Epidemiology Questions Questions
Question 1 of 5
A nurse is examining the various factors that lead to disease and suggests several areas where
Correct Answer: D
Rationale: The correct answer is D: Web of causality. This model considers multiple factors interacting and contributing to disease causation. It emphasizes the complexity and interconnectedness of various determinants of health. The epidemiologic triangle (B) focuses on agent, host, and environment in disease transmission, not causation. Health promotion (C) involves strategies to improve health behaviors and outcomes, not disease causation. In summary, the Web of causality model is the most appropriate choice as it comprehensively examines the multifactorial nature of disease etiology.
Question 2 of 5
Two women seem to agree on almost everything from favorite music to favorite media stars to the best way to prepare a meal. Which of the following best explains this similarity in the two women?
Correct Answer: B
Rationale: The correct answer is B because the similarity in opinions and preferences between the two women suggests a close friendship. Close friends often share common interests and values, leading to agreement on various topics. Choice A is incorrect because birth cohort does not necessarily determine shared preferences. Choice C is incorrect as attending the same school does not guarantee similar tastes. Choice D is incorrect as sharing the same church does not explain agreement on non-religious topics.
Question 3 of 5
A teacher recommends that surveys to obtain data on drug use be given to high school students when they meet for various school organizations. Which of the following best describes why the nurse would reject this suggestion?
Correct Answer: D
Rationale: The correct answer is D: This method of data collection would result in selection bias. By administering surveys only to students who are part of school organizations, the sample is not representative of the entire student population, leading to selection bias. This bias can skew the results and make them less generalizable. A: Classification bias is when participants are inaccurately categorized, not relevant in this context. B: Confounding bias occurs when an external factor influences the relationship between the variables being studied, not applicable here. C: Personal bias involves individual opinions affecting the results, which is not the issue with this method of data collection.
Question 4 of 5
A nurse is planning to host a health screening at a large urban mall. Which of the following variables will help the nurse determine which screenings should be included? (Select all that apply.)
Correct Answer: B
Rationale: Step-by-step rationale for why choice B is correct: 1. The nurse needs to consider health problems specific to the population to prioritize screenings. 2. Screening for health problems the population is at risk for will be more relevant and beneficial. 3. Including these screenings will address the specific health needs of the community, making the event more impactful. 4. This variable ensures that the screenings provided are tailored to the population's needs. Summary of why the other choices are incorrect: A. Adequate space for resting is important but not a variable that directly determines which screenings to include. C. Privacy considerations are important but do not directly impact the choice of screenings. D. Availability of follow-up care is crucial but does not guide the selection of screenings to include.
Question 5 of 5
Which description of disease activity in a single area corresponds to endemic levels of disease?
Correct Answer: A
Rationale: Rationale for Correct Answer A: - Endemic levels refer to consistent, expected rates of disease in a specific area. - Choice A states there are usually 20-30 cases each week, consistent with endemic levels. - The fact that there were 29 cases this past week aligns with the usual range, indicating endemicity. - This means the disease is consistently present in that area without significant spikes or drops. Summary of Incorrect Choices: - Choice B: The usual rate in this choice is much lower than endemic levels, making it unlikely to be endemic. - Choice C: The usual rate is exceeded significantly in the past week, indicating an outbreak rather than endemicity. - Choice D: The global scale mentioned is not relevant to determining endemic levels in a single area.
