In respiratory care education, 'evidence-based practice' is best defined as:
Answer: Integrating best research evidence with clinical expertise and patient values
Evidence-based practice is a three-component model integrating the best available research, clinician expertise, and individual patient values and preferences.
Which study design provides the highest level of evidence in clinical research?
Answer: Randomized controlled trial (RCT)
Randomized controlled trials are the gold standard because random allocation minimizes selection bias and allows causal inference.
In diagnostic testing, 'sensitivity' refers to a test's ability to:
Answer: Correctly identify individuals with the disease (true positives)
Sensitivity measures the proportion of true positives — how reliably the test identifies patients who actually have the condition.
A p-value of 0.03 in a clinical study means there is a:
Answer: 3% probability the results occurred by chance
A p-value of 0.03 indicates a 3% probability that the observed difference between groups occurred due to random chance alone.
When clinical data is heavily skewed, which measure of central tendency is most appropriate to report?
Answer: Median
The median is preferred for skewed data because, unlike the mean, it is not distorted by extreme outlier values.
A systematic review differs from a narrative review primarily because it:
Answer: Uses predetermined criteria to identify and critically appraise studies
Systematic reviews follow explicit, reproducible methods with pre-specified inclusion criteria, minimizing selection bias compared to narrative reviews.
