Question 1
What is the primary purpose of evidence-based practice (EBP) in
nursing?
A. To rely solely on personal clinical experience
B. To integrate the best available research evidence, clinical expertise,
and patient preferences into healthcare decisions
C. To eliminate the need for nursing judgment
D. To replace all clinical guidelines with research articles
Correct Answer: B. To Integrate the Best Available Research Evidence,
Clinical Expertise, and Patient Preferences into Healthcare Decisions
Rationale:
Evidence-based practice combines current, high-quality research,
clinical expertise, and patient values to improve healthcare outcomes
and ensure safe, effective nursing care.
Question 2
Which type of research is primarily concerned with understanding
human experiences, beliefs, and behaviors?
