention?
A. Administering childhood immunizations
B. Educating adolescents about healthy nutrition
C. Screening adults for hypertension
D. Providing rehabilitation to restore function after a disabling stroke
Rationale: Tertiary prevention aims to reduce complications, disability, and
functional impairment after a disease or injury has already developed.
