Question 1

A hospital's EHR uses a master patient index (MPI). Which scenario MOST directly threatens MPI integrity?

Accepted Answer

A registration clerk creates a duplicate record for a returning patient

Answer

Duplicate patient records created during registration are the primary threat to MPI integrity, potentially causing care fragmentation and safety risks.

Question 2

Under the ONC's Trusted Exchange Framework and Common Agreement (TEFCA), what is the role of a Qualified Health Information Network (QHIN)?

Accepted Answer

Serving as a nationwide network operator enabling interoperability between networks

Answer

QHINs are designated network operators under TEFCA that connect health information networks to enable nationwide health data exchange.

Question 3

A CDI specialist reviews a CAC system's output and finds that a post-operative wound infection present on admission (POA) is being suggested without a POA indicator. What is the MOST likely consequence if this error reaches final billing?

Accepted Answer

The condition may be misclassified as a hospital-acquired condition, triggering a payment penalty

Answer

Without the correct POA indicator, a condition present before admission can be flagged as hospital-acquired, resulting in a HAC payment reduction under Medicare.

Question 4

Which component of a data warehouse architecture is responsible for cleansing, transforming, and loading data from source EHR systems before it reaches the analytical repository?

Accepted Answer

Extract, Transform, Load (ETL) process

Answer

The ETL process extracts raw data from source systems, transforms it to a consistent format, and loads it into the data warehouse for analysis.
