Answer to Question 1

ANS: D
Randomized clinical trials (RCT) provide the strongest evidence for establishing evidence-based practice guidelines because of the strength of the research process.
Case studies provide neither the same rigor in the process nor generalizable results.
Expert opinion provides the lowest level of strength because it is not a conducted study.
Quasi-experimental studies often lack randomization and have limited generalizability of results.

Answer to Question 2

ANS: B
The main purpose of leveling research evidence in the establishment of evidence-based practice guidelines is to develop standard guidelines for providing care to clients that are based on the strongest evidence known, to improve the quality of care.
The purpose of a critique of a research article is to establish usefulness in one's particular practice.
This would be a potential offshoot of research evidence review; it is not the main purpose.
The purpose of a peer review before publication is to see that the establishment of the stated purpose or aim of the research was achieved.
