MULTIPLE CHOICE

1. Which action would be most helpful for the nurse executive to implement evidence-based practice at a community nursing center that serves a large Cuban immigrant population?

ANS:   C

Although all of these options are good, to determine whether practice is serving the needs of the population, the nurse will need to consult the population served. This means that evidence should be applied with input from the community. For example, decisions related to the services to be offered in a nurse-managed clinic should be made with input from the clinic’s advisory board, which should include community leaders and consumers of the clinic’s services. Cuban immigrant needs may not be the same as those of Hispanic immigrants from other places such as Mexico or Spain.

2. The nurse has been reading everything she can find on a particular clinical problem, using both the closest medical library and the Internet. What would be the most helpful source if it were available?

ANS:   D

A systematic review is an approach to identifying, appraising, and synthesizing research evidence to evaluate and interpret all available research that is relevant to a particular research question. Systematic reviews can be accessed from most databases. Systematic reviews require more rigor and contain less opinion of the author than typical reviews of the literature.

4. After finding several studies related to the clinical problem, a nurse knows the studies must be evaluated. For the studies to be considered convincing, they should ideally be:

ANS:   B

The Agency for Healthcare Research and Quality (AHRQ) reviewed 40 systems used to evaluate the quality of studies and strength of evidence. The report identified three domains for evaluating systems that grade the strength of evidence: quality, quantity, and consistency. The quality of a study refers to the extent to which bias is minimized. Quantity refers to the number of studies, the magnitude of the effect, and the sample size. Consistency refers to studies that have similar findings, using similar and different study designs.
