,NR 500 Quiz 3 Foundational Concepts and Applications Questions
And Answers 2026/2027 chamberlain
1. A master's-prepared nurse is developing an evidence-based practice (EBP)
project. Which step occurs immediately after formulating a clinical question
using the PICOT format?
A) Critically appraising the evidence
B) Acquiring the best available evidence
C) Applying the evidence to practice
D) Evaluating the outcomes of the practice change
**Correct Answer:** B) Acquiring the best available evidence
**Rationale:** The EBP process involves a sequence of steps: Ask (formulate
a PICOT question), Acquire (search for evidence), Appraise (critically evaluate
the evidence), Apply (implement evidence in practice), and Assess (evaluate
outcomes). Acquiring evidence follows immediately after formulating the
question.
2. A nurse researcher is appraising a quantitative study. Which criterion is
most important for determining the internal validity of the study?
A) The study's ability to be generalized to other populations
B) The consistency of the measurements used in the study
C) The extent to which the study design rules out alternative explanations for
the findings
D) The statistical significance of the study findings
**Correct Answer:** C) The extent to which the study design rules out
alternative explanations for the findings
, **Rationale:** Internal validity refers to the degree to which a study's design
and methods support a cause-and-effect relationship and rule out
confounding variables. Generalizability relates to external validity,
consistency relates to reliability, and statistical significance is a measure of
probability.
3. An advanced practice nurse is implementing a new evidence-based
protocol for preventing pressure injuries. According to the Iowa Model of
Evidence-Based Practice, which step follows the identification of a trigger or
clinical problem?
A) Implementing the practice change
B) Critiquing and synthesizing the evidence
C) Forming a team to develop and implement the change
D) Evaluating the outcomes of the change
**Correct Answer:** C) Forming a team to develop and implement the
change
**Rationale:** The Iowa Model begins with identifying a trigger or clinical
problem. The next steps include forming a team, assembling and critiquing
evidence, and then implementing and evaluating the change. Forming a
team is a critical early step to ensure stakeholder engagement and
successful implementation.
4. A nurse is using the Stetler Model of Evidence-Based Practice. Which step
involves determining the relevance of the evidence to the practice setting?
A) Preparation
B) Validation
C) Comparative evaluation/decision
D) Translation/application
