A CDS alert fires 400 times per month but 92% are overridden by clinicians. This phenomenon is called:

Answer: Alert fatigue

Alert fatigue occurs when clinicians are overwhelmed by excessive, low-specificity alerts and begin routinely overriding them without adequate evaluation, including clinically significant alerts.

Which level of informatics competency is expected of ALL nurses regardless of specialization?

Answer: Basic computer and information literacy including EHR documentation and data retrieval

All nurses are expected to have foundational informatics competencies: basic computer literacy, EHR use for documentation, retrieval of patient data, and use of electronic resources to support patient care.

Which principle of human factors engineering is most important when designing a medication reconciliation workflow in the EHR to prevent medication errors?

Answer: Designing systems that make it easy to do the right thing and difficult to make an error using forcing functions and error proofing

Human factors engineering aims to design systems that align with human cognitive capabilities, use forcing functions to prevent errors, and reduce reliance on memory.

Which of the following best describes interoperability in health information technology?

Answer: The ability of different health information systems to exchange and use clinical data seamlessly

Interoperability refers to the ability of different health information systems, devices, and applications to access, exchange, integrate, and cooperatively use data in a coordinated manner.

Which usability testing method involves observing nurses performing real tasks in the EHR and measuring time-on-task, errors, and satisfaction?

Answer: Summative usability testing with task-based performance metrics

Summative usability testing measures actual performance outcomes (task completion rates, time-on-task, error rates, satisfaction scores) with representative users performing realistic tasks. It quantifies usability for go/no-go decisions.

Under HIPAA, which represents a permitted use of PHI without requiring patient authorization?

Answer: Disclosing PHI to another treating provider for care coordination (treatment purpose)
