Complete Test Bank Tietz Fundamentals of Clinical Chemistry and Molecular Diagnostics 7th Edition Burtis Questions & Answers with rationales-1. An individual working in a clinical chemistry laboratory... is married to a sales representative who works for a company that sells chemistry laboratory supplies. When the laboratory manager requests a list of needed supplies, cost of supplies, and vendors, this individual only recommends the spouse’s company as the vendor. This is considered to be a(n): a. accounting issue. b. possible conflict of interest. c. maintenance of confidentiality issue. d. problem with resource allocation. ANS: B Concern has been raised over the interrelationships between practitioners in the medical field and commercial suppliers of drugs, devices, equipment, etc., to the medical profession. Similarly, relationships have been scrutinized between clinical laboratorians and manufacturers and providers of diagnostic equipment and supplies. These concerns led the National Institutes of Health (NIH) in 1995 to require official institutional review of financial disclosure by researchers and management of situations in which disclosure indicates potential conflicts of interest.

A friend of the patient claims that the same painkiller “worked wonders” to reduce her pain after the same surgery. The physician states that the difference in the effect of the drug might be caused by , which is studied in pharmacogenetics. a. epidemiology b. an inherited disease c. a conflict of interest d. a genetic variation in drug-metabolizing enzymes ANS: D Pharmacogenetics is the study of the genetic variation of drug metabolism between individuals. DIF: 1 REF: Page 3 OBJ: 1 3. John works in a molecular diagnostics laboratory and receives a blood sample that has the name of a close friend printed on the bar-coded label. The genetic test that is ordered on the friend’s sample would provide diagnostic information about a disorder that has a poor prognosis, and the test is usually performed by John. He asks a fellow employee to analyze the sample for him and not divulge the results. This ethical issue concerns: a. confidentiality of patient genetic and medical information. b. a conflict of interest. c. resource allocation. d. diagnostic accuracy. ANS: A Clinical laboratorians have long been responsible for maintaining the confidentiality of all laboratory results, a situation made even more critical with the advent of increasingly powerful genetic testing. DIF: 1 REF: Page 4 OBJ: 6 | 7 4. Molecular diagnostic testing methods and results can be: a. qualitative only. b. quantitative only. c. either qualitative or quantitative. ANS: C Molecular diagnostic methods can be either qualitative or quantitative in nature, depending on the clinical need. DIF: 1 REF: Page 3 [Show More]
