Question 1: A nurse uses an electronic health record to retrieve patient
information, evaluates the reliability of the information, and applies the
findings to support a clinical decision. Which informatics competency is being
demonstrated most directly?
A. Basic computer literacy
B. Information literacy
C. Hardware maintenance
D. Database programming
CORRECT ANSWER: B. Information literacy
Rationale: Information literacy is the ability to recognize when information is
needed and to locate, evaluate, and use it effectively. The nurse in this scenario
retrieves, evaluates, and applies patient information to clinical decision-making,
which is the hallmark of information literacy rather than basic computer literacy
or technical skills.
Question 2: A healthcare organization is considering implementation of a new
electronic health record system. Before selecting a vendor, the organization
analyzes its current workflows, identifies gaps, and determines what
functionality is actually needed. Which phase of the system life cycle is
represented?
A. System implementation
B. System retirement
C. Needs assessment
D. Vendor contracting
CORRECT ANSWER: C. Needs assessment
Rationale: The needs assessment phase of the system life cycle involves analyzing
current workflows, identifying gaps, and determining required functionality
,before any vendor selection or implementation occurs. This foundational step
ensures the selected system will meet organizational requirements.
Question 3: A hospital's selection committee is comparing several EHR vendors.
Which consideration should receive the greatest emphasis when determining
whether a proposed system is appropriate?
A. Whether the system has the most visually appealing interface
B. Whether the system supports organizational goals, clinical workflows, patient
safety, and user requirements
C. Whether the vendor has the largest advertising budget
D. Whether the software contains the greatest number of optional features
regardless of clinical relevance
CORRECT ANSWER: B. Whether the system supports organizational goals,
clinical workflows, patient safety, and user requirements
Rationale: The primary criterion for EHR selection should be whether the system
supports the organization's clinical and operational goals, enhances patient
safety, fits existing workflows, and meets user needs. Aesthetic appeal,
advertising budget, and feature quantity are secondary considerations that do not
ensure clinical appropriateness.
Question 4: A nurse informaticist participates in redesigning a medication
administration workflow after implementation of a new electronic system.
Which outcome would best demonstrate successful workflow integration?
A. Nurses develop workarounds to bypass required documentation
B. The system increases duplicate documentation requirements
C. The technology supports efficient clinical processes while maintaining accurate
and timely patient information
D. Staff members avoid using the electronic system whenever possible
CORRECT ANSWER: C. The technology supports efficient clinical processes while
maintaining accurate and timely patient information
Rationale: Successful workflow integration is demonstrated when technology
enhances rather than impedes clinical processes, allowing efficient care delivery
,while preserving data accuracy and timeliness. Workarounds and avoidance
behaviors indicate failed integration.
Question 5: Which statement best distinguishes data from information in
healthcare?
A. Data are interpreted findings, whereas information consists only of raw
observations
B. Data are raw facts or observations, whereas information is data that have been
organized and interpreted to provide meaning
C. Data and information are interchangeable terms with no meaningful distinction
D. Information can exist only when it is stored electronically
CORRECT ANSWER: B. Data are raw facts or observations, whereas information
is data that have been organized and interpreted to provide meaning
Rationale: Data represent unprocessed facts or observations, such as vital sign
measurements. Information emerges when data are organized, analyzed, and
interpreted to convey meaning. This distinction is fundamental to nursing
informatics and the DIKW framework.
Question 6: A patient's temperature, heart rate, respiratory rate, blood
pressure, and oxygen saturation are entered into the EHR. At the time of entry,
these individual measurements are best classified as:
A. Knowledge
B. Wisdom
C. Data
D. Information
CORRECT ANSWER: C. Data
Rationale: Individual vital sign measurements entered into the EHR represent raw
data points. They become information only after being interpreted in context,
such as recognizing that a temperature of 39.5°C indicates fever requiring
intervention.
Question 7: A clinical decision-support system alerts a nurse that a prescribed
medication may interact with another medication already documented in the
patient's EHR. What is the primary purpose of this technology?
, A. Replace the nurse's clinical judgment
B. Provide information that can support safer clinical decision-making
C. Eliminate the need for medication reconciliation
D. Automatically determine the patient's diagnosis
CORRECT ANSWER: B. Provide information that can support safer clinical
decision-making
Rationale: Clinical decision-support systems are designed to augment, not
replace, clinical judgment by providing timely information and alerts that support
safer decision-making. They do not eliminate the need for nursing assessment or
medication reconciliation.
Question 8: A nurse receives a clinical decision-support alert but determines
that the warning does not apply because the patient's documented allergy is
incorrect. What is the most appropriate action?
A. Ignore all future alerts from the system
B. Override the alert without reviewing the patient's record
C. Verify and correct the underlying patient information according to
organizational policy
D. Disable the clinical decision-support system
CORRECT ANSWER: C. Verify and correct the underlying patient information
according to organizational policy
Rationale: When a CDS alert appears inappropriate due to incorrect
documentation, the nurse should verify the information and correct it following
organizational policy. Ignoring alerts, overriding without review, or disabling the
system are unsafe practices that could compromise patient safety.
Question 9: A hospital introduces computerized provider order entry (CPOE).
Which benefit is most directly associated with this technology?
A. It eliminates the need for provider decision-making
B. It can reduce errors associated with illegible handwritten orders and facilitate
electronic order processing
C. It prevents all medication errors regardless of workflow
D. It eliminates the need for nurses to verify orders
