Question 1

Which of the following features of a systems-thinking approach is best illustrated by this statement?
The combination of high levels of radon exposure and cigarette smoking has been found to multiply the incidence of lung cancer.

Accepted Answer

The statement illustrates how systems-thinking focuses on the interconnections and interactions between health problems, as it highlights the combined effect of radon exposure and cigarette smoking on lung cancer incidence.

Question 2

Which of the following features of a systems-thinking approach is best illustrated by this statement?
Recent reductions in cigarette smoking in the United States have led to a new focus on addiction to nicotine.

Accepted Answer

C

Question 3

Which of the following features of a systems-thinking approach is best illustrated by this statement?
Early pregnancy has been found to be an effective time to provide intensive smoking cessation services.

Accepted Answer

The statement highlights the identification of early pregnancy as a leverage point where smoking cessation interventions can have a substantial impact, which is a key feature of systems-thinking.

Question 4

Which of the following is NOT true of a systems-thinking approach?

Accepted Answer

Systems-thinking does not attempt to reduce problems to one factor at a time; instead, it considers the complexity and interconnections within systems.

Question 5

Delays in getting to health care after a severe injury greatly reduce the likelihood of a good outcome even with the best health care. This can best be described as which of the following?

Accepted Answer

A bottleneck refers to a point of congestion or blockage that slows or limits the flow of a process, in this case, the delay in accessing health care after an injury.

Question 6

Which of the following is the most accurate statement about patient safety?

Accepted Answer

The focus on "near misses" in patient safety allows healthcare systems to identify and address potential errors before they cause harm, improving overall safety.

Question 7

Which of the following is the most accurate statement about the microbiological influences component of One Health?

Accepted Answer

RNA viruses have a higher mutation rate than DNA viruses due to the lack of proofreading mechanisms during replication, making them more prone to mutations.

Question 8

Which is the most accurate statement about the ecosystem health component of One Health?

Accepted Answer

Climate change can alter ecosystems, expanding the range of disease vectors like mosquitoes, which can increase the transmission of diseases to humans.

Question 9

Which of the following is the most accurate statement about the human-animal interactions component of One Health?

Accepted Answer

Exotic pets can carry zoonotic diseases that are less well-known and potentially more dangerous than those from common pets like dogs and cats.

Question 10

Which of the following statements is the most accurate statement about systems-doing?

Accepted Answer

Collaboration in systems-doing involves coordinated planning and selective sharing of information to effectively address complex issues in population health.

Question 11

Which of the ideal criteria for a successful screening program is satisfied by the following statement?
PAP smears are safe and widely sought after by women, especially when they are covered by health insurance.

Accepted Answer

The statement highlights that PAP smears are safe, widely accepted, and often covered by insurance, indicating that the screening is acceptable in terms of costs, harms, and patient acceptance.

Question 12

Which one of the following diseases is the least likely to be eradicated?

Accepted Answer

Influenza is the least likely to be eradicated due to its high mutation rate and the existence of multiple strains, making it difficult to develop a universal vaccine.

Question 13

Which of the following is the most accurate statement about vaccines?

Accepted Answer

Live attenuated vaccines can stimulate both cellular (intracellular) and humoral (antibody-related) immune responses, making them effective in providing comprehensive immunity.
