Nursing Research: Generating and Assessing Evidence for Nursing Practice
SECTION 1: FOUNDATIONS OF NURSING RESEARCH & EVIDENCE-BASED
PRACTICE (Questions 1–30)
Question 1. What is the primary purpose of nursing research?
A) To generate revenue for healthcare institutions
B) To provide evidence for informing nurses' decisions and actions
C) To replace clinical judgment with standardized protocols
D) To satisfy accreditation requirements
Correct Answer: B
Rationale: The primary purpose of nursing research is to generate evidence that
informs nurses' decisions and actions, ultimately improving patient outcomes and
advancing the profession.
Question 2. Which statement best describes evidence-based practice (EBP)?

,Page 2 of 145
A) Nursing care based on tradition and intuition
B) A problem-solving approach that integrates the best available evidence, clinical
expertise, and patient preferences
C) Using only randomized controlled trials to make all clinical decisions
D) A method for reducing healthcare costs
Correct Answer: B
Rationale: EBP is a problem-solving approach that integrates the best available research
evidence with clinical expertise and patient values and preferences.
Question 3. In the PICOT format, what does the "P" represent?
A) Patient population or problem of interest
B) Primary outcome
C) Protocol
D) Provider
Correct Answer: A
Rationale: In PICOT, "P" stands for the patient population or problem of interest, which
defines the group being studied.
Question 4. What does the "I" in PICOT represent?
A) Intervention or issue of interest
B) Implementation

C) Investigation
D) Indicator
Correct Answer: A
Rationale: The "I" in PICOT represents the intervention or issue of interest—the
treatment, exposure, or diagnostic test being considered.
Question 5. Which PICOT component represents the comparison or control group?
A) O
B) T
C) C
D) P
Correct Answer: C
Rationale: The "C" in PICOT stands for the comparison or control group—what the
intervention is being compared against (e.g., standard care, placebo, or another

Question 6. What does the "O" in PICOT refer to?
A) Outcome of interest
B) Objective
C) Observation
D) Organization

Correct Answer: A
Rationale: The "O" in PICOT refers to the outcome of interest—the result or endpoint
being measured.
Question 7. What does the "T" in PICOT represent?
A) Timeframe
B) Treatment
C) Theory
D) Type of study
Correct Answer: A
Rationale: The "T" in PICOT represents the timeframe for the study or the time it takes
for the outcome to be achieved.
Question 8. Which of the following is the FIRST step in the EBP process?
A) Conducting a randomized controlled trial
B) Formulating a clinical question using PICOT
C) Implementing a change in practice
D) Evaluating patient outcomes
Correct Answer: B
Rationale: The first step in the EBP process is formulating a clinical question, often
using the PICOT format, to guide the search for evidence.
