CPHIMS CPHIMS Clinical Informatics Principles 4 ā Questions and Answers
Question 1: LOINC codes are primarily used in clinical informatics to standardize the representation of:
- Diagnoses and conditions
- Laboratory tests, clinical observations, and clinical document names (Correct answer)
- Drug names and dosages
- Procedure billing codes
Correct answer: Laboratory tests, clinical observations, and clinical document names
LOINC (Logical Observation Identifiers Names and Codes) provides universal codes for labs, clinical measurements, and document types to enable consistent exchange.
Question 2: Which of the following BEST describes the role of a clinical informatics professional during system downtime?
- Suspend all clinical operations until the system is restored
- Ensure downtime procedures are in place, practiced, and support safe patient care (Correct answer)
- Redirect all patients to other facilities
- Immediately restore from the most recent backup without testing
Correct answer: Ensure downtime procedures are in place, practiced, and support safe patient care
Informatics professionals must ensure downtime procedures (paper-based or read-only access) are pre-established and tested so patient care continues safely.
Question 3: The concept of 'minimum necessary' data access in healthcare information systems is MOST directly linked to:
- HIPAA Privacy Rule (Correct answer)
- Meaningful Use Stage 2
- TEFCA exchange framework
- CMS Conditions of Participation
Correct answer: HIPAA Privacy Rule
The HIPAA Privacy Rule establishes that covered entities may only access, use, or disclose the minimum amount of PHI necessary to accomplish the intended purpose.
Question 4: A hospital implements a sepsis alert that triggers when lactate > 2 mmol/L AND systolic BP < 90 mmHg. This type of CDS logic is called:
- Single-parameter threshold alert
- Multi-condition composite rule (Correct answer)
- Passive reference recommendation
- Drug-drug interaction alert
Correct answer: Multi-condition composite rule
Multi-condition composite rules combine multiple clinical parameters using Boolean logic to improve alert specificity and reduce false-positive rates.
Question 5: In clinical informatics governance, the PRIMARY purpose of a clinical informatics committee is to:
- Approve IT infrastructure purchases
- Align health information technology decisions with clinical priorities and safety (Correct answer)
- Conduct HIPAA compliance audits
- Manage vendor contract negotiations
Correct answer: Align health information technology decisions with clinical priorities and safety
Clinical informatics committees bridge clinical and IT leadership to ensure technology decisions are driven by clinical needs, safety goals, and evidence.
Question 6: Which stage of the data-information-knowledge-wisdom (DIKW) hierarchy does a clinical decision support alert represent?
- Data
- Information
- Knowledge (Correct answer)
- Wisdom
Correct answer: Knowledge
CDS alerts encode clinical knowledgeāevidence-based rules derived from synthesized informationāapplied to patient-specific data at the point of care.
Question 7: A patient's medication list shows 'metoprolol' in one system and 'metoprolol succinate 25 mg oral' in another. Reconciling these requires which type of standard?
- SNOMED CT
- RxNorm (Correct answer)
- ICD-10-PCS
- CPT
Correct answer: RxNorm
RxNorm provides normalized names and unique identifiers for clinical drugs, enabling systems to reconcile drug name variations into a single computable representation.
