CPHIMS CPHIMS Clinical Informatics Principles 3

Question 1

The primary goal of computerized physician order entry (CPOE) in clinical settings is to:

Accepted Answer

Reduce medication errors caused by illegible handwriting and transcription

Answer

CPOE eliminates handwritten orders, reducing transcription errors and enabling real-time CDS checks at the point of ordering.

Question 2

Which data standard is MOST commonly used to encode diagnoses for billing and epidemiological reporting in the United States?

Accepted Answer

ICD-10-CM

Answer

ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the US standard for coding diagnoses on claims and public health reports.

Question 3

In clinical informatics, 'interoperability' at the semantic level means that:

Accepted Answer

The shared meaning of data is preserved across different systems

Answer

Semantic interoperability ensures that the meaning of clinical data—not just its format—is consistently understood by both the sending and receiving system.

Question 4

A clinical informaticist is asked to evaluate why nurses skip structured data fields and free-text their assessments. The MOST appropriate first step is:

Accepted Answer

Observe nurses in their workflow to understand the root cause

Answer

Observing clinicians in real workflows (contextual inquiry) reveals true barriers to structured documentation that surveys or audits may miss.

Question 5

FHIR (Fast Healthcare Interoperability Resources) differs from HL7 v2 primarily because FHIR:

Accepted Answer

Is based on modern web standards like REST and JSON/XML

Answer

FHIR leverages RESTful APIs, JSON, and XML—making it easier to implement with modern web and mobile development tools than legacy HL7 v2.
