Epidemiology Questions Questions
Question 1 of 5
Public health surveillance is only conducted by public health agencies.
Correct Answer: B
Rationale: Other entities like hospitals also perform surveillance.
Question 2 of 5
Which of the following actions by Florence Nightingale demonstrates her role as an epidemiologist?
Correct Answer: B
Rationale: The correct answer is B because Florence Nightingale demonstrated her role as an epidemiologist by showing that a safer environment led to decreased mortality rates. She implemented measures such as improving sanitation, ventilation, and hygiene in hospitals during the Crimean War, resulting in a significant reduction in deaths. This exemplifies her understanding of how environmental factors impact public health outcomes. Choice A is incorrect because convincing others to provide nursing care does not directly relate to epidemiology. Choice D is incorrect as addressing water, food supplies, lice, and rats pertains more to public health and sanitation practices rather than epidemiology. Choice C is left blank as it does not provide any relevant information.
Question 3 of 5
young women had the problem. The answer of 300:1300 adds the total of the numerator to the denominator, which is unnecessary because the gonorrhea cases were already included in the denominator. In the answer of 300:500, the ratio comparing gonorrhea to chlamydia does not meet the epidemiological definition of proportion
Correct Answer: A
Rationale: The correct answer is A because in epidemiology, a proportion is a ratio where the denominator must contain the numerator. In this case, the denominator should include all STIs, not just gonorrhea cases. The answer of 50% reflects gonorrhea cases to all STIs, not the total STI problem. Therefore, it does not summarize the overall STI burden accurately. The other choices do not adhere to the fundamental principle of epidemiological proportions and fail to provide a comprehensive assessment of the situation.
Question 4 of 5
A nursing staff has successfully screened for diabetes in the community. Which of the following might best persuade the health board to increase funding for diabetic clinics in this community?
Correct Answer: A
Rationale: The correct answer is A because it presents a compelling argument for increased funding by highlighting the urgency of addressing the diabetes issue as an epidemic. This term emphasizes the seriousness and widespread nature of the problem, which is likely to grab the attention of the health board. Choices B, C, and D all mention an increase in diabetes incidence or prevalence, but they lack the sense of urgency and gravity conveyed by the term 'epidemic.' B does not provide a strong enough reason for increased funding, while C and D focus solely on the statistical aspect without emphasizing the significance of the situation. In summary, A effectively communicates the urgent need for action, making it the most persuasive choice for securing additional funding.
Question 5 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.
