The researcher must critically appraise evidence following a literature review. Which questions should the researcher pose in this appraisal?
- A. How many studies were found during the review?'
- B. What were the results of each study?'
- C. Are the results of each study valid and reliable?'
- D. Will the results of each study improve client care?'
Correct Answer: C
Rationale: Critical appraisal in nursing research evaluates evidence quality and relevance post-literature review, ensuring findings guide practice effectively. Asking 'What were the results of each study?' identifies outcomes like reduced infection rates while 'Are the results valid and reliable?' assesses methodological rigor, checking biases or sample issues. 'Will the results improve client care?' gauges practical impact, linking evidence to real-world benefits. 'How many studies were found?' or 'Where were they conducted?' provide context but don't appraise quality. This process filters robust evidence like a study on hand hygiene reducing infections ensuring nurses apply trustworthy, applicable insights. It's a gatekeeper, preventing flawed data from skewing care, and aligns research with nursing's goal of enhancing patient outcomes through science, not just volume or geography.

- C. Pain and swelling
- D. Alignment and position
Correct Answer: B
