WGU D220 STUDY GUIDE 2026
COMPREHENSIVE ANSWER DIGEST
◉1. What is a patient safety benefit of a pharmacy information
system (PIS)? Answer: Alerts regarding allergies and interactions
◉1. Standardized terminology was implemented to promote
interoperability across electronic health records (EHRs). Which
terminology is specific to laboratory tests, orders, and results?
Answer: LOINC
◉1. A nurse performing patient discharge from a facility provides a
continuity of care document (CCD) to a patient and explains the
document and contents at discharge. What is a benefit provided by
the CCD? Answer: It provides a summary of care to patients and
clinicians.
◉1. What are patient portals? Answer: Patient portals are facility-
owned and associated with an electronic health record.
◉1. A hospital notes a decreased use of barcoded medication
administration (BCMA) along with an increase in medication errors.
What should be the next course of action? Answer: Monitor BCMA
usage reports for trends.
,◉1. A heparin medication error and a subsequent failure mode
effects analysis (FMEA) results in the purchase of smart pumps. How
do smart pumps reduce the potential for medication errors?
Answer: Dosing limits and alerts are provided.
◉1. Mobile health (mHealth) apps have demonstrated benefits to
patients by increasing engagement and participation in care. What is
a benefit for clinicians? Answer: Integrates with electronic health
records (EHRs)
◉1. A facility has noted a decrease in revenue related to inaccuracies
in coding. A nurse recommends computer-assisted coding (CAC) as a
solution. What is the financial benefit of CAC? Answer: CAC
improves coding accuracy.
◉1. A nurse manager is informed that bedside nurses have begun
using a workaround for scanning a patient's armband prior to
medication administration. The nurse manager finds that several
patients are missing armbands and that their armbands are
connected to their bed frames. What is the nurse manager's first
course of action for this workaround to bedside-scanning
technology? Answer: Question nursing staff about what issues have
caused this.
,◉1. Currently, a facility uses phones and pagers for clinician
communication. This technology is due for replacement. A nurse
recommends replacing with all-in-one mobile devices. What is the
benefit of all-in-one mobile technology over the current devices?
Answer: It integrates functionality within the EHR.
◉1. A nurse in a primary care provider's office needs to review
results from a patient's cardiology consultation. Using health
information exchange (HIE) technology, the nurse requests this
information from the cardiologist's office. Which type of exchange is
described? Answer: Query based.
◉1. An informatics nurse is working on genomics data to facilitate
disease identification and develop individualized treatment plans for
patients in a complex medical facility. What is considered a
fundamental requirement for valid interpretation of genomics data?
Answer: High throughput computing system
◉1. Which medical device is useful in establishing an effective
monitoring system for a patient with acute brain injury? Answer:
Temperature probe
◉1. An informatics nurse is collaborating with a nursing director of
a long-term care facility to address an ongoing issue with medication
errors. Which solution should they consider? Answer: Use digital
platform and barcode systems.
, ◉1. What are the correct steps in medication administration that
require scanning verification? Answer: Scan the serial numbers on
the medication label and patient's identification bracelet.
◉1. Which healthcare data set would allow identification of
performance gaps and establishment of realistic targets for
improvement? Answer: Healthcare Effectiveness Data and
Information Set (HEDIS)
◉1. Which situation places a clinical decision support system (CDSS)
at risk for corrupt datasets? Answer: A nurse updates a patient's
medical history after learning of a medical condition via social
media.
◉1. A team of healthcare workers were stunned when a reality show
actor was brought to their emergency unit. A few of them took
videos of the actor and streamed them live on social media. Which
law did the healthcare workers possibly violate? Answer: Health
Insurance Portability and Accountability Act (HIPAA)
◉1. The nursing unit of a major hospital is revisiting their policy on
the use of mobile devices for accessing the EMR. Which guideline
should take precedence? Answer: Ensure legal and regulatory
compliance.
