A nurse educator integrates the Iowa Model of Evidence-Based Practice. What is the FIRST trigger that initiates the EBP process in this model?
Answer: Identifying a problem-focused or knowledge-focused trigger
The Iowa Model begins with identifying either a problem-focused trigger (clinical issue) or knowledge-focused trigger (new research) that prompts the EBP process.
Which type of validity refers to whether a research instrument actually measures the construct it is intended to measure?
Answer: Construct validity
Construct validity assesses whether an instrument truly measures the theoretical concept (construct) it was designed to measure.
In a clinical trial comparing two nursing education interventions, participants and outcome assessors are unaware of group assignment. This describes:
Answer: Double-blind study
A double-blind study keeps both participants and outcome assessors unaware of group allocation, minimizing performance and detection bias.
A nurse educator wants to measure the strength of the relationship between clinical hours and NCLEX scores. Which statistic is MOST appropriate?
Answer: Pearson correlation coefficient
Pearson correlation coefficient measures the strength and direction of the linear relationship between two continuous variables.
An IRB requires a 'Certificate of Confidentiality' for a nursing research study. This certificate PRIMARILY protects:
Answer: Participants' identifiable data from compelled disclosure in legal proceedings
A Certificate of Confidentiality protects identifiable research data from forced disclosure in court proceedings, protecting participant privacy.
In translational research (T1–T4), which phase focuses on moving findings from 'bench to bedside' — from basic science to clinical application?
Answer: T1
T1 translational research moves discoveries from basic laboratory science to first-in-human applications, representing the bench-to-bedside transition.
A nurse educator critiques a study and finds that attrition was 35% by follow-up. The PRIMARY concern is:
Answer: Threats to internal validity due to attrition bias
High attrition threatens internal validity because those who drop out may differ systematically from those who remain, introducing attrition bias.
