Cardiac Vascular Nursing Exam Research & Evidence-Based Practice 4

Question 1

A cardiovascular nurse evaluates a clinical practice guideline from the American Heart Association (AHA). Which component indicates the STRENGTH of a recommendation?

Accepted Answer

Class of Recommendation (COR)

Answer

The AHA Class of Recommendation (COR) — ranging from I (strong benefit) to III (no benefit or harm) — indicates the strength of a guideline recommendation.

Question 2

In translational research, what does 'T2 translation' refer to in the context of cardiovascular nursing?

Accepted Answer

Translating clinical research findings into practice guidelines and policies

Answer

T2 translation refers to moving findings from clinical trials into health guidelines, clinical practice, and health policy — implementing proven interventions at scale.

Question 3

A nurse assesses the reliability of a new cardiac pain assessment tool. The tool is administered twice by the same nurse 48 hours apart with similar results. This BEST demonstrates:

Accepted Answer

Test-retest reliability

Answer

Test-retest reliability measures the consistency of a tool when administered to the same individuals under the same conditions at two different time points.

Question 4

Which statistical measure BEST quantifies the degree of agreement among multiple cardiac nurses rating the same patient's wound healing using an ordinal scale?

Accepted Answer

Cohen's kappa

Answer

Cohen's kappa is the appropriate statistic for measuring inter-rater agreement on categorical or ordinal data, adjusting for agreement expected by chance.

Question 5

A cardiac nurse reviews a diagnostic accuracy study on a new troponin assay. The study reports a sensitivity of 95% and specificity of 85%. What does the 85% specificity mean?

Accepted Answer

85% of patients without MI will correctly test negative

Answer

Specificity of 85% means the test correctly identifies 85% of individuals who do NOT have the condition as negative (true negatives).
