WGU D220 INFORMATICS QUESTIONS AND
ANSWERS GRADED A+ (ACCURATE SOLUTIONS)
1. What is informatics?
A. A study of human behavior
B. A specialty science that facilitates the transformation of data into
information, knowledge, and wisdom
C. A type of medical device
D. A government regulation
Answer: B
Explanation: Informatics is the discipline focused on how data can be
transformed into useful information, then knowledge, and eventually wisdom
to support decision-making in healthcare and other fields. It combines
technology, processes, and human understanding. This transformation is
essential for improving patient care and system efficiency.
2. Which of the following are considered patient data?
A. Hospital-acquired infections
B. Name, age, weight, vital signs
C. Trends in patient outcomes
D. Clinical guidelines
Answer: B
Explanation: Patient data refers to raw, unprocessed facts about the
patient, such as demographic information, vital signs, and physical
measurements. These are the foundational elements that can later be
processed into information or knowledge. Data alone does not provide
insights without analysis.
3. What is an example of information in healthcare?
A. Nurse-patient ratio vs. patient outcome
B. Hospital-acquired infections
C. Name, age, weight
D. Big data analytics
Answer: B
Explanation: Information is processed, organized, and contextualized data.
For example, tracking hospital-acquired infections organizes patient data
,into a meaningful metric. Unlike raw data, information can be acted upon to
improve care.
4. Which of the following is an example of knowledge in
healthcare?
A. Name, age, weight
B. Processed hospital-acquired infection rates
C. Identifying relationships, such as nurse-patient ratio vs. patient outcomes
D. Entering patient data into a database
Answer: C
Explanation: Knowledge involves understanding patterns or relationships
within information, allowing healthcare professionals to make informed
decisions. For example, linking nurse-patient ratios to outcomes helps in
planning staffing and improving care. Knowledge is actionable and insight-
driven.
5. Which three elements are included in an electronic health
record (EHR) system?
A. Data, information, knowledge
B. Hardware, software, networks
C. Nurses, physicians, administrators
D. Policies, procedures, protocols
Answer: A
Explanation: EHR systems capture and manage healthcare data,
transforming it into useful information and knowledge. Data is the raw input,
information is processed data, and knowledge represents insights derived
from the information. Together, these elements improve patient care and
system efficiency.
6. Which best describes information technology in
healthcare?
A. Using computers to play medical games
B. The process of searching, organizing, and managing data supported by
computers
C. Only storing patient records electronically
D. Teaching nurses to use social media
,Answer: B
Explanation: Information technology involves applying computers and
software to manage healthcare data efficiently. It includes searching,
organizing, and analyzing data to improve decision-making and patient
outcomes. Technology enables faster, more accurate, and secure healthcare
processes.
7. Translational bioinformatics primarily deals with:
A. Patient education
B. Storage, analysis, and interpretation of large volumes of biological and
clinical data
C. Hospital administration policies
D. Clinical trial enrollment
Answer: B
Explanation: Translational bioinformatics focuses on transforming large-
scale biological and clinical data into actionable insights. It helps researchers
and clinicians understand diseases, develop treatments, and personalize
patient care. It bridges bench research and bedside application.
8. Clinical research informatics is mainly concerned with:
A. Managing hospital finances
B. Discovery and management of knowledge from clinical trials and
secondary data
C. Implementing electronic health records only
D. Monitoring social media for health trends
Answer: B
Explanation: Clinical research informatics focuses on using data from
clinical trials and other sources to generate new knowledge about health and
disease. This discipline supports evidence-based decision-making and the
advancement of medical research. It ensures that data collected translates
into meaningful discoveries.
9. Clinical informatics focuses on:
A. Patient-centered, evidence-based care delivery
B. Coding hospital billing systems
C. Creating mobile health apps
D. Public health surveillance
, Answer: A
Explanation: Clinical informatics emphasizes using data and technology to
provide safe, timely, efficient, and patient-centered care. It integrates
electronic systems, clinical workflows, and decision support to improve
patient outcomes. It is key in modern healthcare delivery.
10. Consumer health informatics primarily focuses on:
A. The healthcare provider’s workflow
B. Enabling patients to manage their own health through structured tools
C. Hospital inventory management
D. Medical device development
Answer: B
Explanation: Consumer health informatics is patient-centered and aims to
empower individuals with tools and information to manage their health.
Examples include patient portals, mobile apps, and online educational
resources. It supports informed decision-making and self-care.
11. Public health informatics efforts include:
A. Individual patient record updates
B. Surveillance, prevention, health promotion, and preparedness
C. Hospital staffing schedules
D. Billing and revenue management
Answer: B
Explanation: Public health informatics applies data and technology to
population health initiatives. Activities include monitoring disease trends,
planning prevention programs, promoting wellness, and preparing for health
emergencies. It improves overall community health outcomes.
12. Information literacy is defined as:
A. Ability to read and understand written words and numbers, and recognize
when information is needed
B. Ability to use computers and software
C. Storing patient data in a spreadsheet
D. Teaching others how to code
Answer: A
Explanation: Information literacy includes identifying, locating, evaluating,
