,1. A healthcare organization is implementing a new clinical decision support (CDS)
system to reduce adverse drug events. The system will alert prescribers when a
medication order conflicts with a patient's laboratory results. Which of the following
is the most critical consideration to prevent alert fatigue and ensure the CDS system
improves patient safety?
A. Increasing the threshold for triggering alerts to reduce the total number of alerts generated
B. Integrating the CDS with the electronic health record (EHR) to allow one-click override
without documentation
C. Designing alerts with actionable recommendations and requiring a reason for override
D. Limiting alerts to only those mandated by regulatory bodies such as The Joint
Commission
Answer: C. Designing alerts with actionable recommendations and requiring a
reason for override
To combat alert fatigue, alerts must be clinically relevant, actionable, and require a
reason for override. This ensures that clinicians engage with the alert and consider the
recommendation, thereby enhancing safety. Increasing thresholds (A) may suppress
important alerts, while allowing one-click overrides (B) undermines the purpose of
CDS. Limiting to regulatory alerts (D) misses many evidence-based opportunities to
prevent errors.
2. A nurse informaticist is evaluating the usability of a new mobile application for
patient self-reporting of pain levels. Which of the following usability testing methods
would provide the most valid and reliable data on how the application performs in a
real-world clinical environment?
A. Heuristic evaluation conducted by a panel of informatics experts
B. Remote unmoderated testing with a large sample of diverse patients
C. Controlled laboratory testing with standardized tasks and trained actors
D. In situ observation of patients using the app during actual clinic visits
Answer: D. In situ observation of patients using the app during actual clinic visits
In situ observation captures real-world context, including distractions, workflow
interruptions, and actual patient behaviors, providing high ecological validity. Heuristic
evaluation (A) is expert-based but lacks user interaction. Remote unmoderated testing
(B) may miss contextual factors. Controlled laboratory testing (C) can be artificial and
not reflect real clinic dynamics.

,3. A nurse manager notices that the unit's documentation compliance rate for
pressure injury risk assessments has dropped below 90%. The current workflow
requires nurses to complete the Braden Scale within 24 hours of admission. Which of
the following informatics interventions is most likely to sustainably improve
documentation compliance without increasing cognitive burden?
A. Implementing a mandatory pop-up reminder that appears each time a nurse opens a
patient's chart until the assessment is completed
B. Integrating the Braden Scale into the admission nursing note template as a required field
with auto-calculation of the score
C. Sending daily email reports to nurses listing patients who are missing the assessment
D. Adding a hard stop in the EHR that prevents chart closure until the Braden Scale is
documented
Answer: B. Integrating the Braden Scale into the admission nursing note template
as a required field with auto-calculation of the score
Embedding the Braden Scale into the existing workflow (admission note) reduces the
need for separate data entry and minimizes disruption. Auto-calculation further eases
cognitive load. Pop-up reminders (A) can cause alert fatigue. Email reports (C) may be
ignored or not read in a timely manner. Hard stops (D) are disruptive and can lead to
workarounds or frustration, potentially harming patient care.

, 4. A hospital is adopting Fast Healthcare Interoperability Resources (FHIR)
standards to enable data exchange with a regional health information exchange
(HIE). Which of the following is a key advantage of using FHIR over older standards
like HL7 v2?
A. FHIR supports only RESTful APIs, eliminating the need for SOAP-based communication
B. FHIR uses a resource-based model that allows granular access to individual data elements
C. FHIR requires all data to be transmitted in XML format, ensuring strict validation
D. FHIR is backward compatible with HL7 v2, allowing seamless integration with legacy
systems
Answer: B. FHIR uses a resource-based model that allows granular access to
individual data elements
FHIR's resource-based model (e.g., Patient, Observation, MedicationRequest) enables
fine-grained access to specific data elements, facilitating targeted data exchange and
reducing bandwidth. While FHIR commonly uses RESTful APIs, it can also use other
paradigms (A is too absolute). FHIR supports multiple formats including JSON and
XML, not just XML (C). FHIR is not backward compatible with HL7 v2; they are
different standards (D).
5. A nurse informaticist is analyzing a dataset of patient falls to identify risk factors.
The dataset includes 10,000 records with 500 falls (5% incidence). The informaticist
uses logistic regression to develop a predictive model. Which of the following
evaluation metrics is most appropriate for assessing the model's performance given
the class imbalance?
A. Accuracy
B. Area under the receiver operating characteristic curve (AUC-ROC)
C. F1 score
D. Mean absolute error (MAE)
Answer: C. F1 score
With class imbalance (5% falls), accuracy (A) can be misleadingly high (e.g., always
predicting no fall gives 95% accuracy). AUC-ROC (B) is less sensitive to imbalance but
still can be optimistic. F1 score (harmonic mean of precision and recall) is more
appropriate as it balances false positives and false negatives. MAE (D) is for continuous
outcomes, not binary classification.
