Answer to Question 1

ANS: A

Feedback
A The highest level of those presented in the question is Summaries, which include clinical practice guidelines and electronic evidence-based textbooks. These summaries about specific conditions are updated regularly. An even higher level of the 6S pyramid is Computerized Decision Support Systems (CDSS), which integrate evidence-based clinical information into an electronic medical record. At present, these systems are not a reality in most institutions and, therefore, they were not included as an option in this question.
B Next highest is Synopsis of Synthesis, which provides a preappraised summary of a systematic review that can be found in journals, such as Evidence-Based Nursing.
C Third highest is Syntheses or systematic reviews such as a Cochrane review.
D Lowest in the hierarchy is Studies, which often refer to synopses of single studies evaluated by a single expert.

Answer to Question 2

ANS: B

Feedback
A The reviewers of the article may or may not know the identity of the other reviewers.
B In a blind review, the manuscript to be reviewed does not include the name of the author.
C A standard set of scholarly criteria is used to review the article. The criteria are usually known to the author.
D The criteria used to review the article are established by expert reviewers appointed by the publication's editors.
