Accepted Answer

Basic computer and information literacy including EHR documentation and data retrieval

Answer

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

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

Answer

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.

Question 5

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

Accepted Answer

Summative usability testing with task-based performance metrics

Answer

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.
