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 emphasizes the complexity of disease causation by considering multiple interacting factors. It recognizes that diseases result from a web of interconnected factors rather than a simple cause-effect relationship. The nurse would most likely use this model to understand the intricate relationships between biological, social, and environmental factors contributing to disease. Option A: "Which of the following models would the nurse most likely use?" is not a model itself but a question, so it is not a valid choice. Option B: Epidemiologic triangle focuses on the host, agent, and environment as the three key factors contributing to disease causation, which is a simpler model than the web of causality. Option C: Health promotion is a strategy to prevent disease rather than a model that explains the multifactorial nature of disease causation.
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: They are close friends. The key to this question lies in the fact that the two women agree on almost everything and have similar preferences. Close friends often share common interests, influencing each other's choices and preferences over time. This close bond creates a strong sense of connection and understanding, leading to agreement on various topics. Choices A, C, and D are incorrect because membership in the same birth cohort, attending the same school, or going to the same church do not inherently explain the similarity in preferences and agreement between the two women as well as the close friendship does.
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. The rationale for this is that by only surveying high school students who meet for various school organizations, the sample is not representative of the entire high school population. This can lead to skewed results and an inaccurate representation of drug use among all high school students. A: Classification bias refers to errors in the classification of study subjects. This is not applicable in this scenario. B: Confounding bias occurs when an extraneous variable is associated with both the exposure and the outcome. This is not relevant to the method of data collection proposed. C: Personal bias involves the researcher's own subjective beliefs influencing the study. This is not directly related to the method of data collection being discussed. In summary, choice D is the correct answer because using surveys only with students who are part of school organizations introduces selection bias, leading to an unrepresentative sample and potentially inaccurate results.
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: Rationale: B: Health problems for which the specific population is at risk - This variable is crucial in determining the screenings to include as it helps the nurse focus on addressing the most relevant health concerns for the population. Summary of Incorrect Choices: A: Adequate space for persons to lie down after testing until side effects are reduced - While important for safety, this is not directly related to determining which screenings to include. C: Whether adequate privacy can be obtained for the invasive or embarrassing procedures - Privacy is important but does not directly impact the choice of screenings. D: Whether health care providers are available to follow up on any positive screening results - Follow-up care is essential but does not guide the selection of screenings.
Question 5 of 5
Which description of disease activity in a single area corresponds to endemic levels of disease?
Correct Answer: A
Rationale: The correct answer is A because endemic disease refers to the constant presence or usual prevalence of a disease in a specific geographic area. Choice A describes a consistent number of cases each week, which aligns with the definition of endemic disease. Choices B, C, and D all indicate fluctuations in the number of cases that do not reflect a stable endemic level. Choice B suggests a very low usual prevalence, choice C shows a sudden spike in cases, and choice D indicates a significant increase from the usual worldwide cases, none of which are characteristic of endemic disease.
