Two most typical examples of prospective research in medicine are: Case-control studies and Observational studies Cohort studies and Experimental studies Cross-sectional studies and Qualitative studies 27. Using a national US database, rates of lung cancer were determined among New Yorkers, Texans and Californians. Lung cancer prevalence was 25% in New York, 30% in Texas and 20% in California.

If all persons with deficiencies in pancreatic insulin production have symptoms of type I diabetes, and these persons are from the general population (i.e., they were not included in the study sample because of other deficiencies that could cause these symptoms), one can conclude that all persons with deficiencies in pancreatic insulin production have symptoms of type I diabetes. The explanation is according to: Deduction (deducting modes of inference) Induction (inducting modes of inference) Abduction (abducting modes of inference) Coherence (coherence modes of inference) 71.

The pragmatic theory of truth argues: It is circular when truth depends on what works, and researchers’ assessment of what works depends on their conception of what is true Something is true if it corresponds to some truth maker things in the world A scientific hypothesis or theory is true if it coheres with other hypotheses or theories. If it is completely out of the realm of established knowledge, it is most likely untrue 73. The correspondence theory of truth argues: It is circular when truth depends on what works, and researchers’ assessment of what works depends on their conception of what is true Something is true if it corresponds to some truth maker things in the world A scientific hypothesis or theory is true if it coheres with other hypotheses or theories. If it is completely out of the realm of established knowledge, it is most likely untrue 74.

Three areas in which researchers and institutional review boards should apply ethical principles: (one is incorrect) They maintain high commercial standard The informed consent process The assessment of risk and benefit The selection of human subjects 93.

Which one of four principles of the Nuremberg’s code provided to you is formulated incorrectly? The voluntary consent of the human subjects is absolutely essential The experiment shouldn’t be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and random and unnecessary in nature The experiment should be so designed and based on the results of animal experimentation and knowledge of the natural history of the disease or other problem under study that the anticipated results will justify the performance of the experiment No experiment should be conducted where there is a prior reason to believe that death or disabling injury will occur; except in those experiments where the experimental physicians also serve as subjects. 96.

Points to Keep in Mind When Choosing a Research Problem (choose incorrect answer) Select biological problems that apply to organisms, organs, or cells in vivo. Don’t stay away from research questions that have emerged primarily from in vitro studies, unless those questions clearly apply to in vivo situations as well.
