Which of the following is a potential positive effect of evidence-based practice?

• A. Improved patient outcomes
• B. Potential cost savings
• C. All of the above
• D. Increased nurse satisfaction

Answer: (C)

Evidence-based practice blends the best available research with clinical expertise and patient values to guide care, which often leads to multiple positive outcomes. When care is aligned with solid evidence, patients tend to have better outcomes due to effective interventions and reduced practice variation. On the systems level, following proven guidelines can lower unnecessary tests and treatments, prevent complications, and optimize resource use, contributing to cost savings. Nurses also benefit from clear, evidence-backed protocols, which can boost confidence, consistency, and overall job satisfaction. Because these positive effects can occur together, all of the above is the best answer.
