Introduction to Epidemiology Case Study Questions Questions
Question 1 of 5
Public health surveillance can be described primarily as which of the following actions?
Correct Answer: A
Rationale: The correct answer is A because public health surveillance involves monitoring occurrences of public health problems to understand patterns, trends, and risk factors. It helps in detecting outbreaks, planning interventions, and evaluating the effectiveness of public health programs. Choice B is incorrect as it refers to the response to surveillance findings, not surveillance itself. Choice C is incorrect as surveillance involves systematic data collection rather than gathering information from community members. Choice D is incorrect as it pertains to contact tracing, which is a specific activity within outbreak investigation, not surveillance.
Question 2 of 5
Which surveillance system would the CDC utilize to track and investigate foodborne illnesses?
Correct Answer: A
Rationale: The correct answer is A: System for Enteric Disease Response, Investigation, and Coordination (SEDRI). The CDC would utilize SEDRI for tracking and investigating foodborne illnesses because it is specifically designed for managing enteric diseases like foodborne illnesses. SEDRI allows for prompt response, coordination, and investigation of outbreaks, helping the CDC to effectively monitor and control the spread of foodborne illnesses. Choice B is incorrect because it is not a specific surveillance system related to enteric diseases. Choice C, the National Notifiable Disease Surveillance System (NNDSS), focuses on a broader range of notifiable diseases and may not be as specialized for foodborne illnesses as SEDRI. Choice D, the Global Outbreak Alert and Response Network (GOARN), is more focused on global outbreaks rather than specific surveillance for foodborne illnesses within the US.
Question 3 of 5
A nurse is employed as a nurse epidemiologist. Which of the following activities would most likely be completed by the nurse?
Correct Answer: B
Rationale: The correct answer is B: Evaluating the number of clients presenting with similar diseases. As a nurse epidemiologist, the nurse's main role is to analyze and interpret data related to disease patterns in populations. By evaluating the number of clients with similar diseases, the nurse can identify trends, risk factors, and potential outbreaks. This activity helps in disease surveillance and prevention efforts. Explanation for other choices: A: Eliciting health history - This task is more aligned with a clinical nurse's role in assessing individual patients, not with an epidemiologist's population-level focus. C: Performing a physical examination - Similar to eliciting health history, physical examinations are more related to individual patient care rather than population-based analysis. D: C M - Incorrect choice.
Question 4 of 5
Between 2010 and 2015, 1000 of 10,000 young women age 17 to 20 years at a university tested positive for a sexually transmitted infection (STI). Of the 1000 diagnosed STIs, 300
Correct Answer: A
Rationale: Rationale: 1. Statement A summarizes the findings by highlighting the key information about the STI prevalence among young women at the university. 2. It accurately presents the data - 1000 out of 10,000 young women tested positive for an STI, providing a clear summary of the situation. 3. It focuses on the main point of the data, which is the prevalence of STIs among the specified group. 4. Option B talks about the proportion of gonorrhea cases, which is not the main focus of the question. Options C and D are incomplete and do not provide a clear summary of the findings.
Question 5 of 5
This year 600 of 8000 young women age 17 to 20 years at a university health center tested positive for a sexually transmitted infection (STI). Which of the following terms best describes this data?
Correct Answer: C
Rationale: The correct answer is C: Prevalence. Prevalence refers to the proportion of individuals in a population with a specific condition at a given point in time. In this case, the percentage of young women with STI is a measure of prevalence, as it represents the existing cases within the population. It does not indicate the rate of new cases (incidence), the spread of a disease throughout a population (epidemic), or the likelihood of developing a disease (risk). Prevalence captures the burden of the disease in the population at a specific time point.
