Nurse Executive Test Research & Evidence-Based Practice 2

Question 1

A nurse executive is evaluating a systematic review to guide a policy change. Which feature BEST distinguishes a systematic review from a narrative review?

Accepted Answer

Uses a predefined, reproducible search strategy with explicit inclusion criteria

Answer

Systematic reviews use a predefined, reproducible methodology with explicit inclusion/exclusion criteria to minimize bias, unlike narrative reviews.

Question 2

When applying the GRADE framework to rate evidence quality, which finding would result in UPGRADING the evidence level?

Accepted Answer

Large magnitude of effect with no plausible confounders

Answer

In GRADE, evidence can be upgraded when a very large effect size is present and confounding is unlikely to explain it.

Question 3

A nurse executive implements a new sepsis bundle and wants to measure its effect using a pre-post design. What is the PRIMARY limitation of this design?

Accepted Answer

Confounding variables and temporal trends may explain observed changes rather than the intervention

Answer

Pre-post designs lack a concurrent control group, making it impossible to rule out confounding or secular trends as causes of change.

Question 4

Which statistical measure best captures the clinical significance of an intervention when absolute risk reduction is small but relative risk reduction appears large?

Accepted Answer

Number needed to treat (NNT)

Answer

NNT translates absolute risk reduction into the number of patients who must be treated to prevent one adverse outcome, conveying practical clinical impact.

Question 5

A nurse executive is reviewing a study where the researcher collected data knowing which patients received the intervention. What bias does this MOST likely introduce?

Accepted Answer

Observer bias

Answer

Observer (or detection) bias occurs when knowledge of treatment assignment influences how outcomes are measured or recorded.
