WGU D547 Evidence-Based Healthcare Administration
Examination 2026-2027 Comprehensive 150 -Question Practice
Test with Answers & Rationales Free Pdf Access
This comprehensive examination assesses graduate-level competency in evidence-based healthcare
administration, integrating appraisal of research evidence, clinical practice guidelines, quality improvement
methodologies, health informatics, policy, leadership, ethics, and interprofessional collaboration to drive safe,
high-value care. It contains 159 multiple-choice questions, each with four distractors and a fully worked rationale
that explains why the keyed answer is correct. Questions are organized into clearly labelled sections that mirror
the major content areas of the course. Targeted learning outcomes include: Critically appraise and synthesize
research evidence to inform administrative and clinical decisions.; Apply evidence-based frameworks (e.g., IHI
Model for Improvement, EBP models) to design and evaluate quality improvement initiatives.; Analyze healthcare
policy, regulatory, ethical, and informatics factors influencing evidence-based practice and population health
outcomes.. Every item has been reviewed for clinical accuracy, current guidelines, and clarity so that students can
study with confidence and self-correct as they work through the bank. Use it as a high-yield review immediately
before the exam, or as a structured practice tool during the unit - the rationales double as concise teaching notes.
The recommended writing time is 3 hours, with a passing score of 80% (40/50 correct). Aligned with Aligned with
WGU D547 course competencies (2026-2027) and US graduate healthcare administration standards; content
reflects current guidelines from IHI, AHRQ, Joint Commission (2026), HIPAA (2026 updates), and ACA
Section 1: General (Questions 1-159)
1 Which design best minimizes selection bias when evaluating a new care
coordination model?
A) Prospective cohort study with convenience sampling
B) Randomized controlled trial with concealed allocation
C) Retrospective chart review with matched controls
D) Quasi-experimental pre-post design with historical controls
Answer: B
Rationale: Randomized controlled trials with concealed allocation minimize
selection bias by ensuring unbiased group assignment. Cohort and
quasi-experimental designs are susceptible to confounding and selection bias, while
retrospective reviews are limited by data quality and lack of randomization.
2 In the IHI Model for Improvement, what is the primary purpose of the
'Plan-Do-Study-Act' cycle?
A) To establish statistical process control limits
B) To test small-scale changes and learn from them iteratively
C) To conduct a full-scale randomized trial of an intervention
D) To obtain regulatory approval for a new clinical protocol
Answer: B
,Rationale: The PDSA cycle is a rapid-cycle improvement method used to test
changes on a small scale, learn from the results, and adapt before broader
implementation. It is not intended for statistical process control, randomized trials,
or regulatory approval.
3 Which metric most directly evaluates the internal validity of a clinical practice
guideline?
A) The number of participating specialty societies
B) The clarity of the recommendation wording
C) The rigor of the evidence synthesis and grading process
D) The frequency of guideline updates
Answer: C
Rationale: Internal validity of a guideline depends on the rigor of the evidence
review, including systematic search, critical appraisal, and transparent grading.
Participating societies, wording clarity, and update frequency are important but do
not directly assess internal validity.
4 A hospital's central line-associated bloodstream infection rate is 2.5 per 1,000
line-days. Which action best reflects evidence-based practice?
A) Increase antibiotic prophylaxis for all central line insertions
B) Implement a bundle including hand hygiene, maximal barrier precautions, and
chlorhexidine skin antisepsis
C) Replace all central lines every 72 hours to prevent infection
D) Restrict central line insertion to intensivists only
Answer: B
Rationale: Evidence-based bundles (e.g., hand hygiene, maximal barrier precautions,
chlorhexidine antisepsis) significantly reduce CLABSI rates. Routine antibiotic
prophylaxis, scheduled line replacement, and restricting insertion to intensivists are
not supported by evidence and may introduce other risks.
5 Which informatics tool best supports real-time clinical decision support for
medication ordering?
A) Electronic health record with computerized provider order entry and alerts
B) Standalone pharmacy inventory management system
C) Paper-based medication administration record
D) Scheduled monthly medication reconciliation audit
Answer: A
Rationale: CPOE with integrated clinical decision support alerts provides real-time
,guidance during ordering, reducing errors. Standalone inventory systems, paper
records, and retrospective audits do not offer real-time decision support at the point
of care.
6 Which policy mechanism under the Affordable Care Act most directly
incentivizes evidence-based care?
A) Medicaid expansion
B) Health insurance marketplaces
C) Hospital Value-Based Purchasing Program
D) Individual mandate penalty
Answer: C
Rationale: The Hospital Value-Based Purchasing Program links a portion of
Medicare payments to quality and outcomes, directly incentivizing evidence-based
care. Medicaid expansion and marketplaces expand coverage but do not directly tie
payment to evidence-based performance.
7 Which leadership approach best fosters sustainable evidence-based practice
change?
A) Transactional leadership with strict compliance monitoring
B) Transformational leadership with shared governance and frontline engagement
C) Laissez-faire leadership allowing autonomous adoption
D) Autocratic leadership with top-down mandates
Answer: B
Rationale: Transformational leadership with shared governance engages frontline
staff, builds commitment, and supports sustained practice change. Transactional,
laissez-faire, and autocratic approaches are less effective for long-term
evidence-based practice integration.
8 Which ethical principle is most directly upheld when obtaining informed consent
for a research study?
A) Beneficence
B) Justice
C) Autonomy
D) Nonmaleficence
Answer: C
Rationale: Informed consent respects participants' autonomy by ensuring voluntary,
informed decision-making. Beneficence, justice, and nonmaleficence are important
ethical principles but are not the primary principle directly upheld by informed
, consent.
9 Which interprofessional collaboration strategy most effectively reduces
medication errors during care transitions?
A) Physician-only medication reconciliation
B) Nurse-led discharge instructions without pharmacist review
C) Team-based medication reconciliation with pharmacist involvement
D) Electronic prescribing without interprofessional communication
Answer: C
Rationale: Team-based medication reconciliation with pharmacist involvement
reduces errors by leveraging diverse expertise. Physician-only, nurse-led without
pharmacist, and electronic prescribing without communication are less effective and
may miss critical discrepancies.
10 Which statistical measure best quantifies the consistency of a diagnostic test's
results across repeated measurements?
A) Sensitivity
B) Specificity
C) Positive predictive value
D) Reliability coefficient (e.g., kappa)
Answer: D
Rationale: Reliability coefficients such as kappa assess the consistency or agreement
of repeated measurements. Sensitivity, specificity, and predictive values assess
accuracy against a gold standard, not consistency across repetitions.
11 A hospital's EBP council must select the most rigorous framework for translating
evidence into practice. Which model best addresses contextual readiness and
sustainability?
A) Stetler Model of Research Utilization
B) Iowa Model of Evidence-Based Practice
C) PARIHS/Integrated-Promoting Action on Research Implementation in Health
Services
D) ACE Star Model of Knowledge Transformation
Answer: C
Rationale: PARIHS (and its revised i-PARIHS) explicitly theorizes successful
implementation as a function of evidence, context, and facilitation, making
contextual readiness and sustainability central rather than peripheral. The Stetler and
Iowa models emphasize practitioner-level research utilization and organizational
