The purpose of evidence-based practice is to:
validate traditional nursing practices.
improve patient outcomes.
dispute traditional nursing practices.
establish a body of knowledge unique to nursing
The Correct Answer is B
Evidence-based practice (EBP) is the conscientious integration of the best available research evidence, clinical expertise, and patient preferences to guide healthcare decisions.
Rationale for correct answer:
B. Improve patient outcomes: The central goal of EBP is to apply the most current, relevant, and high-quality evidence to clinical practice in order to deliver interventions that have been proven effective, thereby enhancing patient health, safety, and satisfaction.
Rationale for incorrect answers:
A. Validate traditional nursing practices: While EBP may confirm the effectiveness of some traditional practices, validation is not its main purpose. Instead, it evaluates all practices-traditional or new-against current scientific evidence.
C. Dispute traditional nursing practices: EBP does not aim to discredit tradition for its own sake. However, if evidence shows that a traditional practice is ineffective or harmful, EBP encourages modifying or replacing it. The focus is on patient benefit, not on opposing tradition.
D. Establish a body of knowledge unique to nursing: Building a nursing knowledge base is part of nursing research, which contributes to EBP. However, EBP itself focuses on applying knowledge (from nursing and other disciplines) to improve care, not solely on creating nursing-specific knowledge.
Take-home points:
- EBP aims to integrate best evidence, clinical expertise, and patient preferences to provide safe and effective care.
- Improving patient outcomes is the core purpose of EBP, not simply validating or disputing tradition.

Explanation
Advanced practice roles in nursing have expanded the scope of what nurses can do in clinical settings. Some of these roles include direct patient care at an advanced level, involving tasks traditionally associated with physicians, such as diagnosing conditions and prescribing treatment.
Rationale for correct answer:
C. A Nurse Practitioner is an Advanced Practice Registered Nurse (APRN) with training and licensure that allows them to obtain patient histories, conduct physical exams, order and interpret tests, diagnose medical conditions, and provide treatment, including prescribing medications.
Rationale for incorrect answers:
A. Clinical Nurse Specialist (CNS): A CNS is an advanced practice nurse who specializes in a particular area of nursing (e.g., pediatrics, oncology, critical care) and focuses on improving patient outcomes through consultation, education, research, and system improvement.
B. A case manager coordinates comprehensive care plans for patients, ensuring efficient use of resources and appropriate care transitions. They do not diagnose or treat patients and do not perform physical exams or order tests.
D. A nurse manager is responsible for supervising nursing staff, budgeting, scheduling, and ensuring compliance with policies. They typically do not provide direct patient care such as diagnosing or ordering tests in their administrative role.
Take home points:
- A Nurse Practitioner (NP) is a licensed advanced practice nurse who can diagnose and manage patient care independently, including ordering tests and prescribing treatments.
- Understanding the scope of each advanced nursing role ensures appropriate delegation, collaboration, and career planning within the nursing profession.
