Question 1

All of the following are common sources of childhood lead exposure today, except:

Accepted Answer

Air from lead in gasoline is no longer a common source of childhood lead exposure today because lead has been removed from gasoline.

Question 2

Which of the following is the most accurate statement about the relationship between lead and nutrition?

Accepted Answer

Low levels of iron and calcium in the diet can increase lead absorption, as the body may absorb more lead when it is deficient in these essential nutrients.

Question 3

Which of the following is an accurate statement about lead toxicity and systems thinking?

Accepted Answer

Lead toxicity is a complex issue influenced by multiple factors, which can interact and amplify the effects. Peeling lead paint can act as a bottleneck, making it difficult to reduce lead exposure.

Question 4

Which of the following is the least accurate statement about the impact of taking a systems-thinking approach to lead exposure?

Accepted Answer

Systems-thinking typically does not identify a single "magic bullet" solution; instead, it involves understanding and addressing multiple interconnected factors and leverage points to effectively manage complex issues like lead exposure.

Question 5

Which of the following is the least accurate description of a role that reductionist thinking plays in systems-thinking?

Accepted Answer

Reductionist thinking typically breaks down complex systems into individual components to understand them, but it is not specifically focused on identifying bottlenecks, which is more aligned with systems-thinking that considers the interactions and interdependencies within the whole system.

Question 6

Which of the following is the least accurate statement about systems-thinking?

Accepted Answer

Systems-thinking often requires making assumptions and may need new data collection, as it involves understanding complex interactions and relationships within a system, which cannot always be captured with existing data alone.

Question 7

Which of the steps in systems-thinking is illustrated in the following example?
The metabolic syndrome, when present, increases the chances of coronary artery disease more than would be expected by adding together the impact of the individual risk factors.

Accepted Answer

The example illustrates how the interaction between multiple risk factors (components of metabolic syndrome) can lead to a greater impact on coronary artery disease than the sum of their individual effects, highlighting the importance of examining interactions.

Question 8

Which of the steps in systems-thinking is illustrated in the following example?
Pregnant women are highly motivated to stop smoking cigarettes, which benefits them as well as reducing the chances of a low-birth-weight child.

Accepted Answer

The answer of Which of the steps in systems-thinking is...

Question 9

Which of the steps in systems-thinking is illustrated in the following example?
The hour after severe trauma is identified as the "golden hour," in which early intervention can have dramatic benefits on the outcome.

Accepted Answer

The answer of Which of the steps in systems-thinking is...

Question 10

Which of the steps in systems-thinking is illustrated in the following example?
The patient safety movement found that relying exclusively on malpractice to address safety reduced the options for addressing safety issues. Once additional options were provided, the process worked far more effectively.

Accepted Answer

The answer of Which of the steps in systems-thinking is...

Question 11

Which of the steps in systems-thinking is illustrated in the following example?
Efforts to control the opioid epidemic found that reducing the number of pills in opioid prescriptions in Emergency Departments had an impact far beyond expectations on the subsequent addiction to opioids.

Accepted Answer

The example illustrates identifying leverage points, as reducing the number of pills in prescriptions had a significant and unexpected impact on addiction rates, showing a point where small changes can lead to significant effects.

Question 12

Which of the approaches to systems-doing is illustrated in the following example?
A disaster management plan designed to meet shared goals is organized by the central government agency that has a lead role in obtaining data and directing implementation of the plan.

Accepted Answer

The answer of Which of the approaches to systems-doing is...

Question 13

Which of the approaches to systems-doing is illustrated in the following example?
Motor vehicle injuries and death have been dramatically reduced due to public and private organizations working separately toward a common goal.

Accepted Answer

Parallel play refers to different organizations working independently towards a common goal without direct interaction or coordination.

Question 14

Which of the approaches to systems-doing is illustrated in the following example?
Lead exposure has been reduced and efforts have been made to respond to high levels of blood lead through the work of multiple agencies that share common goals and information, but separately implement their roles.

Accepted Answer

The answer of Which of the approaches to systems-doing is...
