111)
1. All of the following statements regarding practice guidelines set forth by governing
x x x x x x x x x x x




agencies and professional organizations are true EXCEPT:
x x x x x x x




A. Clinical practice guidelines protect caregivers against inappropriate charges of
x x x x x x x x




xmalpractice, yet do not provide protection for patients from receiving substandard care.
x x x x x x x x x x x




B. Practice guidelines have largely reached a stage of nuance allowing them to address
x x x x x x x x x x x x




every unique illness and patient presented to the modern physician.
x x x x x x x x x x




C. Practice guidelines provide a legal constraint to physicians, and deviation from
x x x x x x x x x x




guideline-based care invariably leaves physicians vulnerable to legal action.
x x x x x x x x x




D. Where different organizations disagree regarding practice guidelines, a third- party
x x x x x x x x x




x agency has been appointed to mitigate these disagreements such that now all major
x x x x x x x x x x x x




xorganizations' guidelines are consistent. x x x




E. All of the above statements are not true.
x x x x x x x




Answer: E x




Explanation: Practice guidelines cannot address every unique patient presentation,
x x x x x x x x




x discrepancies exist between major organizations, and while they provide guidance,
x x x x x x x x x

,they do not create rigid legal constraints. Guidelines protect both clinicians and
x x x x x x x x x x x




xpatients, though they cannot account for every clinical nuance.
x x x x x x x x




2. Regarding molecular medicine, which of the following statements represents an
x x x x x x x x x




INACCURATE example of the listed area of study:
x x x x x x x x




A. Exposomics: An endocrinologist studies sunlight exposure and population risk of hip
x x x x x x x x x x




xfracture.
B. Metabolomics: A biochemist studies the rate of flux through the creatine kinase
x x x x x x x x x x x




xpathway during the cardiac cycle.
x x x x




C. Metagenomics: A biologist studies the genomic alterations in molds commonly x x x x x x x x x




xfound in human dwellings.
x x x




D. Microbiomics: A microbiologist studies the genomic variation in thermophiles,
x x x x x x x x




x bacteria that can survive extreme heat near deep ocean vents.
x x x x x x x x x




E. Proteomics: A cardiologist studies desmosomal proteins and their
x x x x x x x




xposttranslational modifications in studying arrhythmogenic right ventricular
x x x x x x




x dysplasia.

Answer: D x




Explanation: Microbiomics is the study of resident microbes in humans and other
x x x x x x x x x x x




mammals. Thermophiles do not reside in humans or other mammals by definition, so their
x x x x x x x x x x x x x




xstudy would not be included in microbiomics.
x x x x x x




3. Which of the following is the best definition of evidence-based medicine?
x x x x x x x x x x




A. A summary of existing data from existing clinical trials with a critical methodologic
x x x x x x x x x x x x




review and statistical analysis of summative data
x x x x x x x




B. A type of research that compares the results of one approach to treating disease with
x x x x x x x x x x x x x x




another approach to treating the same disease
x x x x x x x




C. Clinical decision-making support tools developed by professional organizations that
x x x x x x x x




include expert opinions and data from clinical trials
x x x x x x x x




D. Clinical decision making supported by data, preferably randomized controlled clinical
x x x x x x x x x




xtrials

, E. One physician's clinical experience in caring for multiple patients with a specific disorder
x x x x x x x x x x x x




xover many years
x x




Answer: D x




Explanation: Evidence-based medicine refers to clinical decisions supported by data, with
x x x x x x x x x x




the strongest evidence from randomized controlled trials. Option A
x x x x x x x x x




describes systematic reviews, B describes comparative effectiveness research, and E
x x x x x x x x x




xdescribes anecdotal evidence. x x




4. Which of the following is the standard measure for determining the impact of a health
x x x x x x x x x x x x x x




condition on a population?
x x x x




A. Disability-adjusted x x life-years
B. Infant mortality x




C. Life expectancy x




D. Standardized mortality ratio x x




E. Years of life lost x x x




Answer: A x




Explanation: Disability-adjusted life-years (DALY) is the standard WHO measure
x x x x x x x x




xaccounting for both years of life lost due to premature death and productive years lost
x x x x x x x x x x x x x x




xdue to disability.
x x




5. Which of the following statements regarding disease patterns worldwide is true?
x x x x x x x x x x




A. Childhood undernutrition is the leading risk factor for global disease burden.
x x x x x x x x x x




B. In a 2006 publication, the World Health Organization (WHO) estimated that 10% of the
x x x x x x x x x x x x x




xtotal global burden of disease was due to modifiable environmental risk
x x x x x x x x x x



factors.
C. In 2010, ischemic heart disease was the leading cause of death among adults.
x x x x x x x x x x x x




D. In the last two decades, mortality attributed to communicable diseases, maternal and
x x x x x x x x x x x




perinatal conditions, and nutritional deficiencies has remained fairly stable.
