ACBN Research & Evidence-Based Practice 4

Question 1

When translating research findings into clinical practice, which step is most critical in the evidence-based practice model?

Accepted Answer

Integrating research evidence with clinical expertise and patient values

Answer

Evidence-based practice requires integrating the best available research evidence with clinical expertise and individual patient values and preferences.

Question 2

A nutritionist identifies a statistically significant result (p<0.05) showing that a supplement reduces HbA1c by 0.05%. The clinician should recognize that:

Accepted Answer

A small effect can be statistically significant but not clinically meaningful

Answer

Statistical significance depends on sample size and does not ensure that an effect is large enough to be clinically meaningful or worth recommending.

Question 3

Publication bias in nutrition research refers to the tendency for:

Accepted Answer

Positive or significant results to be published more frequently than null findings

Answer

Publication bias skews the evidence base because studies with null or negative results are less likely to be published, inflating the apparent efficacy of interventions.

Question 4

In a prospective cohort study examining diet and cancer risk, confounding occurs when:

Accepted Answer

A third variable is associated with both the diet exposure and the cancer outcome

Answer

A confounder is a variable that is associated with both the exposure and the outcome, potentially creating a spurious or distorted association.

Question 5

The GRADE system in nutrition research is used to:

Accepted Answer

Rate the overall certainty of evidence for specific outcomes across a body of literature

Answer

GRADE (Grading of Recommendations Assessment, Development and Evaluation) classifies the certainty of a body of evidence as high, moderate, low, or very low.
