EXAM 1: Foundations, EBP, and Perioperative Care
1. 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.
,2. 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).
3. A new graduate nurse is unsure where to find reliable information about best
practices for preventing pressure injuries. 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.
4. After reviewing recent research on fall prevention, a hospital introduces hourly
rounding. Nurses also individualize care by asking patients if they prefer dim
lighting or a nightlight at bedtime. 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: 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.
5. 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.
6. 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. Embedding the fall risk tool into admission paperwork is a practical
application. Evaluating (B) and sharing (D) are later steps.
, 7. 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.
8. 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 outcomes is Step 6 of EBP. The goal is to communicate results
to peers, councils, or broader professional communities.
9. A nurse is preparing a patient for surgery. Who is legally responsible for
obtaining informed consent from the patient?
A. The registered nurse
B. The anesthesia provider
