Evidence-Based Practice & Research
Q1: A nurse on a surgical unit notices a rise in post-op wound infections. She
begins to wonder if using chlorhexidine for pre-op skin cleansing is more effective
than povidone-iodine. She decides to research the best practice for preventing
surgical site infections.
Which step of the Evidence-Based Practice (EBP) process is the nurse
demonstrating?
A. Searching for the most relevant evidence
B. Cultivating a spirit of inquiry
C. Integrating evidence with patient preferences
D. Evaluating outcomes of practice changes
Rationale: The nurse is questioning current practice and seeking clarification, which is
cultivating a spirit of inquiry (Step 0). Searching for evidence (A) happens after
developing a PICOT question. Integration (C) and evaluation (D) occur later.
Q2: A nurse in the ICU wants to know if elevating the head of the bed to 45
degrees, compared to 30 degrees, decreases ventilator-associated pneumonia
(VAP) rates within 7 days of intubation.
,Which part of the PICOT format does "within 7 days of intubation" represent?
A. Patient population (P)
B. Intervention (I)
C. Comparison (C)
D. Time (T)
Rationale: "Within 7 days of intubation" represents the Time (T) component. The patient
population is intubated ICU patients (P), intervention is elevating the head of the bed to
45 degrees (I), and comparison is 30 degrees (C).
Q3: A new graduate nurse is unsure where to find reliable information about best
practices for preventing pressure injuries. She plans to use her old class notes, ask
coworkers, and check social media groups.
Which of the following are appropriate sources of evidence for Evidence-Based
Practice? Select all that apply.
A. Peer-reviewed nursing and health care literature
B. Infection control data from the hospital
C. Benchmarking and chart review studies
D. Social media nursing groups
E. Standards of care from professional organizations
Rationale: Valid sources of evidence include peer-reviewed literature, infection control
data, benchmarking/chart reviews, and standards of care. Social media groups (D) are
not reliable sources for EBP.
Q4: A nurse reviews five recent articles related to reducing catheter-associated
urinary tract infections (CAUTIs). Two are randomized controlled trials, one is a
qualitative study, and the others are retrospective chart reviews. The nurse
compares the findings, examines their scientific rigor, and considers how the
results could apply to her hospital setting.
Which step of the EBP process is the nurse performing?
,A. Search for evidence
B. Critically appraise the evidence
C. Integrate evidence into practice
D. Evaluate outcomes
Rationale: The nurse is synthesizing and critiquing articles, considering scientific rigor
and application, which is Step 3: Critically appraise the evidence. Searching (A) happens
earlier, integrating (C) and evaluating (D) come later.
Q5: Research shows that using a standardized fall risk assessment tool reduces falls
in acute care settings. A nurse educator helps the staff implement this tool during
admission documentation and creates a teaching plan for new hires.
Which example best reflects integrating the evidence into practice?
A. Reading multiple fall-prevention research articles
B. Evaluating fall rates after a practice change
C. Embedding the fall risk tool into admission paperwork
D. Sharing fall-prevention outcomes at a professional conference
Rationale: Integrating evidence means applying it through teaching, tools, guidelines,
or policies. Evaluating (B) and sharing (D) are later steps. Reading (A) is evidence
collection, not integration.
Q6: A unit begins using chlorhexidine wipes for central line care based on current
evidence. After three months, the nurse manager reviews infection rates and notes
a 40% decrease in central line-associated bloodstream infections (CLABSIs).
What is the primary purpose of this step in the EBP process?
A. Determine if the practice change is effective
B. Disseminate the results to other organizations
C. Identify sources of evidence
D. Conduct a literature review
, Rationale: Step 5 (evaluate outcomes) ensures that changes are effective, modifications
are made if necessary, and unexpected results are identified before widespread
adoption.
Q7: After successfully reducing CAUTI rates with a new evidence-based catheter
care bundle, the nurse manager presents results to the hospital's nursing practice
council and submits an abstract to a national nursing conference.
Which EBP step is the nurse demonstrating?
A. Critically appraise the evidence
B. Evaluate outcomes
C. Share the outcomes with others
D. Conduct a quality improvement project
Rationale: Disseminating results is the final step of EBP (Step 6). The goal is to
communicate results to peers, councils, or broader professional communities.
Case Management & Continuity of Care
Q8: A nurse is caring for a patient recently diagnosed with metastatic lung cancer
who expresses concern about managing at home alone. The patient has limited
family support and lives alone in a rural area. Which action by the case manager is
the priority?
A. Arrange a referral to Meals on Wheels for food support
B. Refer the patient to a social worker for evaluation of available home support
C. Set up a follow-up appointment with the oncologist
D. Provide information about local cancer support groups
Rationale: While referrals to community services, oncology, and support groups are
important, the priority is assessing psychosocial support systems and home resources
through a social worker. This ensures safety and appropriate planning for home care
needs.
