NR 503-MIDTERM EXAM QUESTIONS WITH VERIFIED RATIONALES LATEST 2024 ALREADY GRADED A+ 1.Types of Causation – ANS1) Necessary-disease only occurs is disease is present -Sufficient-Exposure always leads to disease -Necessary BUT not sufficient: factors happen in a temporal sequence. -Sufficient BUT not necessary: A specific factor can cause a disease process, but other factors can cause the same disease. -Neither sufficient NOR necessary: Specific factor can becombined with other factors to produce a disease 2. ways to establish causation – ANS- Temporal relationship-associated factor must be present before the disease Strength of association-The stronger the relationship, the more likely it is casual -Dose-response relationship-dose increases, so does the risk of development of the disease -replication of findings-findings can be found repeated in other studies -Biological plausibility-current knowledge on the factor or exposure and the response of the human body on the cellular level is consistent with the findings 3. Absolute Risk – ANS-Incidence of a disease in a population 4. Active Surveillance – ANS-Case by case basis Each specific person's information is entered into a database. 5. Aggregate – ANS-defined population 6. Analytic Study Methods – ANS-Consists of observational and experimental Case control and cohort 7.Attributable risk – ANS-how much of the risk (incidence) of the disease we hope to prevent if able to eliminate exposure to the agent in question 8.Best way to establish causation – ANS-Observation of humans who have a trait,
