Epidemiology Test Questions and Answers PDF Questions
Question 1 of 5
Which manifestation would the nurse include when teaching about mild to moderate food poisoning at a community health fair?
Correct Answer: C
Rationale: The correct answer is C: Dehydration. Mild to moderate food poisoning commonly leads to dehydration due to fluid loss from vomiting and diarrhea. Dehydration is a key concern as it can lead to serious complications. Incorrect choices: A: Bloody diarrhea is more indicative of severe food poisoning or infections like E. coli. B: Diarrhea lasting more than 3 days suggests a more severe case or underlying condition. D: Fever less than 102°F is not specific to food poisoning and can occur in various illnesses.
Question 2 of 5
A community health clinic put a tax levy on the ballot. An angry man asks a nurse, 'How can you ask me to pay taxes to buy immunizations for parents who do not want to pay for their kids to get their shots?' Which is the most appropriate response by the nurse?
Correct Answer: C
Rationale: Herd immunity is a state in which those not immune to an infectious agent will be protected if a certain proportion (generally considered to be $80 \%$ ) of the population has been vaccinated or is otherwise immune. If most persons are immune, it will be difficult for an infectious disease to spread.
Question 3 of 5
A community health nurse determined exactly how many cases of a particular disease were currently occurring in the community. Which action should the nurse take before determining what interventions should be planned?
Correct Answer: B
Rationale: No conclusions can really be drawn from just knowing a number. Only by converting that count to a rate and then comparing the rate with the previous rate, or with the rate in the broader environment or a similar community nearby, can any conclusions be drawn as to whether there is a problem or intervention needed. Once the rate has been calculated, the nurse will be able to share the findings with leadership, determine the resources available to intervene if necessary, and determine if the disease is a priority.
Question 4 of 5
Which is the most effective way to determine if Healthy People 2020 is improving the health of Americans?
Correct Answer: B
Rationale: Effectiveness of Healthy People 2020 depends on the availability of reliable baseline and continuing data to characterize health problems and evaluate goal achievement. Surveillance is crucial. Without surveillance data, there is no relatable data available. Increased financing will not assist in determining if the health of Americans is improving. Although it is important for individuals to be willing to share health information so that data collection can be completed, individual health information alone will not be an effective determinant of the health of Americans.
Question 5 of 5
What are focus areas of nutritional epidemiology?
Correct Answer: C
Rationale: Nutritional epidemiology studies the relationship between diet and health outcomes in populations. Choice A addresses the role of nutritional factors in disease causation (e.g., linking high fat intake to heart disease), a core focus. Choice B addresses how dietary changes can improve health (e.g., increasing fiber to reduce colon cancer risk), also a key area. Since both are accurate and central to the field, C is correct. D is incorrect as both A and B are valid.
