2025/2026 UPDATE!!
SECTION 1: PICOT QUESTION FORMATION & EVIDENCE LEVELS (Questions 1–5)
Q1: A DNP student wants to reduce catheter-associated urinary tract infections (CAUTI) in a
medical-surgical unit. Which PICOT question contains all required elements correctly
structured?
A. In hospitalized adults, does chlorhexidine bathing compared to standard soap reduce CAUTI
rates within 30 days?
B. Does chlorhexidine bathing reduce infections in hospitals?
C. In adults, how does chlorhexidine compare to soap for reducing CAUTI?
D. Among hospitalized patients, is chlorhexidine bathing effective?
Correct Answer: A
Rationale: Correct because this PICOT includes Population (hospitalized adults), Intervention
(chlorhexidine bathing), Comparison (standard soap), Outcome (CAUTI rates), and Time (within
30 days). Option B lacks comparison, outcome specificity, and time. Option C lacks a defined
population and time frame. Option D lacks comparison, specific outcome measurement, and
time. Priority is ensuring all five PICOT elements are present and precisely defined for literature
search feasibility.
Q2: A DNP student is evaluating evidence for a systematic review on nurse-led heart failure
education. According to the evidence pyramid, which source represents the highest level of
evidence?
A. A single randomized controlled trial (RCT) published in a peer-reviewed journal
, B. A systematic review of RCTs with meta-analysis published by the Cochrane Collaboration
C. An expert opinion column written by a cardiology nurse practitioner
D. A qualitative phenomenological study exploring patient experiences with heart failure
Correct Answer: B
Rationale: Correct because a systematic review of RCTs with meta-analysis represents Level I
evidence, the apex of the evidence pyramid. This matches the hierarchy where synthesized
evidence from multiple well-designed RCTs provides the strongest foundation for EBP
recommendations. Option A represents Level II evidence (single RCT). Option C represents Level
VII evidence (expert opinion). Option D represents Level VI evidence (single descriptive or
qualitative study). Priority is selecting the highest available evidence level for clinical decision-
making.
Q3: A DNP student is formulating a PICOT question for an EBP change project focused on
reducing 30-day readmission rates among patients with chronic obstructive pulmonary disease
(COPD). Which element is MISSING from the following PICOT statement: "In adults with COPD
(P), does a telehealth monitoring program (I) compared to standard discharge instructions (C)
reduce 30-day hospital readmissions (O)?"
A. Intervention specificity
B. Comparison clarity
C. Time frame
D. Outcome measurability
Correct Answer: C
Rationale: Correct because the PICOT statement as written lacks a defined Time element. While
the outcome mentions "30-day readmissions," the time frame for the EBP initiative
implementation and evaluation is not specified. This matches the requirement that Time in
PICOT refers to the duration of the intervention or the target date of completion, not merely the
outcome measurement window. Option A is incorrect because the intervention (telehealth
monitoring program) is sufficiently specific. Option B is incorrect because standard discharge
instructions provide a clear comparison. Option D is incorrect because 30-day readmissions is a
measurable outcome. Priority is ensuring all five PICOT components are explicitly articulated.
