  1. Multiple Choice Question: A nurse is leading a quality improvement project based on the latest evidence about reducing hospital-acquired infections. Which step of the EBP process does this activity best represent?
  • A. Formulating the clinically relevant question
  • B. Implementing the intervention
  • C. Evaluating outcomes and reflecting on the process
  • D. Disseminating evidence to the team Correct ANS : C. Evaluating outcomes and reflecting on the process Rationale: When a quality improvement project is undertaken to reduce infections, nursing staff use evidence to guide practice changes and then evaluate outcomes. Reflecting on the results is a critical step to ensure continuous improvement.

  1. Fill-in-the-Blank Question: The process of translating research findings into clinical practice is often referred to as __________ research.

Correct ANS : translational Rationale: Translational research focuses on bridging the “bench-to-bedside” gap, ensuring that discoveries from basic science and clinical research lead to improvements in patient care and health outcomes.


  1. True/False Question: True or False: Meta-analyses combine data from multiple randomized controlled trials to generate a more precise estimate of treatment effect. Correct ANS : True Rationale: Meta-analyses statistically pool data from several studies, increasing power and providing more robust estimates. This level of evidence is highly valued in EBP for guiding practice.

  1. Multiple Response Question: When reviewing the validity of research evidence, which indicators are most important to assess? (Select all that apply)
  • A. Internal validity
  • B. External validity
  • C. Reliability of measures
  • D. Consistency with personal beliefs
