Question 1: Which of the following had the greatest impact
on average life expectancy?(A) Vaccinations for infectious diseases (B) Improvements in sanitation and hygiene (C) Advances in medical care technology (D) Health education
CORRECT ANSWER: (B) Improvements in sanitation and
hygiene
John Snow's path-breaking studies (1848--1854) of the cholera epidemic in London that identified the source as
polluted drinking water from the Thames as well as Edwin Chadwick's role in leading the sanitation movement in Great Britain in the last half of the 19 th century are representative of the importance of improvements in municipal sanitation systems and the promotion of public hygiene. Thomas McKeown and other public health investigators have demonstrated that declines in mortality during the 20 th century occurred before the advent of vaccinations, antibiotics, and other modern medical treatments.
Question 2: According to John Wennberg and colleagues,
small area variations in Medicare expenditures across
geographic areas are primarily attributable to differences in:
(A) Physician practice styles (B) Consumer preferences for high-cost services (C) Age of the population served (D) Health status of the population served
CORRECT ANSWER: (A) Physician practice styles
John Wennberg and other researchers have found wide variations in the rates of various medical care treatments, such as tonsillectomies and hysterectomies, across different areas of the United States. Additional research has shown that these variations are likely not associated with differences in health status, patient age, or consumer preferences, but rather with the practice styles noted in option (A) and with the supply of physicians in different areas. Research on small area variations has contributed to the rationale for the development of clinical practice guidelines.
Question 3: Which of the following statements accurately
describes the financing of health care in the United States?(A) Public health services represent approximately half of the total expenditures for health care (B) Health care expenditures as a percentage of GDP have remained stable within the range of 5%-8% since the 1970s (C) Medicare funds most of the services received by the elderly living in institutional long term care facilities (D) Medicaid is a Federal-State partnership which covers some health care and related services for low-income families
with children and individuals who are elderly, blind and disabled
CORRECT ANSWER: (D) Medicaid is a Federal-State
partnership which covers some health care and related services for low-income families with children and individuals who are elderly, blind and disabled
The percentage of the Gross National Product (GNP) attributable to health care expenditures in the United States for 2008 was approximately 16%. Public health expenditures typically represent less than 3% of total health care expenditures. Medicaid not Medicare is the major source of public funding for institutional long-term care (LTC) for the elderly.
Question 4: Community rating basis for health insurance: (A) Automatically assigns lower rates to subscribers from disadvantaged communities (B) Allows community representatives to negotiate favorable rates
