A) A true PICO question, because the outcome always comes before the intervention.
B) A true PICO question regardless of placement of elements.
C) Not a true PICO question, because the comparison comes after the intervention.
D) Not a true PICO question, because the outcome comes after the population.

Question 9

A) Excludes all bias.
B) Uses randomization in structure.
C) Determines associations between variables and conditions.
D) Studies phenomena that are difficult to quantify.

Question 10

When evaluating quality improvement (QI)programs in relation to evidence-based practice (EBP),it is easy to note that

B) When implementing EBP projects, it is important to review QI data.
C) EBP is not at all related to QI.
D) Evaluation of processes is the realm of performance improvement (PI), not QI.

Question 11

A) Anonymity.
B) Confidentiality.
C) Informed consent.
D) The research process.

Question 12

A) Experimental research
B) Surveys
C) Evaluation research
D) Phenomenology
E) Grounded theory

Question 13

The first step in evidence-based practice is to ask a clinical question.In doing so,the nurse needs to realize that in researching interventions,the question

B) Will lead you to hundreds of articles that must be read.
C) May be easier if in PICO format.
D) May be more useful the more general it is.

Question 14

A) MEDLINE
B) EMBASE
C) PsycINFO
D) AHRQ

C) Dependent on patient values and expectations.
D) Not shown to provide better patient outcomes.

Question 16

The hospital's quality improvement committee has identified a problem on one of the units.In using the PDSA method to help determine ways to deal with the issue,the committee decides to do a literature review.This is an example of quality improvement

A) Combined with evidence-based practice.
B) With inability to make the right decision.
C) With delay in the action needed.
D) With no designated method for dealing with issues.

C) Literature review or background.
D) Results.

Question 19
