Question 1

What is the primary purpose of a Clinical Decision Support System (CDSS) in nursing informatics?

Accepted Answer

To provide evidence-based alerts and recommendations at the point of care

Answer

CDSS provides evidence-based alerts and recommendations to clinicians at the point of care to improve patient safety and outcomes.

Question 2

Which type of CDSS alert fires when a prescribed medication exceeds a safe dosage threshold?

Accepted Answer

Dose range checking alert

Answer

Dose range checking alerts notify clinicians when an ordered dose falls outside the safe high or low limits for that drug.

Question 3

Alert fatigue in CDSS occurs most commonly when:

Accepted Answer

Too many low-priority alerts fire, causing clinicians to override them without review

Answer

Alert fatigue results from an excessive volume of low-priority alerts, leading clinicians to override or ignore them reflexively.

Question 4

An informatics nurse is evaluating CDSS effectiveness. Which metric BEST measures appropriate alert response?

Accepted Answer

Alert override rate

Answer

The alert override rate indicates how often clinicians bypass alerts, helping identify whether alerts are acted upon appropriately.

Question 5

Accepted Answer

Reference information accessible within the EHR workflow

Answer

Passive CDSS tools, such as embedded reference information, provide guidance only when the clinician actively seeks it rather than interrupting workflow.
