Question 5

An informatics team is analyzing EHR data to identify patients at high risk for sepsis. By developing and applying a predictive algorithm that combines vital signs, lab results, and patient history, the team is primarily focused on which core principle of clinical informatics?

Accepted Answer

Transforming data into actionable knowledge to improve patient safety.

Answer

Ensuring data standardization through terminology mapping.

Answer

Facilitating enterprise-wide system interoperability.

Answer

Managing the lifecycle of health information technology.

Question 6

During a system implementation, an informaticist observes that clinicians are frustrated because alerts are firing too frequently and are often not relevant to the specific patient context, leading them to ignore the warnings. This phenomenon is best described as:

Accepted Answer

Alert fatigue

Answer

Semantic interoperability failure

Answer

Scope creep

Answer

System downtime
