Which standardized terminology is primarily used to encode nursing diagnoses in electronic health records?
Answer: NANDA International
NANDA International (formerly North American Nursing Diagnosis Association) maintains the standardized taxonomy of nursing diagnoses used in clinical documentation.
In Meaningful Use Stage 2 (now Promoting Interoperability), which requirement specifically addressed sharing care summaries during transitions?
Answer: Transmit Summary of Care record
The 'Transmit Summary of Care' objective required eligible professionals to electronically transmit a care summary for a percentage of care transitions and referrals.
A clinical informaticist is designing a dashboard for a cardiac care unit. Applying Gestalt principles, grouping related vital signs visually in the same panel uses which principle?
Answer: Proximity
The Gestalt principle of proximity states that elements placed close together are perceived as related, aiding rapid visual grouping in dashboards.
Which database model is most appropriate for storing and querying highly connected clinical data, such as drug-drug interaction networks?
Answer: Graph database
Graph databases natively represent entities and their relationships as nodes and edges, making traversal of complex interaction networks highly efficient.
Under the ICD-10-PCS coding system, the root operation 'Excision' differs from 'Resection' in that:
Answer: Excision removes a portion of a body part; Resection removes the entire body part
ICD-10-PCS defines Excision as cutting out a portion of a body part and Resection as cutting out all of a body part without replacement.
A health system's risk stratification model assigns high-risk scores to patients most likely to benefit from care management. The primary goal of this stratification is:
Answer: Targeting limited care management resources to highest-need patients
Risk stratification directs scarce care management resources (RN case managers, social workers) toward patients with the greatest likelihood of high utilization or adverse outcomes.
In a clinical data warehouse, a 'slowly changing dimension' (SCD) Type 2 strategy handles changes to a patient's home address by:
Answer: Adding a new row with an effective date range while preserving the historical record
SCD Type 2 preserves full history by inserting a new dimension row with effective start/end dates, enabling point-in-time reporting without losing prior values.
